    Changes of induction and competence during the evolution of vulva development in nematodes (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-07-01
    Description: In Caenorhabditis, the vulva is formed in the central body region from three of six equivalent cells and is induced by the gonad. In some nematodes, however, the vulva is located in the posterior body region. Vulval development has been analyzed in three such genera. The same precursor cells give rise to the vulva in Caenorhabditis and in the posterior vulva species, but in the latter the cells first migrate posteriorly. In two such species, the vulva is not induced by the gonad, but instead relies on intrinsic properties of precursor cells. Thus, evolution of organ position involves changes in induction and competence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sommer, R J -- Sternberg, P W -- New York, N.Y. -- Science. 1994 Jul 1;265(5168):114-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, California Institute of Technology, Pasadena 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8016644" target="_blank"〉PubMed〈/a〉

    Age of the earliest known hominids in Java, Indonesia (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-02-25
    Description: 40Ar/39Ar laser-incremental heating of hornblende separated from pumice recovered at two hominid sites in Java, Indonesia, has yielded well-defined plateaus with weighted mean ages of 1.81 +/- 0.04 and 1.66 +/- 0.04 million years ago (Ma). The hominid fossils, a juvenile calvaria of Pithecanthropus and a partial face and cranial fragments of Meganthropus, commonly considered part of the Asian Homo erectus hypodigm, are at least 0.6 million years older than fossils referred to as Homo erectus (OH-9) from Olduvai Gorge, Tanzania, and comparable in age with the oldest Koobi Fora Homo cf. erectus (Homo ergaster) in Kenya. These ages lend further credence to the view that Homo erectus may have evolved outside of Africa. If the ancestor of Homo erectus ventured out of Africa before 1.8 Ma, the dispersal would have predated the advent of the Acheulean culture at 1.4 Ma, possibly explaining the absence of these characteristic stone cleavers and hand axes in East Asia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Swisher, C C 3rd -- Curtis, G H -- Jacob, T -- Getty, A G -- Suprijo, A -- Widiasmoro -- New York, N.Y. -- Science. 1994 Feb 25;263(5150):1118-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Geochronology Center, Institute of Human Origins, Berkeley, CA 94709.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8108729" target="_blank"〉PubMed〈/a〉

    Developmental evolution: insights from studies of insect segmentation (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-10-28
    Description: Rapid advances have been made in the understanding of the genetic basis of development and pattern formation in a variety of model systems. By examining the extent to which these developmental systems are conserved or altered between different organisms, insight can be gained into the evolutionary events that have generated the diversity of organisms around us. The molecular and genetic basis of early pattern formation in Drosophila melanogaster has been particularly well studied, and comparisons to other insects have revealed conservation of some aspects of development, as well as differences that may explain variations in early patterning events.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Patel, N H -- New York, N.Y. -- Science. 1994 Oct 28;266(5185):581-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Embryology, Carnegie Institution of Washington, Baltimore, MD 21210-3399.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7939712" target="_blank"〉PubMed〈/a〉

    Kin selection, social structure, gene flow, and the evolution of chimpanzees (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-08-26
    Description: Hypotheses about chimpanzee social behavior, phylogeography, and evolution were evaluated by noninvasive genotyping of free-ranging individuals from 20 African sites. Degrees of relatedness among individuals in one community were inferred from allele-sharing at eight nuclear simple sequence repeat (SSR) loci. Males are related on the order of half-siblings, and homozygosity is significantly increased at several SSR loci compared to Hardy-Weinberg expectations. These data support the kin-selection hypothesis for the evolution of cooperation among males. Sequence variation patterns at two mitochondrial loci indicate historically high long-distance gene flow and clarify the relationships among three allopatric subspecies. The unexpectedly large genetic distance between the western subspecies, Pan troglodytes verus, and the other two subspecies suggests a divergence time of about 1.58 million years. This result, if confirmed at nuclear loci and supported by eco-behavioral data, implies that P. t. verus should be elevated to full species rank.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morin, P A -- Moore, J J -- Chakraborty, R -- Jin, L -- Goodall, J -- Woodruff, D S -- 1T32 HG00005-02/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 1994 Aug 26;265(5176):1193-201.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of California, San Diego, La Jolla 92093-0116.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7915048" target="_blank"〉PubMed〈/a〉

    The TATA-binding protein: a general transcription factor in eukaryotes and archaebacteria (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-05-27
    Description: The TATA-binding protein TBP appears to be essential for all transcription in eukaryotic cell nuclei, which suggests that its function was established early in evolution. Archaebacteria constitute a kingdom of organisms distinct from eukaryotes and eubacteria. Archaebacterial gene regulatory sequences often map to TATA box-like motifs. Here it is shown that the archaebacterium Pyrococcus woesei expresses a protein with structural and functional similarity to eukaryotic TBP molecules. This suggests that TBP's role in transcription was established before the archaebacterial and eukaryotic lineages diverged and that the transcription systems of archaebacteria and eukaryotes are fundamentally homologous.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rowlands, T -- Baumann, P -- Jackson, S P -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 1994 May 27;264(5163):1326-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome/CRC Institute, Cambridge, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8191287" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1994-08-19
    Description: DNA sequences for the gene encoding mitochondrial cytochrome oxidase I in a group of rodents (pocket gophers) and their ectoparasites (chewing lice) provide evidence for cospeciation and reveal different rates of molecular evolution in the hosts and their parasites. The overall rate of nucleotide substitution (both silent and replacement changes) is approximately three times higher in lice, and the rate of synonymous substitution (based on analysis of fourfold degenerate sites) is approximately an order of magnitude greater in lice. The difference in synonymous substitution rate between lice and gophers correlates with a difference of similar magnitude in generation times.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hafner, M S -- Sudman, P D -- Villablanca, F X -- Spradling, T A -- Demastes, J W -- Nadler, S A -- New York, N.Y. -- Science. 1994 Aug 19;265(5175):1087-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Museum of Natural Science, Baton Rouge, LA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8066445" target="_blank"〉PubMed〈/a〉

    Clonal divergence in Escherichia coli as a result of recombination, not mutation (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-11-25
    Description: Nucleotide sequence analysis was performed on 12 natural isolates of Escherichia coli in four loci located in close proximity on the chromosome. A comparison of gene genealogies indicated that three recombination events have occurred in a subset of the strains (ECOR group A) in the time since their divergence from a common ancestor, while during the same time, no mutational divergence has occurred. The common ancestor of this subset existed no more than 2400 years ago, and recombination was shown to occur at a rate of 5.0 x 10(-9) changes per nucleotide per generation--50-fold higher than the mutation rate. Thus, recombination has been the dominant force driving the clonal divergence of the ECOR group A strains and must be considered a significant factor in structuring E. coli populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guttman, D S -- Dykhuizen, D E -- AI32454/AI/NIAID NIH HHS/ -- GM3020/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Nov 25;266(5189):1380-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolution, State University of New York, Stony Brook 11794.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973728" target="_blank"〉PubMed〈/a〉

    Description: Eleven taxa (including eight heretofore undescribed species) of cellularly preserved filamentous microbes, among the oldest fossils known, have been discovered in a bedded chert unit of the Early Archean Apex Basalt of northwestern Western Australia. This prokaryotic assemblage establishes that trichomic cyanobacterium-like microorganisms were extant and morphologically diverse at least as early as approximately 3465 million years ago and suggests that oxygen-producing photoautotrophy may have already evolved by this early stage in biotic history.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schopf, J W -- New York, N.Y. -- Science. 1993 Apr 30;260:640-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Space Sciences, University of California, Los Angeles 90024, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11539831" target="_blank"〉PubMed〈/a〉

    Calibrating rates of early Cambrian evolution (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-09-03
    Description: An explosive episode of biological diversification occurred near the beginning of the Cambrian period. Evolutionary rates in the Cambrian have been difficult to quantify accurately because of a lack of high-precision ages. Currently, uranium-lead zircon geochronology is the most powerful method for dating rocks of Cambrian age. Uranium-lead zircon data from lower Cambrian rocks located in northeast Siberia indicate that the Cambrian period began at approximately 544 million years ago and that its oldest (Manykaian) stage lasted no less than 10 million years. Other data indicate that the Tommotian and Atdabanian stages together lasted only 5 to 10 million years. The resulting compression of Early Cambrian time accentuates the rapidity of both the faunal diversification and subsequent Cambrian turnover.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bowring, S A -- Grotzinger, J P -- Isachsen, C E -- Knoll, A H -- Pelechaty, S M -- Kolosov, P -- New York, N.Y. -- Science. 1993 Sep 3;261:1293-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth, Atmospheric and Planetary Sciences, Massachusetts Institute of Technology, Cambridge 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11539488" target="_blank"〉PubMed〈/a〉

    Ancient conserved regions in new gene sequences and the protein databases (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-03-19
    Description: Sets of new gene sequences from human, nematode, and yeast were compared with each other and with a set of Escherichia coli genes in order to detect ancient evolutionarily conserved regions (ACRs) in the encoded proteins. Nearly all of the ACRs so identified were found to be homologous to sequences in the protein databases. This suggests that currently known proteins may already include representatives of most ACRs and that new sequences not similar to any database sequence are unlikely to contain ACRs. Preliminary analyses indicate that moderately expressed genes may be more likely to contain ACRs than rarely expressed genes. It is estimated that there are fewer than 900 ACRs in all.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Green, P -- Lipman, D -- Hillier, L -- Waterston, R -- States, D -- Claverie, J M -- New York, N.Y. -- Science. 1993 Mar 19;259(5102):1711-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genetics Department, Washington University Medical School, St. Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8456298" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1993-04-16
    Description: A phylogenetic framework inferred from comparisons of small subunit ribosomal RNA sequences describes the evolutionary origin and early branching patterns of the kingdom Animalia. Maximum likelihood analyses show the animal lineage is monophyletic and includes choanoflagellates. Within the metazoan assemblage, the divergence of sponges is followed by the Ctenophora, the Cnidaria plus the placozoan Trichoplax adhaerens, and finally by an unresolved polychotomy of bilateral animal phyla. From these data, it was inferred that animals and fungi share a unique evolutionary history and that their last common ancestor was a flagellated protist similar to extant choanoflagellates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wainright, P O -- Hinkle, G -- Sogin, M L -- Stickel, S K -- GM 32964/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1993 Apr 16;260(5106):340-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Marine and Coastal Sciences, Rutgers University, New Brunswick, NJ 08903.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8469985" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-01-29
    Description: Geographic expansions are caused by successful innovations, biological or cultural, that favor local growth and movement. They have had a powerful effect in determining the present patterns of human genetic geography. Modern human populations expanded rapidly across the Earth in the last 100,000 years. At the end of the Paleolithic (10,000 years ago) only a few islands and other areas were unoccupied. The number of inhabitants was then about one thousand times smaller than it is now. Population densities were low throughout the Paleolithic, and random genetic drift was therefore especially effective. Major genetic differences between living human groups must have evolved at that time. Population growths that began afterward, especially with the spread of agriculture, progressively reduced the drift in population and the resulting genetic differentiation. Genetic traces of the expansions that these growths determined are still recognizable.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cavalli-Sforza, L L -- Menozzi, P -- Piazza, A -- GM 10452/GM/NIGMS NIH HHS/ -- GM 20467/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1993 Jan 29;259(5095):639-46.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genetics Department, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8430313" target="_blank"〉PubMed〈/a〉

    Evolution of endothermy in fish: mapping physiological traits on a molecular phylogeny (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-04-09
    Description: Mackerels, tunas, and billfishes (suborder Scombroidei and Teleostei) provide an ideal taxonomic context in which to examine the evolution of endothermy. Multiple origins and diverse strategies for endothermy exist among these fish. Here a molecular phylogeny of the Scombroidei has been determined by direct sequencing of a portion of the mitochondrial cytochrome b gene. The distribution of endothermic species within this proposed genealogy indicates that the ability to warm the brain and retina arose independently in three lineages, each time in association with a movement into colder water. This suggests that the evolution of cranial endothermy in fish was selected in order to permit thermal niche expansion and not selected for increased aerobic capacity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Block, B A -- Finnerty, J R -- Stewart, A F -- Kidd, J -- AR40246/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 1993 Apr 9;260(5105):210-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Organismal Biology and Anatomy, University of Chicago, IL 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8469974" target="_blank"〉PubMed〈/a〉

    Geography of end-Cretaceous marine bivalve extinctions (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-05-14
    Description: Analysis of the end-Cretaceous mass extinction, based on 3514 occurrences of 340 genera of marine bivalves (Mollusca), suggests that extinction intensities were uniformly global; no latitudinal gradients or other geographic patterns are detected. Elevated extinction intensities in some tropical areas are entirely a result of the distribution of one extinct group of highly specialized bivalves, the rudists. When rudists are omitted, intensities at those localities are statistically indistinguishable from those of both the rudist-free tropics and extratropical localities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Raup, D M -- Jablonski, D -- New York, N.Y. -- Science. 1993 May 14;260:971-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of the Geophysical Sciences, University of Chicago, IL 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11537491" target="_blank"〉PubMed〈/a〉

    Insect diversity in the fossil record (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-07-16
    Description: Insects possess a surprisingly extensive fossil record. Compilation of the geochronologic ranges of insect families demonstrates that their diversity exceeds that of preserved vertebrate tetrapods through 91 percent of their evolutionary history. The great diversity of insects was achieved not by high origination rates but rather by low extinction rates comparable to the low rates of slowly evolving marine invertebrate groups. The great radiation of modern insects began 245 million years ago and was not accelerated by the expansion of angiosperms during the Cretaceous period. The basic trophic machinery of insects was in place nearly 100 million years before angiosperms appeared in the fossil record.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Labandeira, C C -- Sepkoski, J J Jr -- New York, N.Y. -- Science. 1993 Jul 16;261(5119):310-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Paleobiology, National Museum of Natural History, Washington, DC 20560.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11536548" target="_blank"〉PubMed〈/a〉

    Carnivorous plants: phylogeny and structural evolution (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-09-11
    Description: The carnivorous habit in flowering plants represents a grade of structural organization. Different morphological features associated with the attraction, trapping, and digestion of prey characterize a diversity of specialized forms, including the familiar pitcher and flypaper traps. Phylogenetic analysis of nucleotide sequence data from the plastic rbcL gene indicates that both carnivory and stereotyped trap forms have arisen independently in different lineages of angiosperms. Furthermore, these results demonstrate that flypaper traps share close common ancestry with all other trap forms. Recognition of these patterns of diversification may provide ideal, naturally occurring systems for studies of developmental processes underlying macromorphological evolution in angiosperms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Albert, V A -- Williams, S E -- Chase, M W -- New York, N.Y. -- Science. 1992 Sep 11;257(5076):1491-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1523408" target="_blank"〉PubMed〈/a〉

    Publication Date: 1992-05-01
    Description: Molecular phylogenies of eukaryotic organisms imply patterns of biological and environmental history that can be tested against the geological record. As predicted by sequence comparisons, Precambrian rocks show evidence of episodic increases in biological diversity and atmospheric oxygen concentrations. Nonetheless, complete integration of the two records remains elusive and may require that the earliest macroscopic organisms be recognized as extinct experiments in eukaryotic multicellularity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knoll, A H -- New York, N.Y. -- Science. 1992 May 1;256(5057):622-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Harvard University, Botanical Museum, Cambridge, MA 02138.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1585174" target="_blank"〉PubMed〈/a〉

    The antiquity of oxygenic photosynthesis: evidence from stromatolites in sulphate-deficient Archaean lakes (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-01-03
    Description: The Tumbiana Formation, about 2700 million years old, was largely deposited in ephemeral saline lakes, as judged by the unusual evaporite paragenesis of carbonate and halite with no sulfate. Stromatolites of diverse morphology occur in the lacustrine sediments, some with palimpsest fabrics after erect filaments. These stromatolites were probably accreted by phototropic microbes that, from their habitat in shallow isolated basins with negligible sulfate concentrations, almost certainly metabolized by ozygenic photosynthesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Buick, R -- New York, N.Y. -- Science. 1992 Jan 3;255(5040):74-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Botanical Museum, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11536492" target="_blank"〉PubMed〈/a〉

One of these forms, represented by well-preserved cranial remains from Rudabanya, Hungary, sheds new light on the question of the evolutionary relations among living hominids. This new evidence supports the view that humans have a specific evolutionary relation with chimpanzees, to the exclusion of all other apes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Begun, D R -- New York, N.Y. -- Science. 1992 Sep 25;257(5078):1929-33.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, University of Toronto, Ontario, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1411507" target="_blank"〉PubMed〈/a〉

    Evidence that eukaryotes and eocyte prokaryotes are immediate relatives (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-07-03
    Description: The phylogenetic origin of eukaryotes has been unclear because eukaryotic nuclear genes have diverged substantially from prokaryotic ones. The genes coding for elongation factor EF-1 alpha were compared among various organisms. The EF-1 alpha sequences of eukaryotes contained an 11-amino acid segment that was also found in eocytes (extremely thermophilic, sulfur-metabolizing bacteria) but that was absent in all other bacteria. The related (paralogous) genes encoding elongation factor EF-2 and initiation factor IF-2 also lacked the 11-amino acid insert. These data imply that the eocytes are the closest surviving relatives (sister taxon) of the eukaryotes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rivera, M C -- Lake, J A -- New York, N.Y. -- Science. 1992 Jul 3;257(5066):74-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Biology Institute, University of California, Los Angeles 90024.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1621096" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1992-11-13
    Description: Parasitism is a widespread and diverse life strategy that connects species throughout the animal kingdom. Female parasitoid flies of the genus Ormia must find a specific cricket host on which to deposit their parasitic maggots. To reproduce, female flies must perform the same task as female crickets: find a singing male cricket. These flies have evolved a unique hearing organ that allows them to detect and locate singing male crickets. Through evolutionary convergence, these flies possess a hearing organ that much more resembles a cricket's ear than a typical fly's ear, allowing these parasitoids to take advantage of the sensory ecological niche of their host.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robert, D -- Amoroso, J -- Hoy, R R -- DC00103/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 1992 Nov 13;258(5085):1135-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Neurobiology and Behavior, Cornell University, Ithaca, NY 14853.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1439820" target="_blank"〉PubMed〈/a〉

    Evidence for biased gene conversion in concerted evolution of ribosomal DNA (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-01-18
    Description: Concerted evolution is the production and maintenance of homogeneity within repeated families of DNA. Two mechanisms--unequal crossing over and biased gene conversion--have been the principal explanations of concerted evolution. Concerted evolution of ribosomal DNA (rDNA) arrays is thought to be largely the result of unequal crossing over. However, concerted evolution of rDNA in parthenogenetic lizards of hybrid origin is strongly biased toward one of two parental sequences, which is consistent with biased gene conversion as the operative mechanism. The apparent gene conversions are independent of initial genome dosage and result in homogenization of rDNA arrays across all nucleolar organizer regions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hillis, D M -- Moritz, C -- Porter, C A -- Baker, R J -- New York, N.Y. -- Science. 1991 Jan 18;251(4991):308-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Texas, Austin 78712.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1987647" target="_blank"〉PubMed〈/a〉

    African populations and the evolution of human mitochondrial DNA (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-09-27
    Description: The proposal that all mitochondrial DNA (mtDNA) types in contemporary humans stem from a common ancestor present in an African population some 200,000 years ago has attracted much attention. To study this proposal further, two hypervariable segments of mtDNA were sequenced from 189 people of diverse geographic origin, including 121 native Africans. Geographic specificity was observed in that identical mtDNA types are shared within but not between populations. A tree relating these mtDNA sequences to one another and to a chimpanzee sequence has many deep branches leading exclusively to African mtDNAs. An African origin for human mtDNA is supported by two statistical tests. With the use of the chimpanzee and human sequences to calibrate the rate of mtDNA evolution, the age of the common human mtDNA ancestor is placed between 166,000 and 249,000 years. These results thus support and extend the African origin hypothesis of human mtDNA evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vigilant, L -- Stoneking, M -- Harpending, H -- Hawkes, K -- Wilson, A C -- New York, N.Y. -- Science. 1991 Sep 27;253(5027):1503-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biochemistry and Molecular Biology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1840702" target="_blank"〉PubMed〈/a〉

    Animal choice behavior and the evolution of cognitive architecture (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-08-30
    Description: Animals process sensory information according to specific computational rules and, subsequently, form representations of their environments that form the basis for decisions and choices. The specific computational rules used by organisms will often be evolutionarily adaptive by generating higher probabilities of survival, reproduction, and resource acquisition. Experiments with enclosed colonies of bumblebees constrained to foraging on artificial flowers suggest that the bumblebee's cognitive architecture is designed to efficiently exploit floral resources from spatially structured environments given limits on memory and the neuronal processing of information. A non-linear relationship between the biomechanics of nectar extraction and rates of net energetic gain by individual bees may account for sensitivities to both the arithmetic mean and variance in reward distributions in flowers. Heuristic rules that lead to efficient resource exploitation may also lead to subjective misperception of likelihoods. Subjective probability formation may then be viewed as a problem in pattern recognition subject to specific sampling schemes and memory constraints.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Real, L A -- New York, N.Y. -- Science. 1991 Aug 30;253(5023):980-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of North Carolina, Chapel Hill 27599-3280.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1887231" target="_blank"〉PubMed〈/a〉

    Density-dependent natural selection and trade-offs in life history traits (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-07-26
    Description: Theories of density-dependent natural selection state that at extreme population densities evolution produces alternative life histories due to trade-offs. The trade-offs are presumed to arise because those genotypes with highest fitness at high population densities will not also have high fitness at low density and vice-versa. These predictions were tested by taking samples from six populations of Drosophila melanogaster kept at low population densities (r-populations) for nearly 200 generations and placing them in crowded cultures (K-populations). After 25 generations in the crowded cultures, the derived K-populations showed growth rate and productivity that at high densities were elevated relative to the controls, but at low density were depressed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mueller, L D -- Guo, P Z -- Ayala, F J -- S07 RR07008/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1991 Jul 26;253(5018):433-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of California, Irvine 92717.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1907401" target="_blank"〉PubMed〈/a〉

    Description: Results of a three-year field study of family-level patterns of ecological diversity of dinosaurs in the Hell Creek Formation of Montana and North Dakota show no evidence (probability P 〈 0.05) of a gradual decline of dinosaurs at the end of the Cretaceous. Stratigraphic reliability was maintained through a tripartite division of the Hell Creek, and preservational biases were corrected for by comparison of results only from similar fades as well as through the use of large-scale, statistically rigorous survey and collection procedures. The findings are in agreement with an abrupt extinction event such as one caused by an asteroid impact.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sheehan, P M -- Fastovsky, D E -- Hoffmann, R G -- Berghaus, C B -- Gabriel, D L -- New York, N.Y. -- Science. 1991 Nov 8;254(5033):835-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geology, Milwaukee Public Museum, WI 53233, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11536489" target="_blank"〉PubMed〈/a〉

    Wright's shifting balance theory: an experimental study (1991)

    Details
    Publication Date: 1991-08-30
    Description: Experimental confirmation of Wright's shifting balance theory of evolution, one of the most comprehensive theories of adaptive evolution, is presented. The theory is regarded by many as a cornerstone of modern evolutionary thought, but there has been little direct empirical evidence supporting it. Some of its underlying assumptions are viewed as contradictory, and the existence and efficacy of the theory's fundamental adaptive process, interdemic selection, is the focus of controversy. Interdemic selection was imposed on large arrays of laboratory populations of the flour beetle Tribolium castaneum in the manner described by Wright: the differential dispersion of individuals from demes of high fitness into demes of low fitness. A significant increase in average fitness was observed in the experimental arrays when compared to control populations with equivalent but random migration rates. The response was not proportional to the selection differential: The largest response occurred with interdemic selection every two generations rather than every generation or every three generations. The results indicate that the interdemic phase of Wright's shifting balance theory can increase average fitness and suggest that gene interactions are involved in the observed response.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wade, M J -- Goodnight, C J -- GM22523/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1991 Aug 30;253(5023):1015-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolution, University of Chicago, IL 60637.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1887214" target="_blank"〉PubMed〈/a〉

    Description: Some animals have larger brains than others, but it is not yet known why. Species differences in life-style, including dietary habits and patterns of development of the young, are associated with variation in brain weight, independently of the effects of body weight and evolutionary history. Taken together with behavioral and neuroanatomical analyses, these studies begin to suggest the evolutionary pressures that favor different sized brains and brain components.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harvey, P H -- Krebs, J R -- New York, N.Y. -- Science. 1990 Jul 13;249(4965):140-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Oxford, United Kingdom.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2196673" target="_blank"〉PubMed〈/a〉

    A bangiophyte red alga from the Proterozoic of arctic Canada (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-10-05
    Description: Silicified peritidal carbonate rocks of the 1250- to 750-million-year-old Hunting Formation, Somerset Island, arctic Canada, contain fossils of well-preserved bangiophyte red algae. Morphological details, especially the presence of multiseriate filaments composed of radially arranged wedge-shaped cells derived by longitudinal divisions from disc-shaped cells in uniseriate filaments, indicate that the fossils are related to extant species in the genus Bangia. Such taxonomic resolution distinguishes these fossils from other pre-Ediacaran eukaryotes and contributes to growing evidence that multicellular algae diversified well before the Ediacaran radiation of large animals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Butterfield, N J -- Knoll, A H -- Swett, K -- New York, N.Y. -- Science. 1990 Oct 5;250:104-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Botanical Museum, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11538072" target="_blank"〉PubMed〈/a〉

    Cometary delivery of organic molecules to the early Earth (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-07-27
    Description: It has long been speculated that Earth accreted prebiotic organic molecules important for the origins of life from impacts of carbonaceous asteroids and comets during the period of heavy bombardment 4.5 x 10(9) to 3.8 x 10(9) years ago. A comprehensive treatment of comet-asteroid interaction with the atmosphere, surface impact, and resulting organic pyrolysis demonstrates that organics will not survive impacts at velocities greater than about 10 kilometers per second and that even comets and asteroids as small as 100 meters in radius cannot be aerobraked to below this velocity in 1-bar atmospheres. However, for plausible dense (10-bar carbon dioxide) early atmospheres, we find that 4.5 x 10(9) years ago Earth was accreting intact cometary organics at a rate of at least approximately 10(6) to 10(7) kilograms per year, a flux that thereafter declined with a half-life of approximately 10(8) years. These results may be put in context by comparison with terrestrial oceanic and total biomasses, approximately 3 x 10(12) kilograms and approximately 6 x 10(14) kilograms, respectively.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chyba, C F -- Thomas, P J -- Brookshaw, L -- Sagan, C -- New York, N.Y. -- Science. 1990 Jul 27;249:366-73.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory for Planetary Studies, Cornell University, Ithaca, NY 14853, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11538074" target="_blank"〉PubMed〈/a〉

    Iridium profile for 10 million years across the Cretaceous-Tertiary boundary at Gubbio (Italy) (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-12-21
    Description: The iridium anomaly at the Cretaceous-Tertiary (KT) boundary was discovered in the pelagic limestone sequence at Gubbio on the basis of 12 samples analyzed by neutron activation analysis (NAA) and was interpreted as indicating impact of a large extraterrestrial object at exactly the time of the KT mass extinction. Continuing controversy over the shape of the Ir profile at the Gubbio KT boundary and its interpretation called for a more detailed follow-up study. Analysis of a 57-meter-thick, 10-million-year-old part of the Gubbio sequence using improved NAA techniques revealed that there is only one Ir anomaly at the KT boundary, but this anomaly shows an intricate fine structure, the origin of which cannot yet be entirely explained. The KT Ir anomaly peaks in a 1-centimeter-thick clay layer, where average Ir concentration is 3000 parts per trillion (ppt); this peak is flanked by tails with Ir concentrations of 20 to 80 ppt that rise above a background of 12 to 13 ppt. The fine structure of the tails is probably due in part to lateral reworking, diffusion, burrowing, and perhaps Milankovitch cyclicity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alvarez, W -- Asaro, F -- Montanari, A -- DE-AC03-76SF00098/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 1990 Dec 21;250:1700-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geology and Geophysics, University of California, Berkeley 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11538083" target="_blank"〉PubMed〈/a〉

    Systematic evolution of ligands by exponential enrichment: RNA ligands to bacteriophage T4 DNA polymerase (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-08-03
    Description: High-affinity nucleic acid ligands for a protein were isolated by a procedure that depends on alternate cycles of ligand selection from pools of variant sequences and amplification of the bound species. Multiple rounds exponentially enrich the population for the highest affinity species that can be clonally isolated and characterized. In particular one eight-base region of an RNA that interacts with the T4 DNA polymerase was chosen and randomized. Two different sequences were selected by this procedure from the calculated pool of 65,536 species. One is the wild-type sequence found in the bacteriophage mRNA; one is varied from wild type at four positions. The binding constants of these two RNA's to T4 DNA polymerase are equivalent. These protocols with minimal modification can yield high-affinity ligands for any protein that binds nucleic acids as part of its function; high-affinity ligands could conceivably be developed for any target molecule.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tuerk, C -- Gold, L -- GM 19963/GM/NIGMS NIH HHS/ -- GM 28685/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1990 Aug 3;249(4968):505-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular, Cellular, Developmental Biology, University of Colorado, Boulder 80309.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2200121" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1990-02-23
    Description: According to the endosymbiont hypothesis, mitochondria have lost the autonomy of their prokaryotic ancestors. They have to import most of their proteins from the cytosol because the mitochondrial genome codes for only a small percentage of the polypeptides that reside in the organelle. Recent findings show that the sorting of proteins into the mitochondrial subcompartments and their folding and assembly follow principles already developed in prokaryotes. The components involved may have structural and functional equivalents in bacteria.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hartl, F U -- Neupert, W -- New York, N.Y. -- Science. 1990 Feb 23;247(4945):930-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Physiological Chemistry, University of Munich, Federal Republic of Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2406905" target="_blank"〉PubMed〈/a〉
