Beschreibung: From the rust-brown sediments of long-dried streams that once rumbled through the rugged terrain of Canada’s Ellesmere Island, a team of paleontologists unearthed in 2004 fossils of a 375 million-year-old species of fish that may have nearly crossed an evolutionary Rubicon. Named Tiktaalik roseae, the now-extinct animal has come to...

Beschreibung: For the last 150 y scholars have focused upon the roles of intentional breeding and genetic isolation as fundamental to understanding the process of animal domestication. This analysis of ethnoarchaeological, archaeological, and genetic data suggests that long-term gene flow between wild and domestic stocks was much more common than previously...

Beschreibung: Recent increases in archaeobotanical evidence offer insights into the processes of plant domestication and agricultural origins, which evolved in parallel in several world regions. Many different crop species underwent convergent evolution and acquired domestication syndrome traits. For a growing number of seed crop species, these traits can be quantified by...

Beschreibung: In his 1933 inaugural address to the American people, President Franklin Roosevelt attempted to rouse the nation out of the stultifying Depression with his famous aphorism on fear as a self-fulfilling end. Decades later, a scientific understanding of fear continues to remain elusive, despite the unraveling of brain circuits triggered...

Beschreibung: Laser imaging reveals long-lost traces of ancient civilizations hidden beneath tropical forest canopies. Archaeologists are known for getting their hands—and everything else—dirty. However, in April 2012, archaeologist Damian Evans boarded a helicopter and spent hours being flown over the dense foliage surrounding Angkor Wat, Cambodia’s legendary complex of ancient stone...

Beschreibung: DNA sequences called telomeres, located at the ends of chromosomes, fold into compact structures called G-quadruplexes. These structures are named for the four repeated sequences of the nucleotide guanine that characterize telomeric DNA and shape the folding of the quadruplex. Cynthia J. Burrows, a chemist at the University of Utah...

Yet infants below the age of one recognize and attempt to imitate the sounds of human speech even before they begin to grasp the meaning of words or produce them. Around 12...

Beschreibung: With the advent of rapid genome sequencing, the view of the human genome as a vast desert dotted with far-flung oases of functional genes has contended with a growing appreciation of the role of regulatory sequences in shaping gene expression. The fraction of the human genome’s noncoding component that can...

Beschreibung: Many animal species have created their own pharmacies from ingredients that commonly occur in nature. Birds, bees, lizards, elephants, and chimpanzees all share a survival trait: They self-medicate. These animals eat things that make them feel better, or prevent disease, or kill parasites like flatworms, bacteria, and viruses, or just...
