    Polymorphic butterfly reveals the missing link in ecological speciation (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-11-07
    Description: Ecological speciation occurs when ecologically based, divergent selection causes the evolution of reproductive isolation. There are many empirical examples of this process; however, there exists a poorly characterized stage during which the traits that distinguish species ecologically and reproductively segregate in a single population. By using a combination of genetic mapping, mate-choice experiments, field observations, and population genetics, we studied a butterfly population with a mimetic wing color polymorphism and found that the butterflies exhibited partial, color-based, assortative mate preference. These traits represent the divergent, ecologically based signal and preference components of sexual isolation that usually distinguish incipient and sibling species. The association between behavior and recognition trait in a single population may enhance the probability of speciation and provides an example of the missing link between an interbreeding population and isolated species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875868/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875868/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chamberlain, Nicola L -- Hill, Ryan I -- Kapan, Durrell D -- Gilbert, Lawrence E -- Kronforst, Marcus R -- GM068763/GM/NIGMS NIH HHS/ -- P50 GM068763/GM/NIGMS NIH HHS/ -- P50 GM068763-06/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):847-50. doi: 10.1126/science.1179141.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Faculty of Arts and Sciences Center for Systems Biology, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19892982" target="_blank"〉PubMed〈/a〉

    optix drives the repeated convergent evolution of butterfly wing pattern mimicry (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-07-23
    Description: Mimicry--whereby warning signals in different species evolve to look similar--has long served as a paradigm of convergent evolution. Little is known, however, about the genes that underlie the evolution of mimetic phenotypes or to what extent the same or different genes drive such convergence. Here, we characterize one of the major genes responsible for mimetic wing pattern evolution in Heliconius butterflies. Mapping, gene expression, and population genetic work all identify a single gene, optix, that controls extreme red wing pattern variation across multiple species of Heliconius. Our results show that the cis-regulatory evolution of a single transcription factor can repeatedly drive the convergent evolution of complex color patterns in distantly related species, thus blurring the distinction between convergence and homology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reed, Robert D -- Papa, Riccardo -- Martin, Arnaud -- Hines, Heather M -- Counterman, Brian A -- Pardo-Diaz, Carolina -- Jiggins, Chris D -- Chamberlain, Nicola L -- Kronforst, Marcus R -- Chen, Rui -- Halder, Georg -- Nijhout, H Frederik -- McMillan, W Owen -- New York, N.Y. -- Science. 2011 Aug 26;333(6046):1137-41. doi: 10.1126/science.1208227.
