SciLifeLab The Svedberg seminar series, Jerry Coyne
Monday October 12
Department of Ecology and Evolution, Biological Sciences Collegiate Division, University of Chicago, USA
Jerry A. Coyne is a Professor in the Department of Ecology and Evolution at the University of Chicago. He received a B.S. in Biology from the College of William and Mary and a Ph.D. in evolutionary biology at Harvard University. Coyne’s work has been largely concerned with the genetics of species differences, aimed at understanding the evolutionary processes that produce new species. He has written 115 scientific papers and more than 130 popular articles, book reviews, and columns, as well as a scholarly book about his research area-Speciation, co-authored with H. Allen Orr, a trade book about the evidence for evolution-Why Evolution is True, which was a New York Times bestseller, and the new book Faith vs. Fact: Why Science and Religion are Incompatible.
Two flies on an island: twenty years of work on sibling species of Drosophila
What are the genetic and ecological changes associated with the formation of a new species? In this talk I summarize two decades of work on the sister species D. santomea (endemic to the African oceanic island of Sao Tome) and D. yakuba, which lives on the island but is also widespread in sub-Saharan Africa. I will describe the morphological, genetic and physiological changes accompanying this recent speciation event, evidence for “reinforcement” (the increase of reproductive isolation via natural selection in areas where the species coexist) and recent studies of the degree of genic introgression in laboratory “hybrid swarms” of species as these swarms evolve over time.
