WN@TL - The Evolution of the Chicken. Mark Berres. 2018.02.28

The domestication sequence of mammals such as dogs and farm animals is relatively well known. However, the origin of the domestic chicken has been debated since Darwin’s day and stretches back into evolutionary time to the mysterious origin of birds themselves. Of all the bird diversity that exists today, only four species — collectively called junglefowl — are considered possible ancestors of the modern chicken. In his talk, Berres will explore this story, beginning by investigating the origins of birds (dinosaurs never really went extinct), along with where and when chickens were first domesticated. He will then assess how the cultural diffusion of domestic chickens has influenced human history and present some of his work with Vietnamese red junglefowl, a direct ancestor of the not-so-ordinary chicken. About the Speaker Berres earned his bachelor’s degree at the University of Minnesota in Saint Paul and his doctorate at the University of Wisconsin–Madison. After completing a postdoc in genomic sciences at UW–Madison, he accepted a faculty position on campus and taught Ornithology, Birds of Southern Wisconsin, and Avian Physiology from 2005 to 2016. He now conducts bioinformatics research in the Advanced Genome Analysis Resource Center at the UW’s Biotechnology Center. His ornithological experience dates back to 1990 and includes international and domestic work with passerines and nonpasserines — especially manakins, hummingbirds, and red junglefowl. He can often be found mist-netting birds at the Biocore Prairie Bird Banding Observatory on Saturday mornings during the summer and fall months.
