CARTA April 29, 2016 lectures on human evolution The CARTA lectures on human evolution included lectures from Joshua Akey from the University of Washington, Kay Prà ¼fer from the Mark Planck Institute for Evolutionary Anthropology, and Tony Capra from Vanderbilt University. Each of the speakers talked in some detail about the interbreeding of Neandertals, Denisovans, and modern humans. However, each speaker talked about a different aspect of the breeding. Akey spoke about Neandertal and Denisovan DNA in modern humans and their effects. Prà ¼fer discussed the interbreeding of Neandertals and Denisovans and how it affects the relationship of Neanderthals and Denisovans to modern humans. Lastly, Capra spoke on the phenotypic effects of Neandertal DNA in modern humans. Akey opened his lecture with a question: how widespread were ancient introgression events? He sought to answer how long ago did archaic humans and modern humans interbred and how many times did they interbreed. Akey mentioned that for a while there was a debate whether hybridization even occurred between archaic humans and modern humans. This was an ongoing debate until fairly recently when there was data that was obtained through sequencing the Neandertal and Denisovan genomes that supported that archaic humans did indeed mate with other modern humans. He mentioned that a problem with sequencing is that it can be hard to find a suitable specimen that has been well preserved. Akey and his student wanted to excavateShow MoreRelatedSimilarities And Differences Between Rusingoryx And Hadrosaur Dinosaurs933 Words   |  4 Pagesspecies is a surprising example of what’s called convergent evolution.† (Strickland, Feb.4, 2016, para. 2).

Who were our ancestors and what made them so different from us? It is debated if A. africanus or Australopithecus afarensis is the direct ancestor of the genus Homo. Through critical evaluation of the features of the skeleton, dentition, and use of bipedality, it is evident that A. africanus is a direct ancestor to modern humans while possessing features from both humans and hominins. What makes A. africanus more human-like than other australopithecinesRead MoreTechnology And Its Impact On Society966 Words   |  4 Pageswords!

The evolution of many facets of government in addition to naturally occurring disasters, such as crop failure, created a crisis mentality. This shaped the framework for what was to become the witch-hunts thatRead MoreSocietal Factors Of Scientific Research Essay1207 Words   |  5 PagesBenjamin Moy TA: Michelle Gertz Discussion: Friday 3 PM 16 December 2016 Societal Factors in Scientific Research Science has clearly influenced the larger society from both a social and technological standpoint.
