I've had the pleasure of listening to two talks presented by Dr Michael Hammer at the Who Do You Think You Are? Live family history show in London in recent years. He is always a very entertaining speaker and has the knack of explaining difficult concepts in an easy-to-understand way. An after dinner talk that Dr Hammer presented at the African Genetics International Conference earlier this year has now been posted to YouTube. The talk is entitled "Beyond Eden: The Significance of Archaic Admixture in Africa". He explains the latest theories on early human origins and looks at the contributions made to our gene pool by archaic Neanderthal and Denisovan populations. Enjoy!
