SUNY-Albany biologist Caro-Beth Stewart and NYU anthropologist Todd R. Disotell have proposed... that the ancestor of humans and the living African apes evolved in Eurasia, not Africa. This controversial new model for the evolution of humans and apes is the cover story of the July 30th issue of Current Biology. Stewart and Disotell describe their theory in an article entitled "Primate evolution -- in and out of Africa." ...The fossil record indicates that apes were present in Europe and Western Asia during the Miocene Era, from about 8 to 17 million years ago. Ancestors of these ape species must have moved between the African and Eurasian land masses during their evolutionary history... Based on a synthetic analysis of molecular, fossil, and biogeographical data for the primates, Stewart and Disotell propose instead that the lineage leading to the common ancestor of all living apes dispersed out of Africa about 20 million years ago (during the early Miocene) and then speciated into the greater and lesser Ape lineages in Eurasia. Within the past 10 million years, one of the great ape species dispersed back into Africa. This lineage eventually speciated into gorillas, chimpanzees and humans... Stewart and Disotell's research is based on parsimony analysis... the model which involves the fewest evolutionary events to explain the data... The problem with the traditional model, say Disotell and Stewart, is that it calls for at least six separate dispersal events out of Africa to account for all living and extinct hominoid species in Eurasia. Disotell and Stewart's model... requires only two.
