No human, antelope or gelada/baboon evolution in Africa - only hybridization and phenotyping.
Svante Pääbo (Max Planck Institute) thinks something happened with human intelligence some 50,000 bp. Peter Klevius has since 2010-2012 stated that this was due to 1) a new brain setup from the cradle of evolution, i.e. SE Asian volatile archipelago (see postings below) which 2) then entered the mainland and filled big skulled northern Homos (compare art and dna from the Denisova cave). Peter Klevius reminder to other anthropologists (and especially to afropologists): Earth isn't flat anymore! The insane idea that a moving target like Australopithecus, Homo habilis, Homo erectus, Homo sapiens etc. could have been hiding on the Eurasian peninsula called Africa for some million years to reach speciation, will become the laughing stock of future anthropologists. Everyone agrees that antelopes came out of Eurasia into Africa. However, because baboons have become sort of a love child of afropologists as a model for the senseless "human evolution in Africa...
