An informative article at: http://www.theoccidentalobserver.net/2017/07/28/anthropologys-obsession-with-african-origins/, has made the argument that the “out-of-Africa” paradigm in anthropology, has been advanced primarily because of cultural Marxist egalitarian ideology, as the author Austin Layard, observes:
“ Largely due to the anti-racist politicization of anthropology, the currently accepted evolutionary paradigm is that Africa was the source of an intellectual watershed event sometime between 100,000 to 50,000 years ago, and that it was only a matter of time before this new breed of clever Africans spread out and replaced all the dim-witted archaic human populations in the rest of the world, such as Neanderthals. (As used here, the term ‘racist’ refers to views that race and racial differences are a legitimate variable in research on humans, with none of the usual negative connotations found in the popular and scientific literature.)
