Maybe the out of Arica theory should be revisited? Post the Zanclean flood when the Mediterranean basin was subtropical it appears there were hominids "all over creation." That is to say Australia, Kenya, Philippines and even a Homo Erectus version in India. Due to the subtropical climate and the below sea Mediterranean basin who is to say that no proto-human in that basin did not run north-south, and east?
- opportune 8y agoJust because there were hominins outside of africa millions of years ago doesn't mean modern humans descended from them. For example, we have long known that Homo Erectus left Africa millions of years ago. What we do not have evidence of are direct ancestors of anatomically modern humans originating outside of Africa.
- patrickg_zill 8y agoThe out of Africa theory has been overblown for a long time. See as just one example, https://www.scientificamerican.com/article/is-the-out-of-africa-theory-out/ https://www.scientificamerican.com/article/is-the-out-of-afr...
- hyperpape 8y agoTo me, that article reads like it concerns the ancestors of Neanderthals. Am I misreading it?
- twblalock 8y agoMassive amounts of genetic evidence have been discovered since that article was published and the out of Africa theory still holds up.
- patrickg_zill 8y agoPlease cite some of the sources of the information that you claim is massively out there...
- twblalock 8y agoThe out of Africa theory is overwhelmingly supported by genetic evidence. A multi-origin hypothesis is basically impossible to support at this point. What is now happening is that the out of Africa theory is absorbing new facts: - How many different migrations of homo sapiens out of Africa have there been? (probably several) - Did any groups who spent time in Europe migrate back to Africa and contribute new genes to the African gene pool (likely) - Did homo sapiens who left Africa encounter and breed with other hominin species? (definitely, and those other species also originated in Africa) David Reich's book from last year, "Who We Are and How We Got Here", covers a lot of the recent discoveries.
- flukus 8y agoI don't think everyone here is using the same definition of "out of Africa" here. There pretty much no doubt the hominids in general and modern humans came from Africa. But subspecies like denisova and neanderthal evolved outside of Africa (probably). Most modern humans are from Africa with multi-regional mixins, those mixins themselves were African origin if you go back far enough. It's all a game of how far you want to go back.
- coldacid 8y agoThere have almost certainly been multiple migrations out of Africa, per the Sahara pump theory.
