Interesting point in the article regarding the origins of Man. It's only slightly mentioned, but this discovery puts a question mark on the African origins. And the African origins of Man are actually still a subject of debate, because most of the clues supporting that hypothesis were in places in Africa where excavation was easy compared to anywhere else. It's survivorship bias at least as far as I understand the data we have so far. I would not be surprised if we find out one day that humans "appeared" in different locations not directly connected to each other.
Actually both theory turned out to be correct which is the way science sometimes works. Most of our ancestry is traced back to Africa, but the various populations outside of Africa are a mix of African and the various related human species that had been living in the area. For example modern Europeans and East Asian peoples are a hybrid of African humans and Neanderthal human populations [1]. The modern Austronesian peoples (most likely the descendants of the cave painters) are a three way hybrid between African, Neanderthal and the Denisovian humans [2]. I find this all really interesting.
You know, it's good to actually read Wikipedia before linking it. From your link :
> The major competing hypothesis is the multiregional origin of modern humans, which envisions a wave of Homo sapiens migrating earlier from Africa and interbreeding with local Homo erectus populations in multiple regions of the globe. Most multiregionalists still view Africa as a major wellspring of human genetic diversity, but allow a much greater role for hybridization.[12][13]
And no need to put a Strawman about global warming in your answer.
Your own quote still maintains "Africa as a major wellspring of human genetic diversity".
The multiregional "hypothesis" merely puts the "out of Africa" hypothesis earlier in time, i.e. puts back the date at which modern humans migrated out of Africa, rather than disputing that central fact.
There is as yet no evidence for pre-modern humans anywhere but in Africa. Further, genetic evidence we have today does not support interbreeding of modern humans with Homo erectus outside of Africa, which would be necessary for the "multiregional" hypothesis to have any weight.
The exception to this would be if you were to classify Neanderthals or Denisovans as non-human.
Edit: There is now also evidence for a return migration of Europeans back into Africa:
