In my previous post on the subject, I discussed how a new finding of admixture between Homo Sapiens and the Denisovans in Siberia bolster my claims of the northern route (that didn't touch India) of early Homo Sapiens. A new study has now completely discarded the idea of Modern Humans mating with an Erectus branch in SE Asia thus further strengthening the fact that all admixture in Melanesians can only be attributed to their Neanderthal infested northern route than to the Erectus infested southern route.
From the study:
Homo erectus went extinct in Africa and much of Asia by about 500,000 years ago, but appeared to have survived in Indonesia until about 35,000 to 50,000 years ago at the site of Ngandong on the Solo River. These late members of Homo erectus would have shared the environment with early members of our own species, Homo sapiens, who arrived in Indonesia by about 40,000 years ago.
The existence of the two species simultaneously has important implications for models about the origins of modern humans. One of the models, the Out of Africa or replacement model, predicts such overlap. However, another, the multiregional model, which posits that modern humans originated as a result of genetic contributions from hominin populations all around the Old World (Africa, Asia, Europe), does not. The late survival of Homo erectus in Indonesia has been used as one line of support for the Out of Africa model.
However, findings by the SoRT Project show that Homo erectus' time in the region ended before modern humans arrived there. The analyses suggest that Homo erectus was gone by at least 143,000 years ago -- and likely by more than 550,000 years ago. This means the demise of Homo erectus occurred long before the arrival of Homo sapiens.
"Thus, Homo erectus probably did not share habitats with modern humans," said Indriati.
