Question

Quizplus · Accepted Answer

Partial Replacement Models suggest that modern humans originated in Africa and interbred with premodern populations of Eurasia, resulting in the partial displacement of those populations. This is supported by genetic evidence and the presence of archaic admixture in the genomes of modern humans outside of Africa. Option B is incorrect because it suggests that modern humans from Asia displaced African populations, which is not supported by the evidence. Option C is incorrect because modern humans did not appear until around 200,000 years ago. Option D suggests that Neandertals displaced modern humans, which is also not supported by the evidence. Option E is incorrect because it suggests simultaneous displacement by multiple populations, which is not supported by the data.
