Final answer:
The Multiregional Evolution hypothesis (Extreme model 2) proposes that Homo sapiens evolved from Homo erectus in several regions simultaneously.
Step-by-step explanation:
The Multiregional Evolution hypothesis (Extreme model 2) suggests that Homo sapiens evolved from Homo erectus in several places around the same time. This model proposes that different populations of Homo erectus in various regions underwent parallel evolutions that led to the emergence of Homo sapiens. It suggests that modern humans did not solely originate from a single African population, but rather from multiple populations across different regions.
