Define the Replacement Model (complete and partial): Define the Multiregional Model Solution Ques-1: Complete replacement model: this models is defined as the evolution of anatomically modern human populations in Europe & Asia due to migration of African modern populations within last 200,000 years, this events is described as a biological speciation event. Partial Replacement Models: it is defined as the model in which there has no biological speciation occurred but minor interbreeding occurred between emigrating populations of African & resident premodern human beings.

1. Define the Replacement Model (complete and partial):
Define the Multiregional Model
Solution
Ques-1:
Complete replacement model: this models is defined as the evolution of anatomically modern
human populations in Europe & Asia due to migration of African modern populations within last
200,000 years, this events is described as a biological speciation event.
Partial Replacement Models: it is defined as the model in which there has no biological
speciation occurred but minor interbreeding occurred between emigrating populations of African
& resident premodern human beings
