The Multiregional Evolution Model (which argues that modern Homo sapiens could have evolved/appeared in several different parts
of the world) states that modern Homo sapiens: a. evolved in Africa and migrated into the rest of the world
b. evolved only in northern and eastern Europe and migrated into the rest of the world
c. evolved locally in Europe, Africa, and Asia from population of archaic Homo sapiens
d. evolved in North, Central, and South America and migrated into the rest of the world
The evolution of modern humans or Homo sapiens has been explained by various theories like the Out-of-Africa model, Assimilation model and Multiregional Continuity model.
The Multiregional Evolution Model proposed by Wolpoff suggests that modern human species have been evolved from the archaic humans like <em>Homo erectus</em> which used to hunt and had cultures. The <em>Homo sapiens</em> developed throughout the different parts of the world like Europe, Asia, and Africa in which gene flow occurred only on the borders of these regions.
When there is a change in the frequency of genes in a small population due to chance event as a result of which a few alleles disappear from the population, is known as genetic drift.
In the given situation, the population size is small i.e. 25 and 40 respectively and in both these populations, it can be seen that one of the population only has allele A whereas the other has allele a, and because of this it can be concluded that this situation must have arisen due to genetic drift.
The populations got established due to random sampling and then the progenies inherited only the alleles of the organism that reproduced and thus, the frequency of the other allele decreased and this is merely a chance event.
Habitat Enclosure is like a cage Platform is a raised surface Habitat is the natural home for an organism A biome is basically a forest. Its where there a lot of plants and animals
