Genetic Drift.

He is right I think let me check

anonymous · Answer

why is that?

anonymous · Answer

Yep he is right :)

Genetic drift is a mechanism of evolution that acts in concert with natural selection to change the characteristics of species over time. It is a stochastic effect that arises from the role of random sampling in the production of offspring. Like selection, it acts on populations, altering the frequency of alleles and the predominance of traits amongst members of a population, and changing the diversity of the group. Drift is observed most strongly in small populations and results in changes that need not be adaptive.
