As continents drift apart, it becomes hard for a population to
mingle freely due to geological separation.
This restricts the gene flow in the once homogenous population hence resulting in the allopatric
speciation of the separated groups of the population. Also, as the continents drift, their climate changes and so does the flora and fauna in the process of
adaptation.
