How Does Gene Flow Cause Evolution
The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism’s DNA that create diversity within a population by introducing new alleles.

What’s an example of convergent evolution?

An example of convergent evolution is the similar nature of the flight/wings of insects, birds, pterosaurs, and bats. … Structures that are the result of convergent evolution are called analogous structures or homoplasies; they should be contrasted with homologous structures, which have a common origin.

How do pollinators contribute to the gene flow?

In cities, pollinator foraging is often sufficient to maintain gene flow between fragmented patches. … Pollinators that move long distances have been documented to maintain population connectivity, limit inbreeding and reduce genetic differences among populations (Ehrlich and Raven, 1969; Lenormand, 2002).
