WebSo we have reduced gene flow, but not total isolation. This may or may not be sufficient to cause speciation. Speciation would probably also require different selective pressures at opposite ends of the range, which would alter gene frequencies in groups at different ends of the range so much that they would not be able to mate if they were ...

WebThere are four key mechanisms that allow a population, a group of interacting organisms of a single species, to exhibit a change in allele frequency from one generation to the next. These are evolution by: mutation, genetic drift, natural selection, and gene flow. Each type of evolution can be characterized by how it affects fitness, adaptation ...

WebSympatric speciation is the evolution of a new species from a surviving ancestral species while both continue to inhabit the same geographic region.
