Speciation vs natural selection
WebDifference Between Natural Selection And Speciation Natural selection and speciation are two examples of how biodiversity can be expanded within an ecosystem. Natural … WebSympatric speciation is the evolution of a new species from a surviving ancestral species while both continue to inhabit the same geographic region. In evolutionary biology and biogeography, sympatric and sympatry are terms referring to organisms whose ranges overlap so that they occur together at least in some places. If these organisms are closely …

WebNatural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift. Darwin's grand idea of evolution by natural selection is relatively simple but often misunderstood. To see how it works, imagine a population of beetles: There is variation in traits. For example, some beetles are green and some are WebA large number of mathematical models have been developed that show how natural and sexual selection can cause prezygotic isolation to evolve.
