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 WebLa selección natural fue propuesta por Darwin como medio para explicar la evolución biológica. Esta explicación parte de tres premisas; la primera de ellas es que el rasgo sujeto a selección debe ser heredable. La segunda sostiene que debe existir variabilidad del rasgo entre los individuos de una población.

WebNATURAL SELECTION OPEN SAVEDSAVE Natural Selection In this simulation you will investigate populations of birds living on an island. You will begin by selecting three birds that will represent phenotypes for several traits in one population that lives in the southwest portion of the island.
