Natural 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.
Seleção natural (AO 1945: Selecção natural) é o processo proposto por Charles Darwin e Alfred Wallace, os dois responsáveis pela teoria da evolução por seleção natural. A alta fecundidade e a recorrente competição pela sobrevivência em cada espécie geram o pressuposto para esse processo. [ 1 ]
Learn how natural selection is a mechanism of evolution that causes species to change and diverge over time. Explore examples of adaptations, exaptations, survival of the fittest and Darwin's finches.
A seleção natural é um dos mecanismos fundamentais da evolução. Essa teoria evolutiva foi formulada pelo naturalista Charles Darwin (1809-1882). A seleção natural afirma que as características vantajosas de uma população para um determinado ambiente são selecionadas e...
