QUE SIGNIFIE MICROEVOLUTION EN ANGLAIS
Microévolution
La microévolution est le changement des fréquences alléliques qui se produisent au fil du temps dans une population. Ce changement est dû à quatre processus différents: la mutation, la sélection, le flux génétique et la dérive génétique. La génétique des populations est la branche de la biologie qui fournit la structure mathématique pour l'étude du processus de microévolution. La génétique écologique se préoccupe d'observer la microévolution dans la nature. Typiquement, les cas d'évolution observables sont des exemples de microévolution; Par exemple, les souches bactériennes qui ont une résistance aux antibiotiques. La microévolution au fil du temps peut conduire à la spéciation ou à l'apparition d'une nouvelle structure, parfois classée comme macroévolution. Contrairement aux revendications des créationnistes, cependant, la macro et la microevolution décrivent des processus fondamentalement identiques sur différentes échelles de temps.
