What is true about microevolution?
iris [78.8K]
Microevolution refers to changes that occur within a single species or group or organisms.  Microevolution, as opposed to macroevolution, occurs in a short period of time. In microevolution, the ancestor and the descendant obviously belong to the same type.  For example, certain pests have evolved in such a way that they become immune to pesticides; the same thing has happened to certain weeds and herbicides. Hope this helps.
