For example, the planet has experienced ice ages that took place over thousands of years. Domestication is the act of separating a small group of organisms (wolves, in this case) from the main population, and select for their desired traits through breeding.

Some of these changes have happened quickly. For example, the planet has experienced ice ages that took place over thousands of years. Get started for free! In order for evolutionary changes to occur, many generations over thousands to millions of years are often required - meaning, these adaptations dont happen overnight!

Adaptation refers to a mutation or genetic change that enables an organism such as an animal. There are 4 mechanisms of evolution (how evolution happens): Natural selection is a process that favors heritable traits that increase the survival chances of an organism, allowing the organism to reproduce more! Suggested answer: Natural selection is the process by which favorable traits are passed down through different generations of a species in order to adapt and likely survive within the changing environment. - Bright mice produced fewer offspring than dark mice, so the bright mice became outnumbered within days. When multiple environments favor the existence of a trait, these beneficial traits can pop up through mutation and spread throughout their individual populations completely independently. variation. compare wolf and dog DNA.
