Detailed explanation-1: -Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. For example, a rabbit can’t choose to have a different fur color.

Detailed explanation-2: -A population has genetic variations, possibly due to mutations. Favorable variations may allow an organism to be better adapted to its environment and survive to reproduce.

Detailed explanation-3: -This happens by the process of natural selection. By natural selection, the nature of the species gradually changes to become adapted to the niche. If a species becomes very well adapted to its environment, and if the environment does not change, species can exist for a very long time before they become extinct.

Detailed explanation-4: -The three basic types of adaptations, based on how the genetic changes are expressed, are structural, physiological and behavioral adaptations.

Detailed explanation-5: -An adaptation is a characteristic that helps an organism to survive in its environment.
