Detailed explanation-1: -Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.

Detailed explanation-2: -Evolution: Evolution consists of changes in the heritable traits of a population of organisms as successive generations replace one another.

Detailed explanation-3: -The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

Detailed explanation-4: -Evolution is the change in characteristics of populations of organisms over time. Changes can be small, for example, a small change in body size or a change in the color of a species’ fur.
