ANATOMY

Detailed explanation-1: -Evolution is a gradual and continuing process of change that occurs over a period of time, due to slight variations in genetic compositions as well as changes in environment, leading to formation of new species.

Detailed explanation-2: -Evolution is the process by which species adapt over time in response to their changing environment.

Detailed explanation-3: -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-4: -The slow gradual change in a species over time is called: Evolution.

Detailed explanation-5: -Charles Darwin understood that evolution was a slow and gradual process. By gradual, Darwin did not mean “perfectly smooth, ” but rather, “stepwise, ” with a species evolving and accumulating small variations over long periods of time until a new species was born.
