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: -What is evolution? Biological evolution refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms’ genes mutate and/or recombine in different ways during reproduction and are passed on to future generations.

Detailed explanation-3: -Evolution is the process by which species adapt over time in response to their changing environment.

Detailed explanation-4: -Evolution can be seen as a two-step process. First, hereditary variation takes place; second, selection is made of those genetic variants that will be passed on most effectively to the following generations.

Detailed explanation-5: -Evolution is the change in inherited characteristics or traits in a population of organisms over many generations. The mechanism that best explains evolution is a phenomenon known as natural selection.
