Detailed explanation-1: -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-2: -Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes.
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: -Evolutionary biologists often define ‘evolution’ as any change in a population’s genetic composition over time.
Detailed explanation-5: -Evolution: All species of living organisms, from bacteria to baboons to blueberries, evolved at some point from a different species. Although it may seem that living things today stay much the same, that is not the case-evolution is an ongoing process.
