Detailed explanation-1: -Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes.
Detailed explanation-2: -Evolution: Evolution consists of changes in the heritable traits of a population of organisms as successive generations replace one another. It is populations of organisms that evolve, not individual organisms.
Detailed explanation-3: -Evolution is the process by which species adapt over time in response to their changing environment.
Detailed explanation-4: -Definition. Evolutionary change is the heritable change in populations and species over time, due to mechanisms such as natural selection, random genetic drift, and sexual selection.
Detailed explanation-5: -The genetic variation of an entire species is often called genetic diversity. Genetic variations are the differences in DNA segments or genes between individuals and each variation of a gene is called an allele.
