Quizplus · Accepted Answer

This is the commonly accepted definition of evolution. It refers to the process by which populations of organisms change over time through the gradual accumulation of small genetic changes. The key factor driving evolution is natural selection, which favors those traits that increase an organism's chances of survival and reproduction. Over many generations, these favorable traits become more common in the population, leading to the formation of new species and the diversification of life on Earth.
