Studying evolution is an excellent way for students to learn about the process of scientific inquiry. Evolution offers countless and diverse examples of the ways scientists gather and analyze information, test competing hypotheses, and ultimately come to a consensus about explanations for natural phenomena.
Evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms ' observable traits.enetic drift is a cause of allelic frequency change within populations of a species. Alleles are different variations of specific genes. They determine things like hair color, skin tone, eye color and blood type; in other words, all the genetic traits that vary between individuals.
