The process of evolution drives changes in living organisms from "summary" of Human Biology by Cecie Starr,Beverly McMillan
Evolution is the driving force behind changes in living organisms. It is a process that occurs over time, leading to the development of new traits and characteristics in populations. This process is driven by natural selection, where individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to future generations. One of the key components of evolution is genetic variation. This variation arises from mutations, genetic recombination, and genetic drift. Mutations are random changes in an organism's DNA that can create new traits. Genetic recombination occurs when genes are shuffled during reproduction, leading to new combinations of traits. Genetic drift refers to the random changes in gene frequencies that occur in small populations. Natural selection acts on this genetic...
