Individuals that are well suited to their environment tend to leave more offspring than other individuals: and overtime, favorable traits accumulate in the population. Artificial selection: selective breeding of organisms to encourage the occurrence of desirable traits, analogous to natural selection, concept 22. 3 evolution is supported by an overwhelming amount of scientific evidence, figure 22. 14.
