Evolution and adaptation: change over time of the genetic composition of a population, descent of modern organisms with modification from preexisting organisms. Evolutionary adaptation: accumulation of inherited characteristics that enhance organisms ability to survive in specific environments. Evolution by natural selection: darwin and wallace developed the theory independently, darwin voyage of the beagle, wallace naturalist in indonesia. The unequal survival and reproduction of organisms due to environmental forces, resulting in the preservation of favorable adaptations. Process selects from what is available in the gene pool. Obervations: individuals in a population vary in their heritable traits, organisms more offspring than the environment can support. Inferences: individuals that are well suited to their environment tend to leave more offspring than other individuals, over time, favorable traits accumulate in the population. Artificial selection: selective breeding of organisms to encourage the occurrence of desirable traits, analogous to natural selection.
