Document Summary
Chapter 22: descent with modification: a darwinian view of life. Change over time of the genetic composition of a population: 2. ) Descent of modern organisms with modification from preexisting organisms. Evolutionary adaptation: accumulation of inherited characteristics that enhance organisms" ability to survive in specific environments. Bodies of living organisms are modified through the use or disuse of parts. This idea turned out to be wrong. Charles darwin & alfred russel wallace developed the theory independently: darwin voyage of the beagle, wallace naturalist in indonesia. The unequal survival & reproduction of organisms due to environmental forces, resulting in the preservation of favorable adaptations. Process selects from what is available in the gene pool. New characteristics are not created on demand. Inference #1: individuals whose inherited traits give them a higher probability of surviving & reproducing in a given environment tend to leave more offspring than other individuals.
