Document Summary
Decent with modification: a darwinian view of life. Evolution: two main ideas: change over time of the genetic composition of a population, decent of modern organisms with modification from preexisting organism. Evolutionary adaptation: accumulation of inherited characteristics that enhance organisms" ability to survive in specific environments. Use and disuse: bodies of living organisms are modified through the use or disuse of parts. Inheritance of acquired characteristics: these modifications are inherited by offspring. These ideas turned out to be wrong. 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. New characteristics are not created on demand. Think about the 100 m dash track and field competition. Selective breeding of organisms to encourage the occurrence of desirable traits. Analogous to natural selection (insert broccoli figure) Concept 22. 3 evolution i supported by an overwhelming amount of scientific evidence.
