Document Summary
Use and disuse: bodies of living organisms are modified through the use or disuses of parts. Inheritance of acquired characteristics: these modifications are inherited by offspring. 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. Evolution has two main ideas: change over time of the genetic composition of a population, decent of modern organisms with modification from preexisting organisms. Accumulation of inherited characteristics that enhance organisms" ability to. Think about the 10-m dash track and filed competition. Selective breeding of organisms to encourage the occurrence of desirable traits. Concept 22. 3: evolution is supported by an overwhelming amount of scientific evidence. Homologous: structures or other attributes in different species that resemble each other of common ancestry. Analogous: structures that are similar in function but not in structure and developmental and evolutionary origin. Humans, cats, whales, and bats all have homologous structures.
