Document Summary
Analogous: showing similarity of function but different origins. Describe the factors that led darwin to his theory of evolution by natural selection. Summarize five different types of evidence of evolutionary change. Know the difference between homologous and analogous traits. Provide examples of three types of homologies. Group of related organisms that share a distinctive form. Among species that reproduce sexually, members of the same species are capable of interbreeding to produce viable and fertile offspring. A group of organisms belong to the same biological species if they are (actually or potentially) capable of interbreeding to produce fertile offspring. A heritable change in one or more characteristics of a population or species across many generations. Viewed on a small scale relating to changes in a single gene in a population over time = microevolutionary change. Viewed on a larger scale relating to formation of new species or groups of species = macroevolutionary change.
