Bio 181 - Evolution Origin of Species - correct answer Descent with modification, natural selection, evolutionary adaptation, and evolution are the key components of this work by Charles Darwin. Descent with modification - correct answer Organisms related through descent from an ancestor. Natural selection - correct answer A population can change over time if individuals that possess certain traits leave more offspring than others. It is considered non-random because it deals with whatever is there, selecting the individuals which have the best traits to survive and reproduce. Heritable variation: survival depends partly on inherited traits. Evolutionary Adaptation - correct answer An accumulation of inherited traits that increase an organisms' survival and reproduction in specific environments. Evolution - correct answer Change over time in the genetic composition of a population. Microevolution - correct answer Changes in a single gene in a population over time. Macroevolution - correct answer The formation of new species or groups of related species. Gene pool - correct answer All of the genes present in a given population. Important to evolution because as this narrows, the rate of evolution increases. Darwinian fitness - correct answer The relative likelihood that a genotype will contribute to the gene pool of the next generation as compared with other genotypes. It is a measure of REPRODUCTIVE SUCCESS.
