population : consists of all the individuals of a species that live in a specific geographical area and that can interbreed
natural selection : the process by which individuals that have favorable variations and are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do
adaptation : an inherited trait that has become common in a population because the trait provides a selective advantage
reproductive isolation : condition in which two populations of the same species do not breed with one another because of geographic separation, a difference in mating periods, or other barrier to reproduction
gradualism : the model of evolution in which gradual change over a long period of time leads to species formation
punctuated equilibrium : the model of evolution in which periods of rapid change in species are separated by periods of little or no change
paleontogist : scientists who study fossils
vestigial structure : evidence of an organism's evolutionary past
homologous structure : structures that share a common ancestry
divergence : accumulation of differences between groups
speciation : process by which new species form
subspecies : populations of the same species that differ genetically because of adaptations to different living conditions
