Vestigial structures - The wings of flightless birds like ostrich, are example of this., Biochemistry - study of nucleic acids and proteins to show evolutionary relationships., Gene Flow - migration, Adaptation - A physical trait that increases an organism's ability to survive in its environment., Mass Extinction - a sudden elimination of a species due to a catastrophic event., Punctuated Equilibrium - rapid evolutionary change., Evolution - Principle of natural selection that explains how beneficial traits should become more common over tome, causing a change in allele frequencies., Descent with modification - Biological change over time that causes descendants to be different from their ancestors., Homologous Structure - Body structures that are similar in orientation, but completely different in function due to organisms living in different environments., Embryology - Study of embryological development in vertebrates that has led to support the theory of common ancestry among vertebrates., Coevolution - when two organisms, such as predator and prey, evolve in response to another., Sexual Selection - when traits that favor reproduction, even though they may decrease an organism's ability to survive, become more common over time., Genetic Equilibrium - When allelic frequencies are stable and unchanging, therefore evolution is not occurring., Speciation - When isolation, such as geographically, causes two populations of organisms to become so different that they can no longer reproduce with each other and create viable offspring., Paleontology - The study of prehistoric life that allows scientists to make connections between current and extinct species., Divergent Evolution - Evolution that results in the formation of homologous structures., Gene Pool - All of the genes available in a population., Gradualism - Slow change in allele frequencies over a long period of time., Natural Selection - Organisms with traits that make them better adapted to their environment will live longer and reproduce more than organisms less adapted to the environment., Anatomy - Study of body structures to provide evidence of evolution., Fossil - Remnants of organisms such as imprints, bones, and feces., Gradual Extinction - Slow elimination of species caused by small environmental changes over extended periods of time., Analogous Structures - Similar body structures, such as fins, due to organisms living in the same environment, not same ancestry., Biogeography - Study of physical distribution of plants and animals., Convergent Evolution - Evolution that results in the formation of analogous structures,
