Chapter 15: 1. Evolution: the change in the inherited traits of a population of organisms through successive generations. 2. Microevolution: the occurrence of small-scale changes in allele frequencies in a population, over a few generations, also known as "change below the species level". 3. Macroevolution: a scale of analysis of evolution in separated gene pools . 4. Empirical: Depending upon experience or observation alone, without due regard to science and theory; 5. Taxonomy: The science of finding, describing, classifying, and naming organisms , including the studying of the relationships between taxa and the principles underlying such a classification. 6. Binomial Nomenclature: This is the way in which organisms have been classified over time , with most organisms being described in either greek or latin . Although latin is now a defunct language , classification of organisms are still being classified with this language . An example of the language used is yucca filamentosa, a plant of the yucca genus and the unique filamentosa species . 7. Comparative Anatomy: The comparative study of animal structure with regard to homologous organs or parts . 8. Catastrophism: the idea that Earth has been affected in the past by sudden, short-lived, violent events, possibly worldwide in scope. 9. Uniformitarianism: Of, pertaining to, or designating, the view or doctrine that existing causes , acting in the same manner and with essentially the same intensity as at the present time , are sufficient to account for all geological changes .

10. Punctuated Equilibrium: A theory that describes an evolutionary change happening rapidly and in brief geological events in between the long periods of stasis (or equilibrium ). 11. Biogeography: The study of the distribution of different species of organisms around the planet and the factors that influenced that distribution . 12. Population: A group of organisms of one species that interbreed and live in the same place at the same time. 13. Selection: certain traits or alleles of genes segregating within a population. 14. Natural Selection: A process in nature in which organisms possessing certain genotypic characteristics that make them better adjusted to an environment tend to survive, reproduce, increase in number or frequency , and therefore, are able to transmit and perpetuate their essential genotypic qualities to succeeding generations . 15. Artificial Selection: More commonly known as
