Convergent Evolution - The evolution toward similar characteristics in unrelated species, Divergent Evolution - Closely related species evolve in different directions and become increasingly different., Coevolution - When 2 or more species evolve in response to changes in each other., Adaptive Radiation - Diversification of  1 ancestral Species into many descendent species., Gradualism - The concept that species evolve very slowly over long periods of time., Punctuated Equilibrium - Bursts of evolutionary activity followed by long periods of stability., Common Ancestor - The origin of related species., Adaptation - A change allowing for better survival rates and reproduction., Evolution - Change in a population over time., Natural selection - nature chooses traits be suited for survival , Population - a group of one type of species in an area., Phenotype - observable, physical characteristics., Genotype - Combination of alleles (DNA), Genetic Variation - different genes among organisms in a population., Variation - genotypic and phenotypic differences among organisms of the same species. Beneficial phenotypes will be selected in natural selection, Heritability - the relationship between phenotypes and their genetic contribution. Traits that can be developed in a population, rather than just an individual, contribute to evolution., Gene Flow - is the random transfer of alleles from one population to another, gene migration., Genetic Drift - is the change of allele frequency within one population. It is a random event, decreasing the population size and affecting the gene pool., Behavioral Isolation - Reproduction does not occur between similar species due to differences in mating behavior., Temporal Isolation - Reproduction does not occur between similar species because they mate at different times., Geographic Isolation - Populations are separated by water or land and evolve differently, increasing biodiversity.,
