biogeography : the branch of biology that deals with the geographical distribution of plants and animals.
evolution : the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.
fossils : the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock.
founder effect : the reduced genetic diversity that results when a population is descended from a small number of colonizing ancestors.
gene pool : the stock of different genes in an interbreeding population.
homology : similarity in sequence of a protein or nucleic acid between organisms of the same or different species.
microevolution : evolutionary change within a species or small group of organisms over a short period of time.
natural selection : the process whereby organisms better adapted to their environment tend to survive and produce more offspring.
population : a community of animals, plants, or humans among whose members interbreeding occurs.
hardyweinberg formula : p squared plus two pq plus q squared equals 1
hardyweinberg equilibrium : a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
gene flow : the transfer of alleles of genes from one population to another.
genetic drift: an overall shift of allele distribution in an isolated population, due to random fluctuations in the frequencies of individual alleles of the genes.
darwinian fitness : describes how successful an organism has been at passing on its genes.
directional selection : a mode of natural selection in which a single phenotype is favored, causing the allele frequency to continuously shift in one direction.
diversifying selection : increases the variation in a population by favoring the extreme individuals.
evolutionary adaptation : when something evolves to adapt to their surroundings so they don't die out.
fossil record : the totality of fossilized artifacts and their placement within the earth's rock strata. It provides information about the history of life on earth.
bottleneck effect : happens when the size of a population or even an entire species is suddenly reduced, with lasting effects on at least one generation.
stabilizing selection : a type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value.
stabilizing selection : a type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value.
