| the mechanism for evolution | ||
| individuals with beneficial heritable traits leave more offspring, and the frequency of such traits in a population increases over generations | ||
| the branch of biology that names and classifies organisms; originated in the work of Linnaeus | ||
| remnants or impressions of past organisms | ||
| the study of fossils | ||
| Cuvier maintained that the differences he observed in the fossils found in different strata were the result of locat catastrophic events such as floods or drought and were not indicative of evolution | ||
| the idea that immense change is the cumulative result of slow but continuous processes; proposed by Hutton and Lyell | ||
| humans have modified other species over many generations by selecting and breeding individuals that posses desired trait | ||
| similarity in characteristics resulting from a shared ancestry | ||
| represent variations on a structural theme that was present in their common ancestry | ||
| structures of marginal importance to the organism | ||
| the study of the past and present distribution of species | ||
| plants and animals found nowhere else in the world | ||
| how most fossils are formed; sand and mud that settles to the bottom of seas, lakes, and marshes. | ||
| Lyell's idea that geologic processes have not changed throughout Earth's history | ||
| a phrase that condenses Darwin's view of life | ||
| emphasizes the extensive genetic variation within populations and recognizes the importance of quantitative characters | ||
| a comprehensive theory of evolution that integrates discoveries and ideas from many different fields, including paleontology, taxonomy, biogeography, and, of course, population genetics | ||
| a localized group of individuals belonging to the same species | ||
| group of populations whose individuals have the potential to interbreed and produce fertile offspring in nature | ||
| total aggregate of genes in a population at any one time | ||
| the frequencies of alleles and genotypes in a population's gene pool remain constant over the generations unless acted upon by agents other than Mendalian segregation and recombination of alleles | ||
| A population that matches the following five main conditions: very large population size, no migration, no net mutations, random mating, and no natural selection | ||
| a drastic reduction in population size | ||
| genetic drift in a new colony | ||
| differential success in reproduction | ||
| genetic exchange due to the migration of fertile individuals or gametes between populations | ||
| change in an organism's DNA | ||
| two or more distinct morphs are each represented in high enough frequencies to be readily noticeable | ||
| measures the average percentage of gene loci that are heterozygous | ||
| comparing the nucleotide sequences of DNA samples from two individuals then pooling the data from many such comparisons of two individuals | ||
| differences in gene pools between populations or subgroups of populations | ||
| a graded change in some trait along a geographic axis | ||
| the ability of natural selection to maintain stable frequencies of two or more phenotypic forms in a population | ||
| Individuals who are heterozygous at a particular locus have greater survivorship and reproductive success than any type of homozygote | ||
| the survivial and reproduction of any one morph declines if that phenotypic form becomes too common in the population | ||
| confer no selective advantage for some individuals over others | ||
| the contribution an individual makes to the gene pool of the next generation relative to the contributions of other individuals | ||
| the contribution of a genotype to the next generation compared to the contributions of alternative genotypes for the same locus | ||
| when members of a population migrate to some new habitat with different environmental conditions | ||
| environmental conditions are varied in a way that favors individuals on both extremes of a phenotypic range over intermediate phenotypes | ||
| acts against extreme phenotypes and favors the more common intermediate variants | ||
| marked differences that are not directly associated with reproduction | ||
| direct competition among individuals of one sex for mates of the opposite sex |
