| A | B |
| Adaptation | Of evolution, being adapted to a set of environmental conditions |
| Adaptive Radiation | Microevolutionary pattern;a burst of genetic divergences from a lineage that gives rise to many new species each adapted to using a novel resource or a new habitat |
| analogous | body parts that are different in evolutionarily distant lineage but converged int heir structure and function in response to similar environmental pressures |
| biogenisis | the idea that living organisims can come only from other living organisms |
| Common Ancestry | the way things are related to each other(ex:homologous structures) |
| convergent evolution | a pattern of evolution seen when observing analogous structures. Convergent evolution produces species that are similar in appearance+behavior, but son't share common ancestry |
| Darwin | a naturalist of the 19th century, he devised a theory of evolution based on variation+natural selection |
| Divergent evolution | It is the same thing as adaptive radiation |
| Fossil | recognizable, physical evidence of an organizm that lived in the distant past |
| Geographic isolation | the separation of species populations bysignificant geographic barriers such as large bodies of water, mountains, deserts, canyons, or similar features |
| gradualism | evolutionary change is slow, gradual, and continuous, supported by fossil records |
| heterotroph hypothesis | hypothesis that the 1st primative life forms on earth were not able to manufacture their own food |
| homologous | the same body parts that became modified differently, in different lines of descent from a common ancestor |
| industrial melanism | the change to the darker form |
| Lamarck | in the 18th century in france she proposed a theory of evolution including 2 main ideas~use+disuse and transmission of acquired traits |
| Miller | Scientist who tested a particular aspect of the heterotroph hypothesis |
| Organic Evolution | The mechanisms thought to govern the change in libing species over geologic time |
| population | all members of a species that live in a certain area and make up a breeding group |
| punctuated equilibrium | species experience long geologic periods of stability, which is "punctuated" when dramatic changes take place |
| Reproductive isolation | when 2 populations of a species are put in different places, and they adapt differently, theywill not be able to interbreed+produce fertile offspring |
| sedimentary | rocks in which early fossils ar found w/in the layers |
| speciation | process by which new species arise |
| spontaneous generation | The idea that life can arise spontaneously from non-living matter under current conditions on the earth |
| vestigial | structures or organs that seem to serve no useful functions |
