Theory of EvolutionR
| Question | Answer |
|---|---|
| Evolution | the process of change over time |
| Fossils | preserved remains or traces of ancient organisms |
| Adaptation | any heritable characteristic that increase an organism's ability to survive or reproduce in its enviroment |
| Fitness | describes how well an organism can survive or reeroduce in its enviroment |
| Natural Selection | the process in which organisms with variations most suited to their local enviroment survive and leave more offspring |
| Biogeography | the study of where an organism lives or where it and their ancestors lived |
| Homologous Structures | structures that are shared by a related species and that have been inherited from a common ancestor |
| Analogous Structure | body parts that share a common function, but not structure |
| Vestigial Structure | inherited from ancestors, but have lost most or all of its original function due to different selected pressures on the decendant |
| Comparative Morphology | a branch of science in the structures of living things are compared ti understand the development and relationship among species better |
| Embryology | the study of the early stages of life, before birth |
| DNA Fingerprint | the pattern produced when DNA fragments are seperated by size and shape by gel electrophoresis |
| Species | a group of organisms that share similar characteristics and can interbreed with one another to produce fertile offspring |
| Variation | a difference exhibited by a member of a species |
| Mutation | a change in the genetic material of an organism |
| Gene Flow | change in diversity that occurs when genes from one population are introduced into the gene pool of another population |
| Gene Pool | the combined genetic info of all members in a small population |
| Genetic Drift | a random change in the frequency of alleles in a small population |
| Bottleneck Effect | a form of genetic drift that occurs when there is a sudden and severe decrease in a population size resulting from natural disaster, or habitat reduction |
| Nonrandom Mating | the phenomenon in which some individuals have more opportunity to mate and produce offspring than other individuals |
| Gradualism | the theory that evolution occurs slowly over a long period of time |
| Puntuated Equalibrium | a pattern of evolution in which long stable periods are interrupted by short periods of rapid change |
| Extinction | the death of all individuals in a species |
| Speciation | the evolutionary process in which new species form |
