Does anyone else hate his "historical context" thing?
| Question | Answer |
|---|---|
| Macroevolution | All life today descended from prokaryote cell (3.8 bya) |
| Microevolution | Speciation from ancestral stock due to isolation (e.g. Darwin's Finches) |
| Charles Darwin (1859) | Proposed descent w/ modification through Natural selection by environment |
| Georges Buffon (1750) | Early French evolutionist; believed that life evolved in old earth |
| Adaption | Inherited characteristics that improve ability to survive and reproduce |
| Galapagos Islands | Chain of volcanic islands; showed Adaptive Radiation (finch, tortoise) |
| Charles Lyell (1820) | English geologist; suppported Uniformitarianism (slow geology process) |
| Thomas Malthus (1818) | Human population population>environmental carrying capacity |
| Descent with Modification | Descendants of ancestral organisms spread to diverse habitats=> Adaptive |
| Natural Selection | Ind. w/ inherited characteristics. Well adapted to environment leave more offspring |
| Fossils | Perserved remains or markings left by organism that lived in past |
| Fossil Record | Chronological collection of life's remains in perserved in rock layers |
| Extinct | Organisms that no longer live today |
| Geographic Distribution | Organisms geographical near share more similarites |
| Homologous Structures | Similar structure in species sharing a common ancester |
| Mammalian Forelimbs | Most commonly used example of Homologous Structures |
| Vestigal Structures | Remnant of structure once used in ancester; no clear function today |
| Ontogeny/Phylogeny | Embryonic development supposedly repeats stages of evolutionary pa-(word got cut off) |
| Molecular Biology | High frequency of shared DNA/protien sequencein related species |
| Population | Individuals of same species living in same area w/ shared gene pool |
| Finches | 13 species on Galapagos Islands=> adaptive rad. from common ancestor |
| Biotic Potential | Reproductive ability of most species>environmentl carrying capacity |
| Carrying Capacity | # of organisms in population that an environment maintains |
| Biological Species | Groups of population whose members all inbreed=> shuffle alleles in gene pool=>variation |
| Artificial Selection | Selective breeding of domesticated plants/animals => offspring w/ desired traits |
| Gene Pool | All alleles of individuals that make up a given population |
| Sexual recombination | Meiosis & Fertilization => shuffle alleles in gene pool => variation |
| Hardy Weinberg Equilibrium | Frequancy of alleles in gene pool (large population) remains constant over time |
| Genetic Drift | Change in gene pool if population due to chance (greater in small population) |
| Bottleneck Effect | Natural disasters decide population size=> decide genetic variables=> reduce adaption differences |
| Founder Effect | A few individuals colonize new habitats => increase genetic drift in new |
| Gene Flow | Exchange of genes between populations=> decide genetic differences |
