Document Summary
Changes in populations/species/groups & changes in allele-trait frequencies in populations over time. Changes in allele frequencies that occur over time within population. Patterns of changes in groups of related species over broad periods of geologic time. *patterns determine phylogeny=evolutionary relationships among species & groups of species. Body parts can develop w/ increased usage *unused parts weakened. Body features acquired during lifetime = passed down to offspring. Wrong= only changes in genetic material of cells can be passed to offspring. Organisms produced offspring with changes = transform each later generation. Slightly more complex - no extinction/splits into more species * wrong. Survival of fittest -darwinism now neo-darwinism synthetic theory of evolution. Fossils reveal prehistoric existence of extinct species = often found in sediment layers. *deepest fossils represent oldest specimens & large/rapid changes produce new species. 2- biogeography - geography to describe distribution of species. *unrelated species in different regions of world look alike when found in similar environment.
