Document Summary
Microevolution: changes in one gene pool of a population over generations. Macro evaluation: specialization; formation of an entirely new species. Population:all members of one species in one place. 99% of all organisms that lived on earth are extinct. Prokaryotic cells are the oldest fossils and first organisms developed on earth transitional fossils: link older extinct fossils to modern species. Homologous structures: functions may vary, but have the same internal bone structure shows common ancestry. Analogous structure: same function but not the same underlying structure; superficial relations and reflects adaptation to a similar environment. Vestigial structures: evidence that anatomy of animals have evolved; structures that once had a function but no longer do, yet still exist. Closely related organisms go through similar stages in embryonic development. All aerobic organisms contain cells that carry out respiration and require electron transport chains and the polypeptide cytochrome (c)
