Document Summary
Does biology get more complex: single celled organism evolves to mulicellular. Upward and downward causaion: genes -> organism, higher-level controls of gene expression, genes were thought to be a blueprint of an organism but now we know there is signalling that goes both upward and downward. Meteor hit and volcanic erupion caused mass exincion. Dinosaurs might have been able to keep mammals down. We are primates: is a large difereniaion. A phylogeneic tree or a phylogeny illustrates the evoluionary history and relaionships between some groups of species: a phylogeny is essenially a theory embodied in a diagram. Because it can vary depending on what you look at to create it. Humans in relaion with other primates: most recent with chimps. Using a convenion from linnaeus (18th century) animal species are ideniied by two italicized words: ex. Phylogeny: the genealogical history of a group of organisms represented by its hypothesized ancestor-decendent relaions.
