Document Summary
Process of speciation is a gradual one gives rise to the species we see today. Species are related to each other in a tree of life . Anatomical characteristics can help decipher who is more closely related to whom. Inherited from common ancestor of all primates. Only things new in evolution that are indicative of link. Only synapomorphies are informative for reconstructing evolutionary relationships. Only some types of traits are useful in figuring out what this branching type of tree looks like. Human variation all homo sapiens but holds great diversity. Species no gene flow between two species. Group of local population sharing part of the geographic range of a species but are different from one another (other subspecies) based on one or more phenotypic traits. There is some gene flow between populations. Smaller groups within species, temporally and geographically restricted, within. Hardy weinberg equilibrium which the majority if mating(s) occur.
