Document Summary
Study of the diversity of life and evolutionary relationships. Involves identification, description, classification, and naming of organisms based on: Knowing an organism"s identity & evolutionary treatment and venomous animals conservation biomedical research models. Superficial similarities are insufficient to determine evolutionary relationships. lineage can be crucial. Arrangement of organisms on their hierarchical groups based on their similarities and differences or evolutionary relationships. Older forms of traits, present in ancestors of a taxon, recognizable in descendants. You see which species are closer to each other. Why you might see a combination of ancestral and derived characters. Natural selection will favor changes in some habitat. Can be determined from fossils, embryos, and outgroup comparison. Compare group under study of more closely related species. Genes (rather than loss and gains of alleles underlying the trait itself. Ex: dentate marsupial frog(only known from w/ mandibular teeth true teeth in lower jaw) Tracking back into time that how long ago it was that two lineages split.
