Document Summary

Same number of digits, all have carpals, a radius, ulna and humerus. A different species would recolonize the area and when another catastrophe struck, they became the next layer of fossils. Naming: swedish naturalist carolus linnaeus was the first modern practitioner of taxonomy, the science that identifies, names and classifies species, developed the system of naming and classifying organisms that is still used today, known as binomial nomenclature. Ex: polar bear = ursus maritimus and the brown bear = ursus arctos. The taxonomic hierarchy: linnaeus created a form of classification that arranges organisms into groups that gradually became smaller and more specific. This type of system is hierarchical: the categories from large to small: domain -> kingdom -> phylum -> Class -> order -> family -> genus -> species -> subspecies: taxon a name designating a group of organisms included within a category of the taxonomic hierarchy.
