Document Summary
Describe the difference between shared primitive and shared derived traits o o. Explain why a classification of system containing class reptilia and class aves is not valid. Identify cladogenic and/or anagenetic events oh a phylogenetic tree. Explain why shared, derived characters indicate close evolutionary relationship o. Explain how a phylogenetic tree can indicate the timing of species diversification. Define what is meant by parsimony and know how the principle of parsimony is used in phylogenetic reconstruction. Science of describing, naming, and classifying living and extinct organisms and viruses. Study of biological diversity and the evolutionary relationships among organisms, both extinct and modern. Taxonomic groups are now based on hypotheses regarding evolutionary relationships derived from systematics. Phylogeny - evolutionary history of a species or group of species. To propose a phylogeny, biologists use the tools of systematics. Trees are usually based on morphological or genetic data. A hypothesis of evolutionary relationships among various species.
