Document Summary
Pre-lecture: how polyploidy can induce sympatric speciation, definitions of systematics, phylogeny, phylogenetic tree, close relatedness, using examples, systematics. Branch of biology which studies diversity of life and its evolutionary relationships: phylogeny, phylogenetic tree. Evolutionary history of a group or organisms. A branching diagram depicting the evolutionary relationships of groups of organisms formal hypothesis identifying relationships among species. Essential components of the cooperative methods that biologists use to analyze evolutionary processes. Study of phylogenetic relationships based on shared, derived characteristics. Characteristics of organisms that were present in the ancestor of the group that is under study. Do not indicate anything about the relationships of species within a group because they are inherited from the ancestor to all of the members of the group. Characteristics of organisms that have evolved within the group under study. These characteristics were not present in the ancestor. Organisms included within any category of the taxonomic o.
