Document Summary
Species are classified together because they share a common ancestor. Systematics: study of organism diversity and evolution relationships. Cladistics/ phylogenetic systematics: approach that separates organisms into different groups based on when they separated. Can be traced to groups most common ancestor. Classification: arrange organisms into groups based on similarities. Homologous traits: traits shared between organismal species. Binomial nomenclature: species have 2 part names. Each taxonomic level gets more specific than the one below. Group = more inclusive and broader range of organisms as one goes up hierarchy. Natural classification: based on aspects of body structure. Phylogenetic classification: place groups of organism that evolved from common ancestor together. More recent separation = more closely orgs are related. Larger taxon = more distant ancestor is. Concern: who is the ancestor and how distant is the ancestor. 23. 2 determine branch in the tree of life. Fungi: fungi (*branched from plantae because they do not partake in photosynthesis)
