WebRooted phylogenetic trees: The root of a phylogenetic tree indicates that an ancestral lineage gave rise to all organisms on the tree. A branch point indicates where lineages diverged from each other. A lineage that evolved early and remains unbranched is a basal taxon. When two lineages stem from the same branch point, they are sister taxa. WebTaxonomy involves the identification and classification of species. 2. Explain how species are named.
