(click for larger image in new window) A branching treelike diagram used to illustrate evolutionary (phylogenetic) relationships among organisms. Each node, or point of divergence, has two branching lines of descendance, indicating evolutionary divergence from a common ancestor. The endpoints of the tree represent individual species, and any node together with its descendant branches and subbranches constitutes a clade. |
