cladogram science definition
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.
evolutionary relationship among primates, showing that chimpanzees and bonobos are more closely related to each other than to humans, and that all three are more closely related to each other than they are to gorillas, orangutans, and baboons
