Description:
This site explains how a cladogram is formed and its implications. The cladogram is compared to a family tree, however unlike family trees, ancestors in cladistics ideally give rise to only two descendent species. Also unlike family trees, new species form from splitting of old species. Three possible diagrams showing the relationship between humans, gorillas, baboons, and chimpanzees are demonstrated. The author explains why one diagram is favored and also explains the meaning of nodes and clades.
