The two major surviving clades of diapsids include modern animals like snakes, lizards, crocodiles, and birds

A clade is a branch in a cladogram that has a single common ancestor with all of its offspring. An evolutionary tree that depicts the relationships between species' ancestors is called a cladogram. In the past, cladograms were created using similarities among species' phenotypic or physical characteristics.

All hominoids, including humans, chimpanzees, gorillas, orangutans, and gibbons, are members of this group. The Hominoid clade is a subgroup of the Anthropoids, a broader clade that includes Old World and New World monkeys. The use of a phylogenetic tree makes clade identification simple. Just visualize pruning even one branch from the tree.
