A clade is a group of organisms that includes an ancestor and all of its descendants. In this case, species 2-5 share a common ancestor and all belong to the same monophyletic group, which is consistent with a clade. A paraphyletic group would include an ancestor and some, but not all, of its descendants. A polyphyletic group would include organisms with different ancestors but similar characteristics. A cladogram is a diagram that represents the evolutionary relationships among different groups of organisms. An evolutionary tree is a synonym for a phylogenetic tree, which is a branching diagram that shows the evolutionary history of a group of organisms.
