To cite few examples of clades: That is, a clade is a group of organisms that consists of a common ancestor and all its lineal descendants. “clade” is simply a fancy word for a taxonomic grouping.
They All Also Descended From A Common Ancestor.
Another example of a clade could be birds: A cladogram is an evolutionary tree. Imagine clipping a single branch off the phylogeny — all of the organisms on that pruned branch make up a clade.
