Clades represent unbroken lines of evolutionary descent. It’s easy to identify a clade using a phylogenetic tree. Just imagine clipping any single branch off the tree. All the lineages on that branch form a clade. kristi anthony

"WebThe common ancestors of birds and mammals were very early (stem) reptiles, which almost certainly possessed three-chambered hearts (two atria, one ventricle). Birds and mammals, however, are alike in having four-chambered hearts (two atria, two ventricles). The four-chambered hearts of birds and mammals are best described as a paraphyletic group " - Counting phylogenetic ancestors
