Dinosaurs (including birds) are almost certainly a clade, meaning
originally there was one dinosaur species.  This species was so
successful it became a huge, diverse taxon.  The only unfair bit is
judging the clades before their histories are over.

The human (hominine) clade, on the other hand, has only lasted a few
million years.  It has produced a handful of species which are all,
with one exception, extinct.
