I don't see why or how you would consider the "phenetic" difference between a sparrow and an ostrich to be greater than that between _Tyrannosaurus_ and _Diplodocus_. Yet, under Linnaean (and Kinman-ian) taxonomy, there are a multitude of bird "orders", yet the array of theropods and sauropods all get funneled into a single order, the Saurischia (or Saurischiformes).

It sure doesn't make any sense to me.
