If there is any way at all to say "higher" or "lower" in evolution, it is
precisely that: as defined by time. He was certainly *more* correct than most
who'd use these terms, even if he was not really correct.
But that of course means that today's huzmans are as "high up" as every single
bacterium in their lower intestines. And in the scope of the original question:
each and every dino (avian or not) at the time of the Big Impact was just as
"high up" as any other at that time - because they all had progressed *the
same* distance in time from the original dino ancestor.
