One last request: would you take a crack at answering earlier post on
frequency of pre K/T 2ndary flightlessness; and why birds didn't re-evolve
into non-avian dinosaur forms after the K/T. This is another of those
questions which would seem to demand at least feasible hypotheses.
Perhaps you've already ventured into the Tertiary in the archives?
