Careers will be even shorter if scientists summarily dismiss honest
questions fueled by new research. Again, it is not written that mammals
or birds did not affect speciatio of non-avian dinosaurs. No matter how
much you would like to dismiss it.
New evidence suggest mammals were more diverse than previously believed at
the K/T. Shouldn't this even cause a ripple of a question in a scientist
mind? Is there something about mammals and birds around the K/T which a
priori eliminates them from consideration?
Can anyone here pretend to know what feats mammals and birds of the K/T
could or could not do? If not, then don't be so dismissive!
