I believe this may be true. But then the question becomes more
interesting: why some groups hit and not others? And, why was it just one
body plan that was wiped out forever? And in what way was the biota
structured such that a hit at this time may have had very different
effects than a hit at some earlier time. These questions are more
difficult but more interesting (to biologists anyway).
But the analogy is a poor one. Is the liver Yucatan? In terms of
killing a biota (which it didn't) a more analagous analogy might be some
diffuse killer like ??? which only kills selected cells.
