Cannot? What about scavenging? Who knows what a deer might come across out
there in the grass? What about the eating of the afterbirth? It's common
in cows, I know, and probably common in other herbivores.
Why does the spine make such a difference to you? Is vertebrate flesh so
very biochemically different from invertebrate flesh? I read your answer
above, but it doesn't make sense to me. If a cow checks for a spine before
it takes a bite of something, OK; but I doubt that happens very often. ;)
