I would think most of us would take a pasture full of the Crooked Post type females. If she's not wedge shaped enough, I guess that's the way it goes. Any cow that has a 5 month old calf at foot like that is a good one, regardless of what she looks like. I assume that the cow is "real world", however, what she has gone through still pales in comparison to what the bison cow has survived. I believe that the bison have survived not because of their "wedge shape", but because the ones that could take it lived over the years and those that couldn't take it, didn't. If bison females have to be reverse wedge shaped in comparison to bulls, then she flunks. I just think people are stretching it a bit too far in making the wedge connection. Countless species have survived for eons that look nothing like the bison. Have you ever seen a wedge shaped camel? Wild horses or mountain goats? We visited Custer State Park a couple of years ago and were told by park personnel that they need so supplement the herd with hay sometimes. Is that human intervention? Does that artificially distort the natural selection factor? Are we encouraging the buffalo to become less wedge shaped?
