.. but we'd be pretty dang foolish not to consider quite a lot beyond that. Your view only works for dumb animals. Insisting on dumb animal behavior for something that is probably Homo something-or-other is pretty darn foolish IMHO. Do we take care of our sick elders or do we feed them and try to protect them? Do we leave them dead on the ground or do we bury them? While they might indeed just be dumb animals, if they are, then we are stupider than we give ourselves credit for because whatever they are, they're consistently outsmarting us. There is no getting around that.
