Pack animals hunt and exist on instinct and fear. In fact fear is their entire motivating factor. Even within the pack, survival is the ruler. a wolf certainly does keep a kill for itself, especially males. The female is first to eat her kill the cubs fight for the leftover and establish a pecking order.
As for all that "human selection" stuff, blah blah blah. Humans didn't "evolve" they were created with rational, thinking minds, something animals do not possess. We posses all the same faculties we were created with. Our adaptability is all information stored in our genes that becomes active as our environment warrants. Move to the mountains, each generation will develop bigger lungs. If they move back to sea level, they reduce. Always has been that way.
They aren't? If humans aren't animals, what are they? Plants? Fungi?
We share the same DNA building blocks. The only way to say we're not animals is by selective definition. A human that grows up feral in the wild behaves exactly like a wild animal. They can later learn some key words but are retarded and incapable of learning speech in adulthood. They are animals. Have you known any dogs? They learn and socialize like us, skills originally selected for by pack hunting, like us.
