Just as man learned to consume everything edible, he also learned to live in any climate. He spread over the whole of the habitable world, being the only animal fully able to do so of its own accord. The other animals that have become accustomed to all climates-domestic animal and vermin-did not become so independently, but only in the wake of man. Page 258.
