Lower-ranking wolves enjoy none of these benefits--staying close to home, breeding rarely and usually dying before they’re four.
Humans often report the same kind of temperamental determinism. Families are full of stories of the inexhaustible infant who grew up to be an entrepreneur, the phlegmatic child who never really showed
