others have begun seeking the roots of ambition in family, culture, gender,
genes and more. They have by no means thrown the curtain all the way back, but
they have begun to part it. If humans are an ambitious species, it’s clear we’re not the only one. Many animals are known to signal their ambitious tendencies almost from birth. Even before wolf pups are weaned, they begin sorting themselves out into alphas and all the others. The alphas are quicker, more curious, greedier for space, milk, Mom--and they stay that way for life. Alpha wolves wander widely, breed annually and may live to a geriatric 10 or 11 years old.
