TED-Ed: Why animals help each other | Ashley Ward

The video explores the concept of cooperation and altruism in the animal kingdom, challenging the traditional view of 'survival of the fittest' as purely about physical strength. It highlights examples like humpback whales rescuing seals, mutualism and parasitism among cleaner fish, meerkat sentry behavior, and reciprocal altruism in vampire bats. The video suggests that fitness can also involve cooperation and altruism, with animals sometimes acting selflessly to protect others, even unrelated species.
