Summary.
During a safari in Kenya, I watched a pride of lions stalk a herd of zebra in silence for nearly 90 minutes. At that point, a lion cub rose up from his crouched position, and the zebra scattered. The female lions growled at the playful cub and moved on, well aware that their pride’s survival was wholly dependent on their fitness — their ability to adapt to their environment and gain advantage in the form of food.
