In a remote corner of Africa, an extraordinary evolutionary tale is unfolding, uncovered by the actor Jeremy Irons and an award-winning documentary team...It's evolution gone wild[er]!
"There is an unusual pride of lions stalking these swamps," he says. "They are cats that live in water and hunt a single herd of Cape buffalo. Evolution favours predators that can hunt a range of prey. But these lions are defying that trend by becoming specialists. These huge lions are adapting and breeding in isolation on an island in a river that goes nowhere."
[T]he island has become a unique, ecological experiment. In order to exist without the customary spectrum of weaker African prey like zebra, giraffe and impala, the Duba lions have had to develop distinct strategies in order to trap the single available food source.
