Wildebeests

More than a million wildebeests, together with hundreds of thousands of zebras, migrate annually between Tanzania and Kenya, following the rains in order to find fresh grass to eat. Zebras eat the tougher, taller grass, leaving the shorter softer grass accessible to the wildebeests. By specializing in different grades of grass, the animals divide the resources, permitting greater species diversity. This division of resources extends to several species of antelopes, helping to maintain the species diversity for which Africa is famous. The capacity to specialize on different grasses appears to reflect the Creator’s intention that diverse species should coexist peacefully.
