African elephants have long been thought of as a single species, but a critical mass of genetic studies now proves there are two.

Without elephants, Africa's landscape would be unrecognizable, yet these animals have fallen by the hundreds of thousands as a result of two enormous waves of poaching in this century - one in the 1970s and 1980s, the other, beginning around 2009, now underway.

For almost two centuries, American gray wolves, vilified in fact as well as fiction, were the victims of vicious government extermination programs. By the time the Endangered Species Act was passed in 1973, only a few hundred of these once-great predators were left in the lower 48 states.
