Elephants
There are about 500,000 African elephants in the wild. Poachers hunt elephants for their tusks, a relationship that has changed their evolutionary path -- elephants with shorter tusks are breeding more and producing offspring with increasingly stunted tusks. Elephants don't breed until they're teenagers and gestation lasts for 22 months -- creating a population unable to bounce back.
