Narrator in “Unfinished Business”

In the Oligocene, large parts of the world have become highly seasonal. Here in Mongolia, long dry seasons are broken by short, violent wet seasons. The climate has shaped not only the environment, but also the animals. It is survival of the meanest. And they don't come much meaner than this: a giant Enteldont, the bully of the plains. These are distant relatives of the pig. Two metres tall, aggressive and built like tanks, but with a brain no bigger than an orange.
