Golden lion tamarins have evolved a clever way to keep their population size steady in the face of predation. They almost always give birth to twins.
Our quest to track primates' astonishing rise to power leads us to the Americas, the final continents to be colonized by man's closest relatives. Join us as we reveal the incredible journey a group of monkeys took to get here from Africa 35 million years ago. We then come face-to-face with some of the new branch of primates, who adapted to this environment in weird and wonderful ways, including spider monkeys, capuchins, and the king of the primates: humans.
