Human Origins

Humans are unique creatures on the planet, though it wasn't always this way. Long ago, some bizarre human relatives, such as Nutcracker Man and a Homo species whose miniature bodies resembled the hobbits on Lord of the Rings, roamed Earth. Scientists are even finding evidence that modern humans crossed paths with some of our relatives, with fossils suggesting Homo sapiens may have had sex with Neanderthals and even a newly discovered species called the Denisovans.
