In October 2004, the understanding of the human family tree was turned upside down. Anthropologists reported that they had discovered the bones of a tiny, unknown hominin, on the Indonesian island of Flores. It was named Homo floresiensis, but it's often called "the hobbit" for its short stature and oddly proportioned feet. It’s been at the center of a major controversy in the field ever since. Part of the "Eons" series.
