Bone discovery suggests a mysterious ancient species of human lived alongside our ancestors

An ancient femur found in a Chinese cave is unlike any bone formerly discovered, suggesting it belonged to a previously unknown human species that lived alongside modern man just 14,000 years ago. The distinctive shape of the bone indicates that the species would have walked differently from humans today, according to the New Scientist.
