An article in the journal “PLOS ONE” describes a research carried out on a femur found in China, in a cave called Maludong, which means Red Deer Cave. This bone, as well as the remains of the skull, show a mixture of ancient and modern anatomical features. The dating of the femur is approximately 14,000 years old but its appearance is similar to that of Homo habilis, a species thought to be extinct about 1.5 million years ago, and early Homo erectus, appeared about 1.9 million years ago.
