Unusual discovery can lead to reinterpreting the Evolutionary Theory

In the present time, Homo Sapiens is the only existing human species on Earth.

But we all know that things were not always that way. According to evolutionary theory, the first hominids evolved from the apes.

The first human species arose during this evolution and they were later branching into several subspecies.

So, that way appeared Homo Erectus, Homo Habilis and Homo Neanderthaliensis.

Many of these species interbred, giving rise to new individuals.

For example, Neanderthal cohabited with members of Homo Sapiens for a short period of time. The oldest evidence of this crossing is the human jaw fragment found in the Bone Cave from Caras-Severin, Romania, that is approximately 40,000 years old.

New information regarding the crossings of the human species over time was obtained after the discovery of a femur in an archeological site known as the ‘Red Deer Cave’, located in the southwest of China.

Until now, it was believed that all traces of human existence on the territory of Asia disappeared at least 100,000 years ago.

The femur that was discovered belonged to a such an individual and dates back from 14,000 years ago.

From the first observations, it has been observed that the femur belonged to a man who lived in the Upper Pleistocene, that is more than 14,000 years ago.

To find out the origin of the individual, scientists have compared the femur and other bone fragments with the ones of other human species, including Homo Sapiens.

‘Following the observations that we have made, we have found a clear association between the femur we identified and the skeletons of ancient members of the Homo Sapiens. So far, we could not get a lot of information about the newly discovered species’, stated David Begun, a paleoanthropologist at the University of Toronto.
