Scientists say that DNA taken from an ancient finger bone found in a Siberian cave near the Altai region may belong to a previously unknown type of pre-human. The scientists say the extinct "hominin" (human-like creature) lived in Central Asia between 48,000 and 30,000 years ago. The bones were found with a bracelet, and they've called this ancient skeleton X-woman. One of the scientists Professor Colin Groves said that they think she might be a new species that we didn't know existed until now.

It changes our understanding in that we now know there was something different living in the Altai and perhaps elsewhere at the same time as there were Neanderthals in Europe and homosapiens in Africa and just emerging from Africa. But we don't know unfortunately what species this new thing was.
