Scientists have just uncovered the skeleton of a young boy who died in a cave two million years ago. Named Australopithecus sediba, the two-million-year old boy is believed to be what could reveal the secrets of the origin of humanity.

Unearthed in South Africa, the 130-cm specimen had the ability to walk on its two legs and swing in trees using its strong curved arms, according to scientists. The boy was found together with an adult that was believed to be his mother. These specimens have been hailed by scientists as a most extraordinary find that could contribute greatly to evolutionary science.

The juvenile male is believed to have died in a deep cave, along with another human being considered as his mother, a horse, a wild dog, a saber-toothed cat, a hyena and several other animals.

It is also believed that the boy was nine years old when he died and seemed like he was looking for water in the cave. His skeleton was found by a young boy roughly his age.

There are substances on his teeth, which are thought to be plaque. Scientists are also looking into what may be prehistoric tools.

Australopithecus sediba is considered as a possible “missing link” that could connect the evolution of apes to humans, although the more technical term scientists use is “transitional species.”
