This article is about the discovery of an Australopithecus sediba fossil that was found in South Africa last year. Researchers say that this could be our oldest direct ancestor dating back 1.98 million years. Newly exposed cave sediments in the Malapa Cave where the fossils were found helped to determine how old the Australopithecus sediba were. This discovery is important to the study of evolution because we are still making progress on our ancestors. Just this last year, we found the oldest direct human ancestor, which helps to piece together how we evolved better.
