In 2008, Professor Lee Berger--with the help of his curious 9-year-old son--discovered two remarkably well preserved, two-million-year-old fossils of an adult female and young male, known as Australopithecus sediba; a previously unknown species of ape-like creatures that may have been a direct ancestor of modern humans. This discovery of has been hailed as one of the most important archaeological discoveries in history. The fossils reveal what may be one of humankind's oldest ancestors.
