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.
