Scientists report the finding of a 2.8-million-year-old jawbone (the "Ledi jaw") forming a potential link between the 3.2-million-year-old hominin (human-like primate) Lucy (Australopithecus) found in the same area, and the 2.35-million-year-old remains of "Homo habilis" found at nearby Hadar. If assigned to the genus "Homo", the new remains represent the oldest known human, some 400,000 years older than previously found.
