An ancient human-like creature that may be a direct ancestor to our species has been described by researchers. The assessment of the 4.4-million-year-old animal called Ardipithecus ramidus is reported in the journal Science.
Even if it is not on the direct line to us, it offers new insights into how we evolved from the common ancestor we share with chimps, the team says. Fossils of A. ramidus were first found in Ethiopia in 1992, but it has taken 17 years to assess their significance.
