The Missing Link - New Findings
The discovery of "Ardi" in 1994 in Ethiopia may well have been the missing link scientists had been searching for. This week scientists revealed the result of this 15 year long study.
The partial skeleton of a female Ardipithecus ramidus, nicknamed "Ardi", is estimated to be about 4.4 million years old.
This changes the theory that prevailed until now - i.e. humans must have been walking on all fours. Since apes also descend from Ardi but they knuckle-walk, this also means that knuckle-walking is an adaptation and that therefore apes evolved as much as humans did.

The partial skeleton of a female Ardipithecus ramidus, nicknamed "Ardi", is estimated to be about 4.4 million years old.
This hominid seems to have been the ancestor to both humans and apes. However, evidence shows that she did not knuckle-walk but walked standing upright. This means that our ancestors walked straight over one million years ealier than previously thought.
