The oldest known fossil skeleton of a human ancestor--a female Ardipithecus ramidus specimen nicknamed "Ardi" (pictured)--has been found, scientists revealed yesterday.
The find reveals that our ancestors underwent a previously unknown stage of evolution more than a million years before Lucy, the early human ancestor specimen that walked the Earth 3.2 million years ago. Ardi lived 4.4 million years ago, according to researchers.
