Ardipithecus ramidus
What distinguishes A. ramidus from other hominid species are its larger upper and lower canines in relation to the post-canine teeth.  Ramidus is generally regarded as the earliest specimen in the hominid ancestry, dating to approximately 4.4 million years.

Ardipithecus ramidus comes to us from East Africa.
