afarensis is one of the better known australopithecines, merely with regard to the number of samples attributed to the species.
The afarensis material is important in that it is the best known early hominid species (although as earlier anamensis and/or ramidus material becomes better known, it will lose much of its focus as the earliest known hominid material for which much is known).

Australopithicus afarensis is a recently discovered Hominid species which lived in north east Africa, in the Hadar region of Ethiopia).
afarensis is classified as an ape, not a human.
There is evidence that, contrary to previous assumptions, these early Hominids had developed bi-pedalism prior to the disappearance of woodlands and forests in eastern Africa--that is, our Hominid ancestors were by chance "pre-adapted" to the conditions of drier, more open country that came to prevail in eastern Africa later on.

Forgetting that rather simplistic image for a moment, the upshot of all this is that relatively intelligent, upright, tool-using ancestors of modern man lived in eastern Africa as early as 2.5 million or 3.6 million years ago, or almost twice the time span of previous estimates.
Whether australopithecus afarensis itself was our direct ancestor is, however, an entirely different matter, although the discovery of a male A.
Australopithecus anamensis (anam is the Turkana word for lake) is thus the earliest bipedal hominid yet found, and the discovery has only started to fuel more controversy about whether australopithecus could indeed have been our direct ancestor.

The gracile australopithecines (members of the genus Australopithecus) (Latin australis "of the south", Greek pithekos "ape") are a group of extinct hominids that are closely related to humans.
The fossil record seems to indicate that Australopithecus is the common ancestor of the distinct group of hominines, now called Paranthropus (the "robust australopithecines"), and most likely the genus Homo which includes modern humans.
