Lucy redux: A review of research on Australopithecus afarensis
inin species Australopithecus afarensis was recognized as the oldest most apelike human ancestor Although speci-mens now attributed to the species had resided in fossil collections since the 1930s the bulk of the sample was amassed during field work in the 1970s at two sites Hadar Ethiopia and Laetoli Tanzania Today the species’ |

How did Au afarensis resemble a chimpanzee?
Au. afarensis possessed both ape-like and human-like characteristics. The top of its skull (the cranial vault) was slightly domed and its brain was comparable in size to a chimpanzee's. Its face projected outwards, less so in females than in males. Some Au. afarensis skull specimens show evidence this species possessed powerful chewing muscles.
Is aus tralopithecus afarensis a bipedal species?
Subsequent study of this collection and the sample from Laetoli, Tanzania, led to the recognition of the craniodentally primitive, bipedal species Aus tralopithecus afarensis5• Morphological and metric variation in the A. afarensis hypodigm were initially explained as intra specific, partly because of sexual dimorphism6.
What are the characteristics of Au afarensis?
Au. afarensis had both ape and human characteristics: members of this species had apelike face proportions (a flat nose, a strongly projecting lower jaw) and braincase (with a small brain, usually less than 500 cubic centimeters -- about 1/3 the size of a modern human brain), and long, strong arms with curved fingers adapted for climbing trees.
What is Australopithecus afarensis?
This article includes information from Our Human Story by Dr Louise Humphrey and Prof Chris Stringer. Australopithecus afarensis is one of the best-known early hominins thanks to an extraordinary skeleton known as Lucy. Find out what we've learned about this species and important fossils.
