So Lucy may have lived in a group controlled by one dominant male, who had "a harem, or group of females around it," says Spoor. Try for free Already registered? And might she be our direct ancestor, a missing gap in the human family tree? A work of the American Museum of Natural History uncovered a possible baboon fragment that was found mixed in Lucy's fragments .
In contrast, the only damage we see on Lucy's bones is a single carnivore tooth puncture mark on the top of her left pubic bone. Combined with modifications to the other toes, the bone would have helped Ardi walk bipedally on the ground, though less efficiently than later hominids like Lucy.
Would we have happened at all?
Lucy's Story Institute of Human Origins
Lucy is the common name of AL , several hundred pieces of bone fossils representing 40 percent of the skeleton of a female of the hominin species Australopithecus afarensis.
The Ardipithecus ramidus fossils were discovered in Ethiopia's harsh Afar desert at a site called Aramis in the Middle Awash region, just 46 miles 74 kilometers from where Lucy's species, Australopithecus afarensis, was found in Retrieved October 10, A cast of the original skeleton in its reconstructed form is displayed at the Cleveland Museum of Natural History.
It was immediately obvious that the skeleton was a momentous find, because the sediments at the site were known to be 3. Read More: Lucy the pre-human hominid and fossil hominin, captured much public notice; she became almost a household name at the time. The talus, in her ankle, shows evidence for a convergent big toe, sacrificing manipulative abilities for efficiency in bipedal locomotion.
Ethiopia celebrated the return of Lucy in May In other projects Wikimedia Commons. American Journal of Physical Anthropology. The vertebrae show evidence of the spinal curvatures necessitated by a permanent upright stance. How can this be pushed back millions of years into the past, when soil pressure, carnivore activity, and other natural forces have compromised both the body and the death scene?

Since the discovery of Lucy, paleoanthropologists have found more fossils from Australopithecus afarensis.

At the group's campsite that night, Johanson played a Beatles cassette that he had brought with him, and the song "Lucy in the Sky with Diamonds" came on. While important, however, none of those earlier fossils are nearly as revealing as the newly announced remains, which in addition to Ardi's partial skeleton include bones representing at least 36 other individuals.
Given the patterning of the fractures, Kappelman and colleagues suggest that Lucy fell out of a tree, hitting the ground feet-first and then attempted to break her fall with her arms. A later reconstruction by Tim White showed a broad iliac flare and a definite anterior wrap , indicating that Lucy had an unusually broad inner acetabular distance and unusually long superior pubic rami.
After making the discovery, paleoanthropologist Donald Johanson headed back to his campsite with his team. There was controversy in advance of the tour over concerns about the fragility of the specimens, with various experts including paleoanthropologist Owen Lovejoy and anthropologist and conservationist Richard Leakey publicly stating their opposition.
