Lucy, an early human ancestor, could run upright but much slower than modern humans. New simulations show that muscle and ...

whose 3.2-million-year-old remains belonging to Africa's Australopithecus afarensis were long considered to be the species that gave rise to the earliest humans. The updated timeline means the two ...

To get a picture of how Lucy's species, Australopithecus afarensis, moved, scientists compare fossils to the bones of modern humans, as well as to the anatomy of "knuckle-walking" primates like ...

Lucy, an early human ancestor who walked upright on two legs—a milestone in human evolution—had speed and energy efficiency ...

As the University of Boston anthropologist explains, the fossil "Lucy" (Australopithecus afarensis) had a more difficult birth process than A. sediba, in terms of a tighter fit between the foetus ...

Lucy's discovery compelled scientists to rewrite their evolutionary timeline, HISTORY reported ... This species was namedAustralopithecus afarensis after the Afar region of Ethiopia.

Ancient human relatives ran on two legs, like modern humans, but at a much slower pace, suggest 3D computer simulations of Australopithecus afarensis 1 — a small hominin that lived more than ...

This species includes "Lucy," the 3.2 million year old fossil found by Donald Johanson. A. afarensis' small braincases and relatively large teeth and chewing muscles are similar to those of ...

Australopithecus afarensis. “We knew that because it was so complete it was important, but I didn’t realise it would actually launch a new species,” says Johanson. Lucy’s anatomy provided ...

The University of Liverpool has led an international team of scientists to take a fresh look at the running capabilities of Australopithecus afarensis, the early human ancestor famously represented by ...
