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

The University of Liverpool has led an international team of scientists to take a fresh look at the running capabilities of ...

By digitally modeling muscles and tendons for the skeleton of Lucy (Australopithecus afarensis), researchers determined that our hominin ancestors could run well but topped out around 11 mph.

Lucy's species walked upright but lacked modern running abilities, revealing key evolutionary adaptations in humans.

It’s the first known partial skeleton representing one of our early relatives, Australopithecus afarensis. Between 3.9 million and 2.9 million years ago, these early humans lived among the ...

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 ...

In a study published in Current Biology, researchers have revealed that Australopithecus afarensis, an ancient hominin species, exhibited a limited capacity for running. This small bipedal ancestor, ...

It had been thought that A. anamensis was the direct ancestor of a later, more advanced species called Australopithecus afarensis, which in turn has been considered a direct ancestor of the first ...

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 ...

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 ...

In an interesting and intriguing recent finding, research shows that Lucy's species - Australopithecus Afarensis, was not the only early human species roaming the Earth at the time ...

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 ...
