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

Lucy, a 3.2-million-year-old ancestor of humans, had shorter legs and smaller calf muscles and Achilles tendons. She would ...

That makes it one of the oldest human ancestors found, while also being the most complete example of the link in the human evolutionary chain known as Australopithecus. Portions of the fossilized ...

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.

One day in the summer of 1924, an anthropologist named Raymond Dart made an incredible discovery — and drew a conclusion from ...

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, ...

How about your ancient relatives? Thanks to fossil finds, scientists now know a lot more about our ancient human relative, Australopithecus sediba. The species was first discovered in 2008 in ...

Dart was examining a set of fossils that had been unearthed by miners near the town of Taung in South Africa when he found ...

For Australopithecus sediba, which lived 1.95 million years ago in South Africa, we see "a relatively easy birth process", says study researcher Dr Natalie Laudicina. "The foetal head and shoulder ...

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 ...

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 ...

Australopithecus, Homo erectus, Neanderthal, Homo sapiens. Special Thanks to Dr. Briana Pobiner, Research Scientist and Museum Educator of the Human Origins Program, Department of Anthropology at ...
