D models of Australopithecus afarensis suggest the muscular adaptations that made modern humans better runners.

It proved to be the first of 47 bones of a single individual – an early human ancestor whom Johanson nicknamed "Lucy." Her discovery would overturn what scientists thought they knew about the ...

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

Lucy, our 3.2 million-year-old ancestor of the species Australopithecus afarensis, may not have won gold in the Olympics – ...

Body size is estimated from weight-bearing bones, including those in the hips. In Lucy's species, Australopithecus afarensis, the average adult male weighed near 110 pounds and stood around 4 feet ...

The bones that make up Ardi's feet suggest that humans and chimpanzees evolved separately. Lucy is also a female human-like fossilised skeleton, and dates from 3.2 million years ago. Lucy's bones ...

This led to the bones being fossilized. Those remains, now known to the world as 'Lucy', were discovered fifty years ago, becoming one of the most significant fossil discoveries of all time.

More fossils were unearthed; a complete lower jaw, parts of a ribcage, pelvis and shin bones, ultimately resulting in a 40 per cent complete skeleton. Johanson’s find became known as Lucy ...
