Just over 50 years ago, paleontologist Donald Johnson unearthed the remains of "Lucy," an ancient human relative who lived ...

New research uses 3D modeling to reconstruct Lucy's running style, revealing surprising insights into the evolution of human ...

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

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 ...

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

About 3.2 million years ago, our ancestor "Lucy" roamed what is now Ethiopia. The discovery of her fossil skeleton 50 years ago transformed our understanding of human evolution. But it turns out her ...

On a lakeside peninsula in Eastern Africa, archaeologists have found clues about a society that lived there over 3 million years ago.

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

Recent research suggests Australopithecus afarensis was able to run upright at speeds of around 5 meters per second ...

Despite being bipedal, Lucy’s running capacity was slow and energetically inefficient compared to modern humans, highlighting evolutionary advancements in human anatomy crucial for endurance ...

in the Afar region of northern Ethiopia that would become a hotspot for ancient human discovery, this understanding took another leap backwards in time with the discovery of Lucy. The part-skeleton of ...
