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 ...

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.

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

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 running.
