Recent fossil finds could mean that "Lucy" wasn't our direct ancestor, some scientists say. Others strongly disagree.

Revolutionary fossil evidence from Ethiopia is challenging decades of scientific consensus about human origins. New discoveries suggest that the famous Lucy fossil, long considered a direct ancestor ...

A foot fossil found in Ethiopia belonged to an ancient human. The finding could knock one of the most famous names in human evolution from her spot on the family tree.

Lucy's position in the history of human evolution is currently being challenged. The Lucy fossil species, or Australopithecus afarensis, was long believed to be an ancestor species that humans ...

Natural history is a difficult thing to conceptualize. You’ve got eons of undocumented progress, like the evolution of many species. Take, for example, the Australopithecus, an ancient great ape ...

The latest fossil un-earthed from a human ancestral hot spot in Africa allows scientists to link together the most complete chain of human evolution so far. The 4.2 million-year-old fossil discovered ...

When studying how fossil hominids moved, researchers usually analyze the morphology of bones—which is crucial for understanding the evolution of bipedalism—focusing mainly on muscle insertion sites.

Scientific evidence from the last decade continues to correct the classical model of human origin. Australopithecus Afarensis, the species to which the legendary Lucy belonged, discovered in 1974, was ...
