Chins are a uniquely human feature.

Why Do Humans Have Chins? They Might Be an Evolutionary Accident, New Research Suggests

The bony facial protrusion might be an evolutionary byproduct that resulted from changes to other parts of the skull, according to a new study

This Hammer Created From an Elephant Bone 480,000 Years Ago May Be the Oldest Known Tool of Its Kind Ever Found in Europe

Discovered in southern England in the mid-1990s, the artifact may have been made by Neanderthals or Homo heidelbergensis, according to a new study

Five quartz arrowheads unearthed in South Africa contained traces of toxins.

Cool Finds

Could These 400,000-Year-Old Rock Fragments Be the Oldest Known Evidence of Human Fire-Making?

Evidence from a site in southeast England suggests early humans were purposefully and repeatedly igniting blazes roughly 350,000 years earlier than previously thought

A new study hints that Australia's first people arrived via a major northern route and a smaller southern route. 

Modern Humans Reached Australia Around 60,000 Years Ago via Two Routes, Genetic Analysis Suggests

The study bolsters one hypothesis of when people arrived at the landmass that became Australia and other islands, and presents some of the earliest evidence of seafaring

For the study, the researchers worked with two adult male macaques that had previously been trained to tap in time with a metronome.

These Monkeys Learned to Tap to the Beat of the Backstreet Boys. Can They Teach Researchers About the Origins of Human Musicality?

Two macaques learned to keep time with various songs, which might point to how humans got their sense of rhythm. But some scientists doubt that the primates’ feat, which required extensive instruction, can give evolutionary clues

The Burtele foot, discovered in 2009

The Human Relative Who Owned This 3.4-Million-Year-Old Foot May Have Belonged to a Species That Lived Alongside Lucy

Newfound fossils in modern-day Ethiopia suggest that the mysterious foot belonged to a recently named species, Australopithecus deyiremeda. The finding could alter the story of human evolution

A new study analyzes the nasal cavity of the “Altamura Man,” a Neanderthal who died between 130,000 and 172,000 years ago

Chimpanzees, like some other apes, kiss each other on the lips. 

How Did Humans End Up Smooching on the Lips? It May Have Started Out With a 21-Million-Year-Old Kiss

Our ancient primate relatives—including Neanderthals—may have enjoyed a nice peck on the lips. But researchers still don’t know why we do it

New research suggests a genetic dynamic that may have contributed to Neanderthals' extinction.

A Single Gene Could Have Contributed to Neanderthals’ Extinction, Study Suggests

New research posits that a genetic incompatibility between female offspring of humans and Neanderthals and their children could have led to pregnancy complications and the eventual end of the species

The first hand and foot fossils clearly linked to Paranthropus boisei reveal the human relative could have handled stone tools.

Discovery of First Fossil Hand Linked to P. Boisei Suggests the Bygone Human Relative Could Have Used Tools

A new study sheds light on the enduring mystery of whether our ancient cousins were toolmakers, too

Yunxian 1 (left) and Yunxian 2 (right) are skulls unearthed in China that had been badly crushed. Scientists digitally reconstructed Yunxian 2 (center) and analyzed its relationship to other early human fossils.

Scientists Reconstruct a Million-Year-Old Skull and Suggest It Could Rewrite Our Timeline of Human Evolution

A recent study dramatically pushes back the date for the emergence of our species, though some researchers call for further evidence
