Human Origins

Chimpanzees, bonobos and gorillas tend to walk on their knuckles, while macaques and capuchins walk with flat palms.  

Did Human Ancestors Walk on Their Knuckles Like Today’s Chimpanzees? New Research Adds More Evidence to the Debate

After investigating thousands of wrist bones, scientists suspect the last common ancestor species of humans and chimpanzees may have navigated the world on its knuckles

Around 90 percent of people are right-handed.

Why Is Nearly Every Person Right-Handed—but Not Every Ape and Monkey? New Research Explores the Evolutionary Origins of Human Handedness

Brain size and bipedalism are the most likely drivers of our species’ right-hand dominance, according to new research

Archaeologists think the green minerals found in the cave might be malachite, which is treated and processed to make copper.

Mysterious Green Rocks Discovered in a Remote Cave in Spain Might Be Signs of Prehistoric People Working With Copper

The find challenges assumptions that people in the region thousands of years ago did not spend much time at high altitudes

New research indicates that Neanderthals had the genetic hardware for language.

Did Neanderthals Have Language? New Research Suggests They Had the Genetic Hardware for It, Like Humans

Specific genomic regions that seem to play a role in human language development evolved hundreds of thousands of years ago, before humans and Neanderthals diverged from a common ancestor, a new study finds

Chimpanzees from the Western group attacking members of the Central group in 2019.

These Wild Chimps Have Been Fighting in a ‘Civil War’ for Nearly a Decade. It’s the Bloodiest Split Ever Seen Among Their Kind

The Ngogo chimpanzees in Uganda have divided themselves into two main factions, and dozens of deaths have been recorded since the split in 2018. A new study details the unprecedented violence, which could shed light on the evolutionary underpinnings of human warfare

After Nearly 80 Years of Doubt, Scientists Say a Spear Lodged Between Elephant Ribs Offers Evidence That Neanderthals Hunted Big Game

In 1948, amateur archaeologists unearthed the remains, which should have shifted researchers’ views of Neanderthals. But poor documentation sowed skepticism in the scientific community

Cool Finds

These 17-Million-Year-Old Fossils Could Rewrite the Evolutionary Tree of Apes—Including Humans

Jawbone fragments and teeth from a previously unknown species hint that the evolution of modern apes occurred in what’s now North Africa or the Arabian Peninsula, rather than in East Africa

Little Foot's skull was distorted and damaged, so researchers spent years digitally reassembling the bones to understand what the individual's face might have looked like 3.67 million years ago.

New Research

See How Scientists Reconstructed the Face of Little Foot, a Human Ancestor Who Lived 3.67 Million Years Ago

For the first time, researchers have digitally reconstructed the facial fragments of the individual, who belonged to the Australopithecus genus

Researchers investigated 112 decorated ostrich eggshell fragments discovered at three sites—two in South Africa and one in Namibia.

New Research

These Intricately Decorated Ostrich Eggshells Suggest Our Ancestors May Have Understood Basic Geometry 60,000 Years Ago

The lines, right angles and other mysterious designs required careful planning and robust cognitive abilities, according to a new study

Researchers dubbed one experiment involving a roughly one-foot-tall crystal "The Monolith" in honor of Stanley Kubrick's iconic film 2001: A Space Odyssey.

Chimps Seem to Love Crystals. Their Attraction Might Help Explain Humans’ Obsession With the Shimmering Stones

Hominins have been collecting calcite and quartz for at least 780,000 years. A new study hints at why

Neanderthal Men May Have Often Hooked Up With Human Women Thousands of Years Ago

Most people alive today carry a little Neanderthal DNA—except in a few spots. A new study might explain why

Researchers collected chimp urine from leaves and puddles on the forest floor in Uganda.

Wild Chimpanzees Love to Eat Boozy Fruit. Scientists Say the Proof Is in Their Pee

The work further hints that humans may have inherited our penchant for alcohol from our ape ancestors

The team analyzed 260 engraved objects discovered in caves in what is now southwest Germany, including this 40,000-year-old mammoth figurine.

New Research

Humans May Have Used These Mysterious Symbols to Encode Information Tens of Thousands of Years Before the First Writing Systems

The symbols, discovered on 40,000-year-old artifacts in caves in southwest Germany, may have been a precursor to the first written language

The study focused on Kanzi, a language-trained bonobo who died in March 2025 at the age of 44.

Can Apes Play Pretend? What Scientists Learned From Having Imaginary ‘Tea Parties’ With Kanzi the Bonobo

A new study provides evidence for imagination in a captive-raised, English language-trained animal

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 wooden tool, which was likely used to dig through mud, was found near elephant bones.

Cool Finds

Archaeologists Unearthed a 430,000-Year-Old Stick. After Careful Analysis, They Say It Could Be the Oldest Wooden Tool Ever Discovered

Found in southern Greece, the stick was one of two wooden artifacts that appear to have been shaped intentionally, according to a new study

Researchers used an electron microscope to take a closer look at the bone fragment.

New Research

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

Archaeologists Just Discovered the Oldest Known Evidence of Poison Arrows, Which Hunters Used to Slow Down Their Prey 60,000 Years Ago

New research reveals traces of plant toxins on arrow tips in South Africa, suggesting that the technique was used tens of thousands of years earlier than scientists thought

New Fossil Analysis Suggests This Seven-Million-Year-Old Primate Walked on Two Legs, Potentially Making It the Oldest Known Human Ancestor

Fresh findings about arm and leg bones advance the debate over whether Sahelanthropus tchadensis was bipedal, but not everyone is convinced
