Human Origins

The brain is a glutton for glucose, broken down from carbohydrates, which often come from starchy or naturally sweet foods. 

Meat Wasn’t the Only Food That Drove Early Humans to Evolve Bigger Brains. Sugar May Have Fueled the Organ’s Enlargement, Too

Scientists examined four million years of hominin diets. They found that natural sugars may have supplied energy—in the form of glucose—to growing brains before cooking made starchy foods easier to digest

The belly is one of the most ticklish body parts across analyzed cultures.

From Armpits to Feet, Our Ticklish Hot Spots Are Surprisingly Universal. The Finding Offers Clues About the Sensation’s Evolutionary Origins

A new study probes the basics of gargalesis, a poorly understood type of tickling caused by firm, repetitive touches that typically elicits laughter and squirming

A new study, which has not been peer reviewed, suggests Denisovans might have towered over their ancient hominin peers.

Thousands of Years Ago, Denisovans Might Have Been Huge, Especially Compared to Their Archaic Human Neighbors

New research offers rare insight into our extinct cousins who lived in Asia and who may have towered over petite “Homo erectus”

Some modern humans might be taller and more muscular because of a Neanderthal-derived gene variant that affects the growth hormone pathway.

Got a Brawny Build? You Might Be Able to Thank Your Neanderthal Ancestors, According to a New Study

New research hints that some living people inherited a gene variant from Neanderthals that has made them slightly taller and more muscular than their peers

Previous research hinted at ghost ancestry in our DNA, but the new work helps pinpoint the timeline of when the ancient relatives' genetic material entered our genomes.

Traces of Two Extinct ‘Ghost’ Ancestors Were Found Hiding in Modern Human DNA, Hinting at Our Extremely Complex Family Tree

Researchers used a new method to investigate past interbreeding with Homo sapiens that doesn’t require ancient DNA. The technique identified areas of living humans’ genomes that came from unknown hominins, including one from a 1.8-million-year-old lineage

Each bird figurine measures less than an inch long.

Cool Finds

Archaeologists Discover Two Thumbnail-Size Bird Sculptures Carved From Mammoth Ivory 40,000 Years Ago

Measuring less than an inch long, the figurines were buried beneath Germany’s Hohle Fels Cave, where some of the world’s oldest known figurative artworks have been found

An overview of the excavated track surface with a mix of deeper hippopotamus and antelope footprints and shallower hominin tracks visible

Ancient Fossil Footsteps Found in Kenya May Hint That an Early Human Relative Was Larger Than Previously Thought

The trackway sheds light on how some hominins moved around their environments and with one another

Male chimpanzees were more likely to exchange friendly touches with other males—like Little Jake and Little Joey shown here.

Chimpanzees and Bonobos Use Hugs, Kisses and Friendly Pats to Keep the Peace, Just Like Humans, a New Study Suggests

Since all three ape species diverged from a common ancestor that lived roughly six million to eight million years ago, the findings hint that friendly touching to diffuse tension has deep evolutionary origins

Researchers discovered that Neanderthals and Homo sapiens appeared to collect the same type of snail shell, possibly for ornamental or symbolic purposes.

Our Ancestors Loved Shell Trinkets, Just Like Neanderthals. New Research Suggests It’s a Sign of Shared Culture Across Species

Based on artifacts found in a limestone cave on the Mediterranean coast, scientists think the two species might have shared similar survival strategies, stone tool technologies and symbolic traditions

Homo floresiensis (center) had a skull about the size of a grapefruit and stood a little more than three feet tall.

How a Hungry Komodo Dragon Led Scientists to Determine Our Small, Hobbit-Like Cousins Probably Weren’t That Smart After All

New research indicates “Homo floresiensis” probably wasn’t hunting big game or using fire on Flores Island, suggesting the small-brained species wasn’t quite as “behaviorally advanced” as once hypothesized

Some of the Neanderthal remains that were analyzed in the new study

Why Did Neanderthals Go Extinct? Inbreeding Probably Wasn’t to Blame for Their Demise in Northwestern Europe, a Study Suggests

In contrast to those who resided in Siberia, Neanderthals who lived in what’s now Belgium and France shortly before the species vanished seem to have been genetically diverse and healthy

Scientists collected samples from 11 caves in Spain and Portugal.

In a Scientific First, Researchers Recovered Ancient DNA That Humans Left Behind on Rock Art and Cave Walls

DNA preservation on cave walls is highly variable, but scientists say their work is an important step on the path toward gaining a deeper understanding of our creative ancestors

Modern humans and our relatives have occupied Wonderwork Cave in South Africa for around two million years.

Early Humans May Have Used Fire 1.8 Million Years Ago, Nearly Doubling the Age of the Oldest Known Evidence for the Feat

In Wonderwerk Cave in South Africa, burned bones were found in a dirt layer associated with Homo erectus. The inhabitants probably hadn’t mastered fire-making, but researchers say they may have moved and maintained flames from a natural fire

A fossilized Homo naledi skull

New Research

Did These Prehistoric Primates Really Bury Just Their Female Dead Deep in a Cave?

Researchers say that the fossilized bones of “Homo naledi,” so far found exclusively underground in South Africa, lack a key genetic male marker

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.

New Research

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

An artistic rendering of the successfully hunted straight-tusked elephant, which would have been an incredible source of food for Neanderthals

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
