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

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

The brown trout were likely introduced to guarantee a food source if reindeer hunts were unsuccessful, according to a new study.

Hunter-Gatherers Brought Trout to a Norwegian Mountain Lake 7,000 Years Ago, the Earliest Known Example of Humans Translocating Fish

Researchers have long known that the animals were introduced into the region’s high-altitude bodies of water, but they weren’t sure when it happened or whether humans had a hand. Analyses of recently discovered ancient fish traps provide new clues

Fruit grows on a native avocado tree in southern Mexico

Ancient Genes Reveal That Big, Bright Avocados Were Carried Through the Americas Thousands of Years Ago

People brought large avocado seeds from South America to Central America, kicking off a burst of diversity for the fruit

Known as Yowjab to Indigenous Australians, the inshore reef covers about 100,000 acres.

For Three Hours Every Day, Open Ocean Transforms Into Australia’s ‘Ghost’ Reef

An isolated wonder some 1,200 miles from the nearest city, Montgomery Reef disappears as quickly as it appears, mirroring the supposed vanishing of its original owners, a tribe of Indigenous giants

The exumed remains were reburied in caskets in 2022.

Thousands of Kidnapped Africans Died on an Island in the Atlantic After Being Rescued From Slave Ships. Evidence in Their Teeth Traces Their Journeys

Remains in the graves of St. Helena, where the British military housed “liberated” enslaved Africans, contain isotopes from inland Angola and Zimbabwe

Princess Ita was buried with this dagger.

Did These Ancient Egyptian Princesses Wield Weapons and Train in Martial Arts, Just Like the Men of Their Time?

A new analysis of their bones suggests they were buried alongside arrows, maces and daggers because they had repeatedly used those weapons in life

Kazakhstan’s Iron Age ‘Golden Man’ and Other Elite Scythians of Eurasia Inherited Their High Social Status, Ancient DNA Suggests

Researchers have long wondered whether upper-class members of the ancient nomadic warriors earned their social status through individual achievements or birthright

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

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

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

Cool Finds

A Century After Causing Controversy, Red Cave Markings in Wales Are Classified Again as Britain’s Oldest Rock Art

The team of scientists used modern dating methods to confirm an old hypothesis by the rock art’s initial discoverers

Groundbreaking DNA Analysis Identifies 1.3 Million Living Relatives of Colonial Maryland’s Earliest Settlers

Experts compared DNA from 49 skeletons buried in a cemetery in St. Mary’s City to genetic data shared by 11.5 million 23andMe users. They also identified what may be the remains of the colony’s second governor

The procedure was likely extremely painful. But, afterward, the Neanderthal continued chewing with the tooth, which suggests they felt some relief.

New Research

Neanderthals Got Cavities, Too—and New Research Suggests They Drilled Into Their Teeth to Treat Them, Just Like Modern Dentists

Researchers unearthed a 59,000-year-old Neanderthal molar that shows signs of dental surgery, a discovery that pushes back the earliest evidence of dental work by roughly 45,000 years

Kenya's Great Rift Valley

East Africa Might Break Off From the Continent Sooner Than Scientists Thought—and a New Ocean May Fill the Gap

A new study suggests that a rift in Kenya and Ethiopia has reached a critical stage in the split-up process, and that water may flood it in a few million years

A full-scale reconstruction of the 1738 Fort Mose was built in 2025 after decades of planning and archaeological research.

The Little-Known Story of the Enslaved Africans Who Found Freedom in the European Fight Over North America

Long before the famous Underground Railroad, those seeking freedom from slavery traveled on foot, by boat and under cover of darkness to Fort Mose in Spanish-controlled Florida

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

New Research

These 12,000-Year-Old Scraps of Elk Hide May Be the World’s Oldest Known Examples of Sewing

Indigenous groups in present-day Oregon stitched the fragments together using cord made from plant fiber and animal hair. Experts think they may have been part of a garment, bag, container or portable shelter

Treponema pallidum is a spiral-shaped bacterium that currently exists in three closely related forms, one of which causes syphilis. 

Anthropologists Recover DNA of Syphilis-Causing Bacterium Relative From 5,500-Year-Old Human Remains, the Earliest Ever Found

The findings represent the oldest complete set of genetic information from this bacterial group and shed light on its evolutionary history
