Human Origins

In 2025, researchers watched an interstellar comet, learned about human origins and traced the spread of measles.

The Ten Most Significant Science Stories of 2025, From Medical Breakthroughs to an Interstellar Visitor

All year long, these moments captivated the public, demonstrated dangerous trends, and pushed research and innovation forward

New Research

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

Stunningly Well-Preserved Neanderthal Skull Suggests the Species’ Large Noses Weren’t Adapted for the Cold

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.

Cool Finds

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

Could These 80,000-Year-Old Stones Be the World’s Earliest Known Arrowheads?

A new study suggests that fragments unearthed at an archaeological site in Uzbekistan look like other examples of arrowheads created thousands of years later

Early Humans Moved Stones Long Distances to Make Tools 600,000 Years Earlier Than Thought

A new study takes another look at some of the oldest known stone tools and suggests their makers transported materials for up to eight miles

Researchers suggest 140,000-year-old child remains from Israel's Skhūl Cave may have belonged to a Homo sapiens-Neanderthal hybrid.

A Child’s Skull That Has Long Confounded Archaeologists Might Be a Human-Neanderthal Hybrid, Study Suggests

According to new CT scans and models, parts of the 140,000-year-old skull resemble those of modern humans, while the jaw appears to be more similar to those of our extinct relatives

Researchers found small Homo erectus fossils among other animal remains. 

A Massive Underwater Fossil Find Includes Remains From Ancient Human Ancestors

More than 6,000 animal fossils were found in Indonesia, and two of them belong to Homo erectus

The team didn't use any maps throughout their 45-hour trip.

Scientists Built a Canoe Using Only Prehistoric Tools. Then They Sailed the Dangerous 140-Mile Route Early Humans Traveled 30,000 Years Ago

Five paddlers journeyed from Taiwan to Japan’s southern Yonaguni Island in 45 hours. Their efforts provide new insights into prehistoric mariners’ tools and techniques

The Dragon Man skull, described as Homo longi in 2021, belongs to a Denisovan, according to new research.

Iconic ‘Dragon Man’ Skull Offers First Glimpse of What a Denisovan’s Face Looked Like, New Genetic Studies Suggest

The mysterious ancient humans were only known from fossil fragments. Now, two papers argue a skull uncovered in China belongs to this group, after examining preserved DNA and proteins

The Schöningen spears on display in Germany

New Research

Nimble-Minded Neanderthals May Have Used These Wooden Spears to Hunt 200,000 Years Ago

New research shows that the weapons found in Germany are much younger than previously thought, suggesting they were made by skilled Neanderthal craftspeople

Researchers extracted ancient proteins from the bone and tooth enamel.

Mysterious Jawbone Found at an Antique Shop in Taiwan Belonged to a Male Denisovan, Scientists Say

The fossil, called Penghu 1, is one of the few known pieces of physical evidence from the Denisovans, extinct relatives of modern humans. It suggests the species lived in diverse environments

Archaeologists found 15 skeletons in a rock shelter in southwest Libya, including two naturally mummified women who died roughly 7,000 years ago.
