A lost chapter in human evolution has been revealed after an analysis of modern DNA found that we come from not one but two ancestral populations—ones that drifted apart and later reconnected long ...

Fossils unearthed in Ethiopia are reshaping our view of human evolution. Instead of a straight march from ape-like ancestors to modern humans, researchers now see a tangled, branching tree with ...

Human evolution is often told as a tidy story of adaptation, yet some of our most familiar body parts still defy straightforward explanation. From the jut of the human chin to the curve of the outer ...

Human fossils uncovered in a cave at the Thomas I quarry near Casablanca are offering fresh insight into a critical phase of ...

Scientists have uncovered new evidence suggesting that autism may have it roots in how the human brain has evolved. "Our results suggest that some of the same genetic changes that make the human brain ...

This has been quite the wild year in human evolution stories. Our relatives, living and extinct, got a lot of attention—from new developments in ape cognition to an expanded perspective of a ...

Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift—driven not by genes, but by culture. "Human evolution seems to be changing ...

Human evolution’s biggest mystery, which emerged 15 years ago from a 60,000-year-old pinkie finger bone, finally started to unravel in 2025. Analysis of DNA extracted from the fossil electrified the ...

A composite view of the Earth constructed by NASA from multiple satellite images Editor at Large Human evolution is a story writ slow. It’s been about 3.8 billion years since life on Earth emerged and ...

Throughout most of human history, evolution progressed slowly. Small genetic changes took thousands of years to permeate populations. Natural selection was intentional, reactive, and gradual. However, ...

Autism spectrum disorder (ASD) may be the result of millions of years of evolution. Rapid neuronal evolution in humans is likely ASD’s genetic cause, new research suggests. Though autism can cause ...
