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 ...

A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the process differed from the evolution of chimpanzees. For the study, published ...

The human body is a machine whose many parts – from the microscopic details of our cells to our limbs, eyes, liver and brain – have been assembled in fits and starts over the four billion years of our ...

(Reuters) -Researchers have unearthed tooth fossils in Ethiopia dating to about 2.65 million years ago of a previously unknown species in the human evolutionary lineage, one that lived in the same ...

What did researchers find? A 1.6-to-1.5-million-year-old skull from Ethiopia combines features from two different stages of ...

What will humans be like generations from now in a world transformed by artificial intelligence (AI)? Plenty of thinkers have applied themselves to questions like this, considering how AI will alter ...

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, ...

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 ...

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 ...
