Mitochondria are known as the body’s “energy factories,” and their function is essential for life. Inside mitochondria, a set of complexes called the oxidative phosphorylation (OxPhos) system ...

Researchers found that ancient hominids—including early humans—were exposed to lead throughout childhood, leaving chemical traces in fossil teeth. Experiments suggest this exposure may have driven ...

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 ...

Humans were living in rainforests roughly 150,000 years ago, some 80,000 years earlier than was previously thought—and may have been an important center for early human evolution. This is the ...

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 ...

Researchers studied ancient tooth fossils and found that a gene mutation in modern humans (right) better protected them against lead and gave them an advantage over Neanderthals (left). Kyle Dykes / ...

A new study is shedding light on an important connection between human evolution and cancer. It reveals that some of the very genes that helped make our brains smarter are also being misused by cancer ...

Food processing has been a part of human adaptation since deep in the past. The softening and breaking down of food left its testimony on the human body. For example, the massive teeth of our early ...
