Biologists are closing in on a puzzle that seems to turn classic evolutionary logic inside out, yet may be so common that it ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

The study of experimental evolution in Escherichia coli has provided unprecedented insights into the mechanisms of adaptive mutations, elucidating how populations diverge and optimise their fitness ...

A groundbreaking study published in this week’s issue of PNAS by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not randomly but more ...

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 ...

Discover interesting facts about how evolution works, the different patterns that can emerge from evolution, how quickly organisms can evolve, and whether evolution is a random or ordered process When ...

On a recent summer evening, my wife was busy page-turning our copy of the weekly New Yorker magazine. Like many of us, the cartoons were the main attraction with occasional stops at articles that ...

The prothrombin gene mutation increases your risk of severe blood clots. Medications, regular checkups, and healthy lifestyle habits can help reduce this risk. The prothrombin gene plays a crucial ...
