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 ...

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 ...

Evolution isn’t a single, straightforward process – it works in several distinct ways. From species splitting apart over time ...

In the spring, ants are once again hard at work. Beyond their everyday presence, ants are also key model organisms in cutting ...

A study published in the Proceedings of the National Academy of Sciences by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not ...

A new platform for studying mtDNA mutations implicated in human disease could help accelerate treatments for mitochondrial ...

What causes autoimmune disease? A new study finds that somatic mutations in immune checkpoint genes like PDL1 trigger the ...

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 ...

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 ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. Many people hold the view that evolution in humans has come to a halt. But while modern medicine and technologies have ...
