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 ...

With a rate of mutation 35 percent higher than random chance, this previously unknown weakness could be a major vector for inherited disease.

The analysis revealed that about 2 per cent of sperm from men in their early 30s contained disease-causing mutations. That ...

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 ...

All of living nature is subject to evolution. Living organisms are exposed to selection pressure, which means that those that are best able to assert themselves survive. This natural selection process ...

Changes in the key antigenic regions of H3N2 viruses suggest that the upcoming flu season may require closer attention to ...

Many people hold the view that evolution in humans has come to a halt. But while modern medicine and technologies have changed the environment in which evolution operates, many scientists are in ...

Researchers report that phage resistance in ocean bacteria can alter growth, metabolism and sinking behavior, revealing a ...

A zoo outbreak shows how SARS-CoV-2 rapidly evolves in animals, revealing why monitoring COVID-19 in wildlife is vital for ...
