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 ...

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

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

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 ...

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 ...

These sequences are extremely prone to mutations and rank among the most functionally important regions in the entire human ...

Research on SARS-CoV-2 in zoo tigers, lions, and hyenas shows rapid viral evolution and adaptation, offering insights into cross-species transmission dynamics.

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