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 ...

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

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 ...

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

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 ...

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

A new computer model suggests that the process of evolution can get better at evolving in the face of environmental change. When you purchase through links on our site, we may earn an affiliate ...
