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 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 ...

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

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 ...

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 ...

Understanding the mutation and evolution of viruses (such as SARS-CoV-2) is crucial for effective public health management and response. Traditional epidemiological models often assume that viral ...

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 ...

The SIRSVIDE model developed by Professor Jian Lu's research group provides a comprehensive framework for studying viral epidemiology and evolutionary dynamics. The simulation results reveal that ...

Forbes contributors publish independent expert analyses and insights. Andréa Morris reports on emergent intelligence in diverse systems. “Where are all the genetic cures?” asks Denis Noble, a ...

Researchers published a new study, “Ongoing chromothripsis underpins osteosarcoma genome complexity and clonal evolution,” in Cell that they say solves the mystery of what drives the genomic ...

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