In simple terms: a mutation is a stable change in genetic sequence that can be copied when cells or viruses replicate. Most mutations have no detectable effect, some contribute to disease, and a small ...

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 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 ...

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 ...

The model does not rely on the infinite sites approximation (that a specific mutation newly arises in only one cell at any instant) in contrast to related models. The results become increasingly ...

The rhizome concept proposed by Gilles Deleuze and Félix Guattari offers a novel perspective on the organization and interdependence of complex constellations of heterogeneous entities, their mapping ...

A major research study is challenging one of evolution’s most influential ideas: that most genetic changes that become permanent are essentially neutral. Researchers at the University of Michigan ...

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 ...
