Beneficial mutations happen quite frequently, but the world changes too fast for them to stick.

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 ...

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 ...

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 ...

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 ...

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 ...

Today, biologists taking a closer look at the animals located inside the Chernobyl Exclusion Zone (CEZ), which is about the size of Yosemite National Park, and investigating how decades of radiation ...
