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 ...

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 bird swoops toward a bright orange-and-black moth resting on a leaf in the Amazon. It pulls up at the last second. The ...

A genetic “cheat sheet” allows different species to display the same warning patterns.

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 ...

Have the canines acquired strange mutations living near the power plant?

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 ...

During the early stages of a pandemic, viruses tend to evolve in ways that enhance their ability to reproduce and spread, ...

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 ...

Researchers at the University of Oregon have developed an artificial intelligence tool that can read genetic code the way ...
