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 ...

Scientists studying how microbes evolve have long assumed that nearly all new genetic mutations get passed down at a predictable pace and usually without either helping or hurting the microbe in ...

COLUMBUS, Ohio – The established conservation practice of relocating animals from large, genetically diverse populations to small communities of inbred endangered species may risk introducing more ...

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 ...

ANN ARBOR—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 ...

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 ...

New study demonstrates how high-affinity B cells 'bank' their best traits instead of rolling the dice and risking deleterious mutations, with implications for better vaccine design. A vaccine's ...

KRAS is the most frequently mutated oncogene across all human cancers. Although different KRAS mutations have long been thought to exert the same cancer-driving effects, a new study led by UT ...
