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

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 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 ...

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 ...

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 ...

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 ...

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 ...
