To apply a neutral model of evolution to a population, Hahn explained, you don’t have to know how strong selection is, how large the population is, whether mutations are dominant or recessive, or ...

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 ...

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 ...

While evolution involves changes in organisms that we can observe, they undergo evolution at a deeper level, too. That is, changes affect the "letters" (four different types of chemical units) in the ...

Extrinsic and intrinsic factors impact diversity. On deep-time scales, the extrinsic impact of climate and geology are crucial, but poorly understood. Here, we use the inner ear morphology of ruminant ...
