New research challenges the long-standing idea that most fixed genetic mutations are neutral. For many years, scientists studying evolution have believed that most genetic changes influencing how ...

For more than half a century, many biologists have leaned on the neutral theory of molecular evolution to explain how DNA and ...

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 ...

Convergent evolution—where distinct species independently evolve similar traits or functions, such as the wings of birds and bats—has long fascinated biologists. Now, a research team led by Prof. Zou ...

Understanding molecular diversity is fundamental to biomedical research and diagnostics, but existing analytical tools struggle to distinguish subtle variations in the structure or composition among ...

Aim: Globally, arthropod biodiversity is under threat, with increased risk of species-level extinctions, and this threat is particularly acute on oceanic islands. A fundamental first step towards ...

By adapting techniques originally used to study ancient DNA from archaeological specimens, researchers at the University of Chicago were able to recover genetic information from nearly century-old ...
