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 a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and ...

Analysis of the DNA and proteins of a range of animals has revealed that sperm’s molecular toolkit arose in our single-celled ...

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 ...

What genetic changes are responsible for the evolution of phenotypic traits? This question is not always easy to answer. A newly developed method now makes the search much easier. With its powerful ...

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 ...

Online abstracts and tables of contents are HTML encoded, articles are in portable document format (pdf). Also available by subscription via the World Wide Web ...

A new study led by the University of Oxford has found evidence that kissing evolved in the common ancestor of humans and ...

A new study uncovered fresh chemical evidence of life in rocks more than 3.3 billion years old, along with molecular traces showing that oxygen-producing photosynthesis emerged nearly a billion years ...
