Adaptive evolution arises when heritable genetic variation confers a fitness advantage under changing environmental or ecological conditions. Central mechanisms include the generation of variation ...

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 ...

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 ...

When Charles Darwin developed his theory of evolution in the mid-19th century, he figured this fundamental process took place very slowly over geological timescales, taking millions of years. But is ...

In Lake Malawi, Africa, fish known as cichlids have been evolving astonishingly fast—the lake hosts at least 800 species of them. Researchers who sequenced the genomes of these fish found that ...
