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 ...

For more than half a century, many biologists have leaned on the neutral theory of molecular evolution to explain how DNA and proteins change over time. The idea grew from early work in the 1960s, ...

Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of Darwin. One focus of current debates is whether adaptive evolution relies ...

LOGAN, UTAH, USA – Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of Darwin. One focus of current debates is whether ...

A study published in Nature Ecology & Evolution reveals a surprising evolutionary insight: sometimes, losing genes rather than gaining them can help bacterial pathogen survive and thrive. The study ...

Here’s what you’ll learn when you read this story: In Lake Malawi, Africa, fish known as cichlids have been evolving astonishingly fast—the lake hosts at least 800 species of them. Researchers who ...

This research topic explores the integration of multiscale landscape genomics to uncover the intricacies of adaptive evolution, particularly in response to ...

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 ...
