A study has traced thousands of conserved regulatory elements back 300 million years, revealing deep principles of plant genome evolution—a discovery that could pave the way for more precise ...

Lines of bacterial genome sequences are made to evolve independently by introducing high-activity insertion sequences, each simulating decades of evolution in the wild in just weeks. The genome ...

The sequencing of the genomes of a spider from the mainland (Dysdera catalonica, left) and one from the Canary Islands (Dysdera tilosensis, right) opens a new perspective for understanding how genome ...

Ancient survival strategy: Flowering plants duplicated entire genomes during at least nine major environmental crises over 150 million years. Polyploidy under stress: Polyploids often struggle in ...

A recent paper provides an updated perspective on the evolutionary history of chelicerates—a diverse and ecologically significant group of arthropods that includes spiders, scorpions, mites, and ...

New research is shaking up our understanding of evolution by revealing that some species may not evolve gradually at all. Instead, scientists discovered that certain marine worms experienced an ...

As mist lingers over a Swedish fjord lined with towering, forested cliffs, a group of scientists collect mud from the bottom of the turquoise-colored waters. They’re after brittle stars—marine animals ...
