Mauricio González-Forero, an evolutionary biologist at the University of St Andrews, in the U.K., is proposing a new theory to explain the massive growth of the human brain over its evolutionary history.

Climate change, such as warming and changes in precipitation patterns, affects the frequency and severity of harmful algal blooms (HABs) globally, including those of toxin-producing cyanobacteria that can contaminate drinking water.

Zebrafish in the pet trade are asymptomatic carriers of previously undescribed microbes, including a novel virus that causes hemorrhaging in infected laboratory fish, Marlen Rice from the University of Utah, US, and colleagues report in the open-access jo

Important scientific finds don't always come in the biggest, buzziest packages. Sometimes new discoveries come in little ugly rocks. Such is the case of a 6-centimeter-wide, nondescript mass of bone and teeth that helped a scientist at The University of

The theory of coevolution says that when closely interacting species drive evolutionary changes in each other this can lead to speciation—the evolution of new species. But until now, real-world evidence for this has been scarce.

A large fossil discovery has helped shed light on the history of dinosaurs in Wales. The find is reported in Proceedings of the Geologists' Association.

Fossils found on the shoreline of Lake Kariba in Zimbabwe represent a completely new dinosaur species. This remarkable find, named Musankwa sanyatiensis, marks only the fourth dinosaur species named from Zimbabwe. The research detailing this significant d

Researchers have developed a novel version of a key CRISPR gene-editing protein that shows efficient editing activity and is small enough to be packaged within a non-pathogenic virus that can deliver it to target cells. Hongjian Wang and colleagues at Wuh

Plants and the animals that eat them have evolved together in fascinating ways, creating a dynamic interplay of survival strategies. Many plants have developed physical and chemical defenses to fend off herbivores. A well-known strategy in flowering plant

Researchers have discovered a new distinctive and secretive snake species in the Hejaz region of Saudi Arabia.

We live in an ever-changing and growing world. Changing climates, emerging pests, and other environmental stressors put pressure on the cash crops that feed and fuel the world. As we race to meet the growing demand for sustainable and high-quality food an

Trout living in rivers polluted by metal from old mines across the British Isles are genetically "isolated" from other trout, new research shows. The work appears in Diversity and Distributions.
