A study is reframing a fundamental question in plant evolution: What made trees possible? Researchers from Cal Poly Humboldt, Yale University, the University of Hohenheim in Germany and the Czech Academy of Sciences set out to understand how trees evolved and what allowed them to

In cancer research, one person's junk is increasingly becoming another person's treasure. Scientists have uncovered new evidence showing how recently evolved "junk DNA" genetic elements can become integrated into ancient cellular pathways that regulate cancer. These findings may

A new analysis supports the previously overlooked "brain lag" hypothesis—the idea that, in some primate lineages, the evolution of larger body size preceded the evolution of larger brain size—while also building on that hypothesis by suggesting that some lineages' brain sizes the

The rhythm of human laughter appears to have deep evolutionary roots shared with chimpanzees, bonobos, gorillas, and orangutans. That ancient pattern may offer one of the clearest clues yet to how the vocal control needed for human speech gradually evolved.

The human brain evolved for a world of familiar faces, immediate threats and small social groups. But the world around us is changing far faster than human biology can keep pace. That mismatch may help explain some of the stress, loneliness and constant comparison people experien

What does a hantavirus do inside its rodent hosts? How do these viruses move through animal populations? And how is it that they cause almost no apparent symptoms in rodents, yet can be nearly fatal in humans? Specially Appointed Professor Hiroaki Kariwa has been studying hantavi

New research has begun to lift the lid on the global online trade in land crabs, leading scientists to call for closer monitoring and regulation to better understand any effects it may be having on native populations and global biodiversity. The study, published in Oryx, highligh

As this year’s invertebrate of the year competition launches, we join scientists studying last year’s winnerNominate your invertebrate of the yearWitek Morek is closely inspecting an old brick-and-flint wall on the Cambridgeshire campus of the Wellcome Sanger Institute.“We are go

Before the oldest dinosaur, before animals or even plants had expanded onto dry land, ancient relatives of starfish called crinoids, resembling stalked sea flowers, were among the first creatures to flourish in Earth's earliest coral reefs more than 450 million years ago. The stu

Scale in the universe is hard to understand from a purely human perspective. Many times, the math just doesn't sit well with our brains, which evolved to capture and process data about the world around us rather than grok the complexities of stellar dynamics and galaxy mergers. B

The evolutionary paths that created snatching forelimbs in insects multiple times moved in a similar direction but didn't end at a single solution. Kobe University research is pioneering a study of how organs with similar functions evolve, providing a new analytical approach to i

A newly discovered Happy-Face spider in the Himalayas closely resembles Hawaii's iconic species but evolved independently, according to DNA evidence. Its mysterious smile-like markings, many color forms, and unexpected link to ginger plants have scientists eager to learn how the
