Millions of sperm do not always compete alone--some species send them into action as coordinated teams. A sweeping evolutionary study found that this cooperation is widespread among arthropods and has repeatedly emerged and vanished over hundreds of ...

Ancient seafloor sediments have revealed a surprising twist in how the Atlantic's massive circulation system works. During a cold period about 3.4 million years ago, the flow of warm, salty water from the Indian Ocean into the Atlantic nearly shut .. ...

A spectacular fossil site in Canada contains 567-million-year-old creatures that may represent some of the earliest animals to move, reproduce sexually, and develop recognizable body plans. The discovery pushes key evolutionary milestones back by up ...

An exceptionally preserved snake fossil from Brazil reveals that early snakes were far more diverse than scientists once thought. Detailed brain reconstructions show that Tametara mirim was adapted for burrowing, while another ancient snake was ...

A massive crocodilian capable of attacking dinosaurs has been brought back to life as the first scientifically accurate mounted skeleton of Deinosuchus schwimmeri. The 31-foot replica at Georgia's Tellus Science Museum was built from detailed fossil ...

Historic wildfires scorched huge areas of Spain and France, with one Spanish blaze burning an area about the size of New York City and a French fire generating a rare, towering fire cloud. A dangerous combination of lush winter growth, severe heat, . ...

Fossilized dinosaur bones from Wyoming are offering a rare glimpse into the feeding behavior of Tyrannosaurus rex. Researchers examined more than 3,000 bones dating back 72 to 66 million years and found just 12 with possible tooth traces, including . ...

Scientists have uncovered a surprising way that "jumping genes" may move between species and speed up evolution. While these mobile genetic elements were thought to travel mainly inside viruses or plasmids, researchers found circular intron RNA from ...

A tiny 518-million-year-old sea creature has revealed the earliest known evidence of the structures that eventually became spiders' fangs. Hidden inside the fossil were pincerlike limbs and preserved soft tissues that help explain how the ancestors . ...

Animal bones preserved in South Australia's underwater caves reveal distinctive clues shaped by darkness, algae, bacteria, and other environmental conditions. The findings give scientists a powerful new way to reconstruct how ancient megafauna ...
