Chemical traces preserved in ancient rocks indicate that marine environments were deteriorating long before the catastrophe that wiped out vast numbers of species at the end of the Triassic period, ...

Analyzing 1.75-billion-year-old microfossils from ancient Australian seabeds, paleontologists say ancient eukaryotes — the ancestors of every plant, animal and fungus — huddled in oxygenated seafloor ...

New research from the University of Oxford and the University of Reading suggests bipedalism and expanding brain size helped drive the overwhelming dominance of right-handedness in humans. “In all ...

Space debris — ranging from defunct satellites and discarded rocket stages to fragments from collisions — poses an ever-increasing threat to active spacecraft and human spaceflight. New research shows ...

A landmark study of several butterfly lineages and a day-flying moth in South America shows that convergent evolution — when unrelated species arrive at the same solution — isn’t just a coincidence; ...
