How did massive volcanic eruptions, inland seas, and land bridges pave the way for life?
By watching a population of deer mice shift in the span of a single generation, scientists have captured evolution in action, connecting genes to survival in the wild.
Their closest relatives hide in burrows to ambush their prey. But Ozaena beetles have taken a different tack: infiltrating ant nests.
By fine-tuning the expression of a similar set of genes, mammals, birds, frogs, and fish may have all capitalized on a common toolkit in the transition to monogamy.
Armored ankylosaurs like Panoplosaurus and Euoplocephalus had living air conditioners built into their noses, protecting their tiny brains from overheating.
In a first, scientists have found that viruses that prey on microbes can understand the lingo of bacterial conversations—and may use the intel to time their attacks.
The first complete skeleton reconstruction of Thylacoleo carnifex, the “marsupial lion,” illuminates how this bizarre carnivore moved and ate.
After discarding their teeth, the ancestors of today’s filter-feeding whales may have fed by suction before evolving baleen.
