A new study cross-examines classic hypotheses about the coevolution of butterflies with flowering plants and moths with bats, their key predators. The findings show flowering plants did drive much of these insects' diversity, but in a surprise twist, multiple moth lineages evolved 'ears' millions of years before the existence of bats, previously credited with triggering […]

The discovery of a nearly complete dromaeosaurid Saurornitholestes langstoni specimen is providing critical information for the evolution of theropod dinosaurs, according to new research.

Researchers studied fossilized Moroccan Ampyx trilobites, which lived 480 million years ago and showed that the trilobites had probably been buried in their positions -- all oriented in the same direction. Scientists deduced that these Ampyx processions may illustrate a kind of collective behavior adopted in response to cyclic environmental disturbances.

That's exactly what happened in April 2010 when Eyjafjallajokull, a volcano in Iceland, erupted and disrupted air travel in Europe for 6 days. […]

Mars once had salt lakes that are similar to those on Earth and has gone through wet and dry periods.

Scientists have detected primordial chemical signatures preserved within modern kimberlites, according to new research. The results provide critical insight for understanding the formation of Earth.
