An ancient DNA analysis of the remains of several mastodons, including those which roamed along the Pacific and Atlantic coasts of North America, has revealed the Ice Age giants migrated vast distances in response to shifting climates and were far more genetically diverse than previously known.

Hidden for 95 million years beneath layers of sediment, the remarkablywell-preserved skull of an ancient legged snake species — Najash rionegrina — has now revealed a chapter of evolutionary history that’s been missing for decades.

Columbian mammoths in Mexico are genetically different from those in the U.S. and Canada, surprise DNA study reveals.

A new study suggests a habitable past and signs of ancient microbial processes on Mars.
