Mammals were adapting from life in the trees to living on the ground before dinosaur-killing asteroid
The study, published today in the journal Palaeontology, provides fresh evidence that many mammals were already shifting toward a more ground-based lifestyle leading up to the asteroid’s impact.

Through analysis of sulfur isotopes in the well-studied HK-1 drill core, researchers showed that Earth’s largest mass extinction event didn’t wipe out life on land with a single massive volcanic event. Rather, the die-offs happened regionally and progressively over hundreds of thousands of years 🌍💔🌋📉
