Evo in the news How did early mammals chew? - May, 2019 Unless you have a toothache, it's easy to take chewing for granted. We crunch through foods like nuts and fruit without thinking much about the anatomical equipment that makes it happen. But we know from fossils that our earliest mammalian ancestors didn't have a single lower jaw bone like we do today; instead, they had left and right jaw bones that could move independently. How did early mammals chew? And how has mammalian chewing evolved over the past 250 million years? Recent research reveals clues. Read the rest of the story here | See the Evo in the News archive

A Pleistocene Puzzle: Extinction in South America In this comic, you'll follow the investigation of scientists Maria and Miguel as they solve a paleontological mystery. About 11,000 years ago, more than 80% of the large animal species in South America went extinct. Why did it happen? Maria and Miguel study an area in Chile called Ultima Esperanza. They discover many different lines of evidence that point to a warming climate and the arrival of humans as key causes of the extinctions.		A Place for Life: A special astronomy exhibit of Understanding Evolution Biology and paleontology provide an increasingly detailed picture of the evolution of life. Natural selection has resulted in a huge range of organisms living in a multitude of environments, and the geological record shows us how the Earth as a whole has changed over time. To understand the stage on which the evolution of life plays out, however, we must turn to astronomy.
