Evo in the news Standing on two feet or four: Switchbacks in dino evolution - October, 2018 Last month, researchers announced the discovery of an enormous dinosaur in South Africa. Ledumahadi mafube weighed as much as two elephants and lived around 200 million years ago. Scientists were surprised to find that such a big dinosaur was so ancient. L. mafube was the largest dinosaur known from its time, and the closely related sauropods (true behemoths which grew to be seven times as large as L. mafube and included the largest land animals ever) achieved their massive sizes much later. Evidence also suggests that this new dinosaur walked on four legs -- a finding that highlights the fact that evolution represents a blossoming of diversity, not a linear march of “advancement” along a set track.

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.
