Every year, March Mammal Madness asks "Who would win?" between two animals in "an absurdly complex and wonderfully nerdy way." NCSE talks to Katie Hinde, the founder of March Mammal Madness and associate professor of evolutionary biology and the Senior Sustainability Scientist at Arizona State University. Hinde, interviewed by NCSE Executive Director Amanda L. Townley, discusses the origins of the incredibly popular, worldwide phenomenon, why so many people — including thousands of educators and their students — love it, and the importance of science communication and outreach.
