Can an Irish elk beat a kangaroo? Can a Javan slow loris take an Iberian lynx? Do mythical animals have greater powers than real ones? What the heck are quokkas and numbats anyway?

Everyone who’s taking part in the 2015 MMM is right now finding the answers to those questions and more.

Mammal March Madness was founded just for fun by Harvard evolutionary biology professor Katie Hinde in 2013. It was more than fun. It completely took off.  Now she and three colleagues research the animals and run the game.

All set! It’s Cath Palug for the win!


We’d really love it if family and friends joined us!

Before you fill out your bracket, here are a few things you might want to know —

Battle outcome is a function of the two species’ attributes within the battle environment. Attributes considered in calculating battle outcome include temperament, weaponry, armor, body mass, fight style, and other fun facts that are relevant to the outcome.

Early rounds, the battle occurs in the better-ranked species’ habitat (home court advantage). BUT once we get to the ELITE EIGHT, battle location will be random: forest, semi-arid desert, intertidal zone, or snowy tundra.
