Mammoths are probably the most famous prehistoric proboscidean, but for much of their history, proboscideans were missing one of the key features of modern elephants: a long, grasping trunk. So, how did we get here? New video on YouTube now! 🦣

For some reason, animals keep evolving into things that look like crabs, independently, over and over again. What is it about the crab’s form that makes it so evolutionarily successful that non-crabs are apparently jealous of it?
