A 15-pound honey badger can survive a cobra bite that would kill a full-grown man in under two hours. Then it finishes eating the snake. A biology grad student at the University of Minnesota wanted to know how. She needed badger blood to find out, and the only samples she could get were from two American zoos in San Diego and Indiana. What she found in the DNA was one tiny change. There's a small socket on your muscle cells that your nerves plug into to tell your muscles to move. Cobra venom kills you by jamming that socket shut, so your lungs stop working. The honey badger's socket has a swapped-out amino acid that gives it a positive electrical charge. Cobra venom is also positively charged. Like magnets pointing the wrong way, the venom gets pushed off before it can lock in, and the muscles keep firing. The same workaround showed up separately in hedgehogs and pigs. Mongooses got there too, with a slightly different molecular trick. Four different animals with no shared ancestor all arrived at the same solution because venomous snakes kept biting them for millions of years. That only covers snakes like cobras and mambas. Puff adders work differently, destroying tissue instead of paralyzing muscle, and the DNA trick doesn't help there. So when a puff adder lands a solid bite, the badger collapses into a kind of coma for two or three hours. Then it wakes up groggy and eats the snake anyway. The skin is maybe the unfairest part of all this. It's about a quarter inch thick, rubbery, and so loose it fits like a wetsuit two sizes too big. A lion can clamp its jaws on a honey badger and the badger will twist halfway around inside its own skin and start clawing the lion's face while still in its mouth. Bee stingers barely get through. Porcupine quills don't either. Which brings us back to the bees in that photo. They're annoying. A few sneak through to the face, and enough stings have killed honey badgers in the wild. Honey badgers still die. But they're running three different defense systems at the same time, and one of them is a genetic lottery ticket evolution has pulled four times.
