How the Snake Lost Its Legs: Curious Tales from the Frontier of Evo-Devo is a 2014 book on evolutionary developmental biology by Lewis I. Held, Jr. The title pays homage to Rudyard Kipling's Just So Stories,^[1]^[a] but the "tales" are strictly scientific, explaining how a wide range of animal features evolved, in molecular detail. The book has been admired by other biologists as both accurate and accessible.
