  • Snakes make biologists' hearts beat faster, too, but for a different reason: in evolutionary terms, they may be the most surprising group of vertebrates on Earth. Their long, legless bodies, it turns out, are the least remarkable thing about them. It's on the inside that snakes have made extraordinary changes. The story of how snakes evolved begins just over 100 million years ago, with a lizard or lizard-like reptile. Biologists are still debating about exactly which group the ancestor of snakes belonged to. Here, Holmes discusses how snakes have evolved in amazing ways.
