The earliest tetrapods, or "four-footed" animals, were mammal-like reptiles that evolved before the rise of the dinosaurs and ranged from mouse-sized to cow-sized. Today the tetrapods include the reptiles, the amphibians, the birds, and the mammals—including humans. Though the fish aren't classified as tetrapods, it's quite possible that our own limbs began as paired fins hundreds of millions of years ago.
