All vertebrates have the same basic body plan: Head, spine, four appendages. Those appendages vary greatly in size, shape, and function, of course—from fins to wings, arms, and legs—but a new genetic analysis shows that genes that control development at the ends of the appendages share a deep evolutionary history.
