The hidden mathematical formula that has defined the shape of the peaks of birds (and dinosaurs) for 200 million years

Have you ever wondered why the peaks of birds have such different but equally functional shapes? From the fine peak of a hummingbird to the sharpness of an eagle, these diverse structures share a surprising mathematical rule that has guided their evolution for millions of years. A group of researchers has revealed that this variety obeys, in most cases, a growing law known as “the cascade of powers,” a formula that has shaped not only the peaks …
