Mathematical rule found to have shaped bird beaks for 200 million yearsÂ
Bird beaks come in almost every shape and size â from the straw-like beak of a hummingbird to the slicing, knife-like beak of an eagle. We have found, however, that this incredible diversity is underpinned by a hidden mathematical rule that governs the growth and shape of beaks in nearly all living birds. Whatâs more,…
