Shell, Beak, Tusk: Shared Traits and the Wonders of Adaptation
Written by Bridget Heos
They say there’s always more than one way to solve a problem, but some ways are better than others. Whether it’s tall ears, shells, beaks, or even glowing phosphorescence, the animal world is filled with examples of creatures who don’t share the same family tree but who do share important survival traits. In this fun, fact-filled look at convergent evolution, author Bridget Heos shows readers how some key survival problems are solved by some very different animals.
