Shell, Beak, Tusk: Shared Traits and the Wonders of Adaptation - Hardcover

by Bridget Heos (Author)

We think of evolution as a tree with branches that make clear, linear sense--with one animal and its traits clearly derived from one that came before it genetically. But what about animals who share key traits but aren't on the same family tree? This is called convergent evolution, and it's the big idea that Bridget Heos tackles in a kid-friendly way in Shell, Beak, Tusk.

From mammals to reptiles, and everything in between, Heos manages to make some intriguing comparisons--and bring to life theories of evolution and convergentevolution in bite-sized, easily digested chunks of fun facts, illustrated with full-color photography throughout.
