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.

This Triassic gliding reptile (Icarosaurus siefkeri) evolved to sport extended ribs that support its gliding membrane, Csotonyi writes on his website; as such, I. siefkeri and "the living flying dragon (Draco volans) are an excellent example of convergent evolution, in which relatively unrelated organisms under similar selection pressures independently evolve similar characteristics," he writes.

Smilodon and Thylacosmilus, an example of convergent evolution illustrated by Carl Buell.    “Under certain conditions, two lineages will evolve into very similar-looking forms. The top animal is a saber-toothed cat, related to lions and tigers. The bottom one is a marsupial, more closely related to kangaroos and opossums.”
