Author's Note: 10 Worst Adaptations in the Animal Kingdom

There's something a little uncomfortable about calling an animal adaptation "bad." As the zoology professor and hyena expert Kay Holekamp points out, the fact that hyenas have evolved -- and kept -- a delivery system that could suffocate young implies that the benefits outweigh the costs [source: Hyena Research Special Report.] It's possible the same could be said for any evolutionary adaptation we've identified as the so-called "worst."
