In the animal kingdom, a bigger body size, or biovolume, has often been found to go along with greater biological fitness -- that is, the ability to thrive and reproduce. This has led many biologists to speculate that, over time, natural selection has favored larger animals, and that animals have probably been increasing in size. It’s known as Cope’s Rule, after American paleontologist Edward Drinker Cope, who noticed in his study of fossils that some organisms -- especially mammals -- seemed to increase in biovolume over evolutionary time. But Cope’s Rule has been seen as more of a gu...
