According to Edward Drinker Cope, nineteenth-century paleontologist, fossil records show lineages become larger over millennia indicating that bigger is more successful. Though later scientists offered further support for Cope’s rule, from mammals to corals, paleontologists in the last century challenged such evidence. Gould, in particular, was dismissive of such a psychological artifact. Current more rigorous studies suggest the results are plain to see: being big provides a big advantage. And yet, the study continues Why isn’t Cope’s rule more of a rule? Laws of physics reveal that insects cannot grow to the size of Tyrannosaurus rex because their exoskeleton cannot support heavy loads of body mass. Furthermore, a small rat is probably better adapted to a certain niche. There is also the issue of surviving mass extinction though not everything can get small enough quick enough. I am already small so that isn’t a personal concern; still, each consecutive husband has gotten larger though I’m not sure why or what that reveals except it’s easier for Harold to reach for stuff on the top shelf rather than watch me, at fifty, climb on the kitchen counter, though last weekend he bought, for us both, a step ladder ruling out vulgar advantage.
