« on: 03/06/2013 21:13:27 »I always wondered why insects didn't get bigger. Is an exoskeleton unstable beyond a certain size? Is their respiratory system not efficient enough to get oxygen to all the the tissues beyond a certain size? Well, anyway, I'm glad they didn't.I think when they are scaled up , although the new dimensions can hold more weight , the forces required is cubed or something like that. Watched interesting tv program a while ago. Also glad here that the design does not scale up. An ant the size of a t-rex would rule the world, well if it had its buddies.
