Re: If at first you don't succeed....skip sky diving.
why, e.g., would flying insects need larger wingspans in a more dense atmosphere?
They wouldn't, and anyway I'm not aware that the Earth did have a denser atmosphere then. Arthropods (and not just flying insects) back then did grow much larger than today but this was because the atmosphere contained a much larger proportion of oxygen.
