FRAGMENT FROM NATURE ponders the issue of gigantism during certain periods of evolution, when insects, plants, and animals gained enormous sizes.

How were they differently adapted to overcome their plumbing? And were they structurally different so that they could carry a greater body mass on delicate wings?
