It’s no secret that animals and insects from the time before man were over-sized and intimidating – we have enough fossils in archeological museums spanning the globe to prove that, but what caused the significant decrease in size from those creatures compared to the creatures of our time?
The study was conducted using a variety of insects – dragonflies, cockroaches, etc., and a surprising discovery was made. When subject to higher levels of oxygen, dragonflies grew considerably from their average size, nearing the 27 inch wingspan of the ancient dragonflies of the Paleozoic era. As it turns out, the higher the oxygen level, the larger the dragonfly grew to be.
