User blog comment:CreatorTheta/Human Evolution Theory in RWBY/@comment-11384103-20140624070915

Well with the growth issue, it is still possible that everything was brought up to size as people grew bigger. As well as the fact that gigantism is a defect, not a eventual evolution of the species. Gigantism should not of happened in one generation as a defect, which is why they die early and such. Overtime evolution for them to grow is possible and useful as even now, we as a species are growing taller and taller each generation due to the abundence of food and resources and the need for more oxygen as large lungs hold more oxygen. But remember, we don't know whether they are human sized, which seems less likey with this theory, or that they are taller super human beings with everything scaled up as they evolved.
