How Gigantic insects, plants evolved in Devonian, Dragonflies // evolution series, book 3
Last revision was 18Sep2021. This is AP's 104th book of science.
The Devonian geological age had gigantism of plants and animals. Some ferns and horsetails grew to the size of trees and many insects grew to a huge size, such as Dragonflies the size of a human arm. Several attempts have been given to account for this gigantic size, but none seem plausible. So I offer a theory to explain it, because it has to be some physical characteristics of Earth itself, during the Devonian to account for gigantism in both plants and animals.
