““In the forests man has always deteriorated; human evolution has made progress only in the open and in the higher latitudes. The cold and hunger of the open lands stimulate action, invention, and resourcefulness. While these Andonic tribes were developing the pioneers of the present human race amidst the hardships and privations of these rugged northern climes, their backward cousins were luxuriating in the southern tropical forests of the land of their early common origin.””
