In these matters I bow to Paul Shepard.
 
As his Wiki states:
 Shepard's books have become landmark texts among ecologists and helped pave the way for the modern primitivist train of thought, the essential elements being that "civilization" itself runs counter to human nature - that human nature, as Shepard so eloquently stated, is a consciousness shaped by our evolution and our environment. We are, essentially, "beings of the Paleolithic".
Some of his most influential books are The Tender Carnivore and the Sacred Game, Nature and Madness, Coming Home to the Pleistocene, Where we Belong, and the Others.

In the classic joke about musical horrors, an explorer awaiting death at the hands of his captors in the jungle repeatedly asks the witch doctor what the pounding, ominous drums in the distance mean. He is told again and again: "When drums stop, very, very bad." Finally, unable to bear the hair-raising din any longer, the doomed explorer groans: "So what exactly does happen after the drums stop?" To which the witch doctor offers his mordant reply: "Bass solo."
