Earl didn’t even attempt to answer that one. “Have you ever heard of a man named Raymond Dart?”
Louis told him he hadn’t.
“Raymond Dart was an Australian anthropologist and comparative anatomist. A true giant in the field. In 1924 he discovered the fossil remains of Australopithecus in a South African limestone quarry. In time, he also discovered more fossils of this extinct hominid, along with great heaps of fossilized bones that were the prey of the Australopithecine. He also discovered crude weapons such as clubs made from antelope bones and knives fashioned from jawbones, as well as heaps of animal bones and baboon skulls which bore the marks of death blows from these very weapons. As did the skulls of other Australopithecines. Evidence that was supported by forensic experts who examined the remains. The dawn of organized murder, Louis! A quarter of a million years before man! From this Dart theorized that we evolved not from a gentle vegetarian ape as established paleoanthropology would have it, but from a savage, predatory ape with a lust for killing. It was called the “Killer Ape” theory. He perpetuated it in his paper, ‘The Predatory Transition from Man to Ape.’ In the paper he said and I quote verbatim: ‘The blood-bespattered, slaughter-gutted archives of human history from the earliest Egyptian and Sumerian records to the most recent atrocities of the Second World War accord with early universal cannibalism, with animal and human sacrificial practices or their substitutes in formalized religions and with world-wide scalping, head-hunting, body-mutilating and necrophiliac practices of mankind in proclaiming this common bloodlust differentiator-this predacious habit, this mark of Cain-that separates man dietetically from his anthropoidal relatives and allies him rather with the deadliest of Carnivora.’ Well, don’t you see, Louis? Don’t you grasp it?”
Louis was way too tired for thinking, for anything this heavy. “We evolved from a killer ape, I guess. Not that I’m really surprised.”
“ Yes, basically,” Earl said, very excited to be lecturing once again. “The innate depravity of our species comes directly from the killer ape. Civilization is only an attractive cloak, for beneath we are murderous beasts. We are territorial, aggressive, and murderous. To our species and every other, this is why we wage war, this is the foundation of mass murder, serial killings, genocide, and our instinctive cruelty. We are killers. Listen to me, Louis. Dart further suggested that we did not evolve intelligence and then turn to killing, we evolved intelligence because we turned to killing. At some point, our ancestors branched off from their non-aggressive cousins. These early hominids became predatory probably because of the scarcity of food and probably by imitating other predators as primitives will do. We learned to stand erect to hunt, to give chase to our prey. Hands free to grip and tear, but lacking teeth or claws, we developed weapons. Crude imitations from bone, rock, wood. Ah, now the use of weapons entails great coordination, thus our nervous systems were challenged and our brains enlarged. The development of hunting tactics enlarged our brains still further. We are men today, Louis, because our ancestors were killers. As Robert Ardrey said in African Genesis, man had not fathered the weapon, the weapon fathered man.”
Earl said the “Killer Ape” theory was controversial as hell. Many anthropologists dismissed it and probably because it pretty much swept their conservative, bloodless little theories into the wastebasket where they belonged. But there was no need to doubt it now. Because out there, in the streets, the killer apes were running wild.
“The devil, as it were, has risen up from our chromosomes, Louis. Like certain diseases, cancers that are hereditary in nature, the genetic impulse to regress is irresistible. Fighting against it will be like fighting against the color of your eyes. It’s preset, preprogrammed, and absolutely immutable.”
Louis sighed. “But why did Macy regress and come out of it again? Why did you? Why haven’t I gone native yet?”
“Who can say, Louis? The gene may have been bred out of your family line at some point. There may be thousands like you or only a handful. As to me and the girl…I fear that the reassertion of reason is only temporary. A remission of sorts, if you will.”
