The Neolithic Revolution

I’m not sure that any of us can underestimate the impact of the Neolithic way of life. It has been the single largest step in social evolution since the inception of language. The industrial revolution, followed by the computing advances which heralded the onslaught of the information age have not even the slightest implications on human beings as a whole when compared to the radical shift in thinking which fascilitated the transition from hunter / gatherer to farmer.

In the ancient world the threat of a salted earth was one of the most feared consequences of war. To this day the practice still sends a chill down the spine of those who realize the true meaning of the term. Agriculture and civilization as we know it are so inextricably linked that even in our modern era of “magical” food availability we take pause at the icons of doom like plagues of locusts and burning timber land. These symbols of our ultimate damnation, etched into the inchoate proto-mind of all unborn children as an inherited memory, find such deep meaning to us that we are typically at a loss to describe the feelings they conjure.

Some time around 10,000 BC in an area of the world known biblically as Jericho a group of people began cultivating wild cereal grains for harvest. This group, known as the Natufians, were inspired to settle the region due to a radical climate cooling event called the Younger Dryas. The cooling of the immediate environment reduced the capacity of the land to support human life. This forced the people of the Jericho region to band together and form population centers with dependable food supplies. As with most things, necessity was the mother of invention. With their new understanding of the reproductive cycle of edible grains the Natufian populations were able to stabilize their food stores. This concept spread like wildfire.

With cooperative sharing of resources came the need for more permanent housing, systems of law, and perhaps most importantly the paradigm shift between seeing other humans as threats and seeing them as welcome help.

We still struggle hard against the wired primitive responses of our ancestors; but should we? Conflict between those who are different from us is a keystone of the human experience and perhaps one of the only urges which has allowed us to flourish. Perhaps it is the necessary evil of men that allows us to live in relative peace. It is this idea upon which the cold war was based… mutually assured destruction. Are there truly any better means of deterring violent interaction beyond the threat of a mutual obliteration. It is this struggle that urges us to develop notions like “good” and “evil”. It is this same struggle that drives us forward toward the uncertainty which exploration brings.

This balance, this delicate dance of human perceptions, can never yield lest we cease to be what we are. The human animal, hunter, nester, master its domain, is a living embodiment of speculation and the Neolithic experiment has been one of our grandest. Fighting our very nature yet embracing the alien has built for us a labyrinthine of shifting morality. Without something as simple as the agrarian manifest our fear would’ve long removed us from the harsh natural world. By the same turn we can never truly be free of the shackles of war or else we welcome destruction at the hands of the unknown. The world is good at giving us the unknown when we least expect it.

“Nature must not win the game, but she cannot lose. And whenever the conscious mind clings to hard and fast concepts and gets caught in its own rules and regulations – as is unavoidable and of the essence of civilized consciousness – nature pops up with her inescapable demands.”  -Dr. Carl Jung

ADHD and Evolution

In the past I’ve talked with my friend James about ADHD. He’s taught autistic children for several years now and is privy to some information on topics like this. The focus of my conversations has usually centered around my theory that ADHD should be embraced as an evolutionary step forward instead of a disorder to be treated. In the past I’ve put forward that an ADHD mind is capable of multi-tasking and information processing more efficiently than a “regular” mind.

At Dragon*Con I was lucky enough to be surrounded by a few great thinkers including C. Kevin Barrett, professor of anthropology at Ohio State university. He was booked on a panel regarding evolution and by pure luck we happened to be drinking in the green together. The good Mr. Barrett confirmed that there may be something to my theory, although he’d never seen anything published on the subject. He did confirm to me that other countries (speaking from a United States perspective) don’t categorize ADHD as a disorder; although my own research yielded statements from the CDC claiming a recent rise of anti-ADHD drug use in many parts of the developed world. He went on the explain that he feels we (as a society) need to take a closer look at the kinds of ideas I was promoting.

The common beliefs held by the majority of the psychological research community can be summed up in papers like The Evolution of ADHD: A Disorder of Communication, published in 2000. This, however, doesn’t jive with the work of Harpending and Cochran at the University of Utah. In 2005 they published on how natural selection in the modern era has forced genetic changes in various ethnic groups. From Hue Hueteotl’s blog:

“The new study comes from two of the same University of Utah scientists — Harpending and Cochran — who created a stir in 2005 when they published a study arguing that above-average intelligence in Ashkenazi Jews — those of northern European heritage — resulted from natural selection in medieval Europe, where they were pressured into jobs as financiers, traders, managers and tax collectors. Those who were smarter succeeded, grew wealthy and had bigger families to pass on their genes. Yet that intelligence also is linked to genetic diseases such as Tay-Sachs and Gaucher in Jews.”

This would account for the amount of ADHD in recent years. I truly believe that the proliferation of television, video games, wireless devices and personal computing has forced a rapid genetic change in the populations of the developed world. The model could’ve started in the 1950′s with the baby boomers and slowly mushroomed within the middle socio-economic classes.  From nearly a decade ago the statistics concerning ADHD economic divisions focused on this being a disorder of the lower economic classes, (See The Harvard Mahoney Neuroscience Institute Letter Winter, 1996) but more recently Dr. Ronald Kessler of Havard Medical School referred to it as, “a boutique diagnosis for middle-class people.”

This suggests to me that there is much more at work here than a neurological disorder. This disorder appears to bridging economic and racial boundaries at an advancing and consistent rate, something that is uncommon for psychological disorders. This lends some additional credibility to the theory of ADHD being a genetic adaptation to environmental stimulation.

However, at BorntoExplore.com the idea that ADD is an evolutionary throw-back is an equally compelling scenario. They suggest that ADHD / ADD is a hard-wired hunting / gathering adaptation used in primitive man to locate prey and avoid obstacles.

Perhaps there is something to be said for a full circle approach to this. Maybe the ADHD genes were more active in ancient populations and are re-asserting themselves as a response to our information-saturated world. The analog could be that a screwdriver can be used as a knife, a a building tool or a make-shift hammer. Maybe nature is digging into her existing toolbox to try to find something that can be adapted to the challenges of a wired society? It certainly might make more sense than inventing a new adaption.
