In 1993, ADHD advocate Thom Hartmann wrote that individuals recognized with ADHD are ”hunters in a farmer’s world.” On this video, I proceed his prepare of thought by specializing in how ADHD could finest be represented as a genetic adaptation to situations throughout prehistoric instances. The video describes Darwin’s concept of pure choice and examines how the traits of the hunter (all the time on the transfer, responds rapidly to stimuli, attends to a number of issues at one time) now manifest because the signs of ADHD (hyperactivity, impulsivity, and distractability). I take a look at the DRD4 dopamine receptor gene and the way researchers have sought to trace down this ”hunter’s gene” within the genomes of individuals within the Paleolithic Age, thus offering some help for Hartmann’s declare. Lastly, I describe careers for individuals recognized with ADHD the place the talents of the hunter may be included into up to date jobs (e.g. firefighter, emergency room doctor, forest ranger and so forth.) and thus assist these people to search out satisfaction of their lives and success on this planet. Please word {that a} full transcript of the video is obtainable beneath.

Hello, I’m Dr. Thomas Armstrong. That is half 8 of my 12-part video collection on The Fable of the ADHD Baby. This video is entitled ‘’ADHD as an Evolutionary Benefit’’
Let me preface this presentation by saying that I DO imagine that ADHD signs exist. However I imagine after 50 years of finding out this challenge, that the speculation that there’s a particular medical dysfunction referred to as ADHD inflicting these signs is improper and that there are various different factors of view that may account for these signs. Partially 1 of this video collection, I clarify why I name ADHD a fantasy. On this video, I take a look at how what’s considered as ADHD could as an alternative be an evolutionary benefit.
In 1859, the British naturalist Charles Darwin wrote The Origin of Species, one of the vital influential books written within the trendy period. In it he proposed the idea of pure choice because the underlying precept of evolution. In accordance with Darwin, organisms which have traits adaptive to their fast atmosphere are inclined to prosper and these traits are then handed alongside to subsequent generations. Then again, organisms which have traits that don’t adapt nicely to their atmosphere die off due to their failure to adapt and their traits are misplaced to subsequent generations. Thus, some traits are preserved over time and different traits are misplaced, all due to the best way they both did or didn’t adapt to an organism’s fast atmosphere. This helps clarify many of the traits that we see in organisms from micro organism to human beings.
One of many clues that gave Darwin inspiration for his concept was his remark of finches on the Galapagos Islands, 600 miles off the coast of Ecuador in South America. He seen the variations of their beaks from these he noticed on the mainland of South America and got here to the conclusion that the variations between their beaks had one thing to do with their capacity to search out and devour meals. These finches with thicker beaks, for instance, had developed traits that have been in a position to crack open seeds, whereas these with spear-like beaks have been higher in a position to penetrate, kill, and devour bugs. Every chicken sort had developed its personal solution to finest adapt to a seed-rich or an insect-rich atmosphere.
Now let’s shift our focus to 1993. In that yr, American radio character, creator, former psychotherapist, businessman, and progressive political commentator Thom Hartmann wrote a e-book referred to as Consideration Deficit Dysfunction: A Totally different Notion [slide 18] Within the e-book, Hartmann prompt that individuals with ADHD have been the ‘’hunters’’ of our tradition, descended from the hunters of the prehistoric period.
He asserted that so-called regular or neurotypical persons are the farmers of society, descended from individuals of the Neolithic age when agriculture emerged as the first sample of cultural improvement. Therefore his slogan ‘’Hunters in a Farmer’s World.’’ After I first came across Hartmann’s concept, I discovered his concept fascinating however considered it extra as a metaphor than an precise genetic phenomenon. Little did I think that there was extra to this concept than mere metaphor.
Right here [slide 8] we will see how ADHD appears associated to the hunter character. Hunters within the wild in prehistoric instances needed to be always on the transfer with a view to discover discover meals to deliver again to their households. In addition they needed to deal with predators, holding away from them, whether or not they be animals or hostile tribes.
The farmer then again, doesn’t transfer round quite a bit. He stays along with his crop. Places the seed into the bottom and waits. There must be quite a lot of capacity to delay gratification whereas ready for the plant to germinate, develop, after which produce fruit. Plenty of endurance is required.
Hartmann means that what we regard as a symptom of ADHD, that’s, hyperactivity, is a trait that was preserved from the period of the hunter in the course of the Paleolithic Age, as a result of it was an adaptive trait that allowed him to get meals and keep away from changing into meals, thus prospering and passing this traits onto future generations.
Equally, the hunter wants to concentrate to a number of issues on the identical time. A twig breaking that will imply {that a} predator is close to, the sound of drums within the distance might signify a tribe within the space, animal tracks on the bottom may counsel the presence of a possible meals supply. The hunter who would cease and stare for hours at an animal observe may nicely be wolfed up, thus not passing his ‘’endurance’’ genes on future generations.
The farmer then again, DOES deal with issues for lengthy durations of time, particularly after they relate to his elevating grain crops or tending to his herd of cows, sheep, oxen, or different animals.
The power to deploy consideration for brief bursts of time that the hunter makes use of as a bonus out within the forest or jungle, we now discuss with because the ‘’distractibility’’ of the so-called ADHD particular person. What was a bonus in prehistoric instances is now seen as a warning signal of ADHD.
Lastly, the hunter wants to reply rapidly to any enter he receives from the atmosphere. He hears the sound of a mountain lion and if he doesn’t react rapidly, by operating to security, or by advancing on the animal, then he’s toast. That’s the top of him. The hunter who’s ABLE to reply rapidly, has a transparent benefit, and this trait is probably going then to be preserved and handed all the way down to future generations.
The farmer then again, takes his time to file information – climate patterns, precipitation quantities, development of vegetation, and different data – to raised assist him in elevating crops or tending to his herds.
The power of the hunter to reply rapidly to enter from the atmosphere throughout prehistoric instances, which was a bonus at the moment, is now thought of a warning signal of ADHD. We name it impulsivity.
Partially 3 of this 12-part video, I talked in regards to the DRD4 gene [slide 17]. One explicit allele or variation of the DNA sequence of the gene (the place the sequence is repeated 7 instances). is said to, nicely, you may name it ‘’risk-taking’’ or ‘’novelty-seeking’’ and even ‘’reward-seeking’’ or ‘’sensation looking for.’’ This can be a ‘’hunter’s gene’’ preserved in evolution as a result of it conferred benefits in survival capacity. And it appears to be prevalent in individuals recognized with ADHD. So now now we have one thing particular to work with by way of substantiating Hartmann’s declare that individuals recognized as ADHD are descended from the hunters.
Now let’s take a look at a fast chronology. Hartmann’s e-book, initiating this concept, got here out in 1993.
In 1997, the primary scientific paper giving some credence to Hartmann’s outlook got here out within the Journal of the American Academy of Baby and Adolescent Psychiatry [slide 19]. It referred to ADHD as a dysfunction of adaptation.
In 2001 a research got here out [slide 20] within the prestigious Proceedings of the Nationwide Academy of Sciences, suggesting that this 7-repeat allele within the DRD4 gene originated as a uncommon mutational occasion that nonetheless elevated to excessive frequency in human populations by optimistic choice. So, the pure choice speculation of the ADHD gene appears to have some help right here.
In 2020, [slide 21] scientists checked out gene sequences in populations dwelling in prehistoric instances in comparison with trendy instances and located that the frequency of variants related to this hunter gene has steadily decreased since Paleolithic instances, which is sensible by way of humanity’s shift from a primarily looking tradition to an agricultural or farmer’s tradition.
Right here’s a timeline [slide 22] exhibiting the totally different ages of humanity over the previous 800,000 years. You see that many of the timeline is given over to the paleolithic period – the age of the hunter and gatherer. Thus, for more often than not human beings have existed, they have been hunters, not farmers. Agriculture is a comparatively current improvement extending again maybe 12,000 years, a fraction of human beings’ time on the planet.
We developed as human beings in environments that have been pure, usually unpredictable, and requiring the talents of the hunter to outlive.
It bears noting right here that we did NOT spend 800,000 years cultivating genetic sequences by pure choice that relate to environments like this one [slide 24]. We have been merely not genetically programmed to spend 5-6 hours a day within the typical classroom atmosphere. And but that’s what we anticipate of our kids and teenagers. Partially 4 of this 12-part collection on ADHD, I discover the best way faculties are structured and the way they’re mind hostile to college students recognized with ADHD, partially as a result of they want education that’s novel, thrilling, and fast-paced.
Some individuals may say, nicely, we don’t reside in a rainforest or jungle, we reside in a contemporary twenty first century tradition, and our children have to adapt to THIS atmosphere. The fact is that our up to date tradition consists of quite a lot of environments, a few of which children labeled ADHD have bother adapting to, like this one, and different environments that capitalize on sensation-seeking, risk-taking, or novelty-seeking traits. We should always use this data to assist design our lecture rooms for teenagers, after which steer these college students in the direction of careers the place to achieve success means utilizing these risk-taking, novelty-seeking traits.
Careers like firefighting, the place there’s quite a lot of motion, motion, and thrills and chills. The place an individual wants to concentrate to many issues on the identical time. The place one wants to reply rapidly to enter from the atmosphere.
Careers like mail supply that contain novelty and motion. These jobs exploit among the traits of the hunter transplanted into up to date life.
Careers like emergency-room doctor or EMT, once more the place situations within the ER are survival-based simply as they’re out within the wild for the prehistoric particular person.
Or jobs like being a roving journalist or TV reporter, that contain new assignments on a regular basis, being attentive to a number of cues and stimuli and staying on prime of all of it.
Or careers like forest ranger or nature photographer, that actually get one out within the wild and mimic situations of the prehistoric hunter. Understanding ADHD as an evolutionary adaptation isn’t simply restricted to finding out the lives of human beings 1000’s of years in the past. It may give us clues as to how one can assemble our lecture rooms, and the way individuals recognized with ADHD can efficiently adapt in right now’s advanced world.
