Hypothesizing that humans evolved in a meandering fashion oscillating between high testosterone (T) females and low T males in matrifocal societies and high T males and low T females in patrifocal societies we might estimate that the skeletons of our ancestors would reveal those tendencies with gracile (matrifocal) vs. robust (patrifocal) remains.

I’ve referred to the feedback loop. Mother’s testosterone level > maturation speed > social structure > mother’s testosterone level. The environment intervenes at all three levels of the loop, influencing maturation rates and timing, modifying the trajectory of human evolution, creating a pendulum that swings back and forth between the two social structure paradigms.

Females picking males most adept at dance select those males with the most neotenous characteristics. Particularly important are those males with big, neotenous brains. Just as a predator needs more synapses than its prey, a dancer that needs to capture a mate has no ceiling in the synapses required to manifest the most astonishing moves. Brains grew bigger exponentially to achieve mating opportunities while males were competing with other high-stepping, big-brained fellows.

Big brain growth was not a seamless, single line of exponential increase. Different ancestral species, such as Homo erectus, exhibited different speeds of cerebral increase in different regions of the world. Rates varied as matrifocal and patrifocal paradigms competed. Matrifocal trends encouraged bigger brains as the result of female aesthetic choices, which resulted in more neotenous, big-brained males. Patrifocal tendencies resulted in bigger brawn and little brain growth as intramale competition determined progeny characteristics. Rates of increase varied with geographic location, social structure, and perhaps other variables, such as more or less hospitable environments, the proximity of other humans, technological innovations and the influence of altered states.

A premise of this model is that we can travel backward in time by becoming more maturational delayed (if we are males) and more maturational accelerated (if we are female), propelled by the mother’s testosterone levels at six weeks before birth. Moving backward, we move in a matrifocal direction. The autistics among us have traveled back to when language was bridging from gesture to speech, back before we departed Africa.

Consider that maybe 50,000 years ago a male ancestor, maturational delayed, traveled back in maturational time to a male ancestor that was maturational accelerated. Go far enough back into matrifocal-male maturational delay and backwards in time becomes a period when there were maturational-accelerated, patrifocal males with high T, not low T. Remember, we did not evolve in a straight line.

Maturational-delayed males may be propelled so far back in time that they exhibit maturational acceleration. For females, the reverse would be true. A maturational-delayed male might also get boomeranged or propelled further back in evolutionary time by arriving first in the position of an ancestor that was himself propelled back in time, piggybacking onto that ancestor’s acceleration or delay.

Stored in our genes is memory of ancestors’ hormonal states. Our half-billion-year ontogeny is the re-enactment of that journey. How we walk that path is determined by our mother’s testosterone level, six weeks before our birth.

I hypothesize that Tourette’s syndrome is a male or female propelled into the past, beyond where the autistic originates in time, further back to where sometimes both patrifocal and matrifocal social structures coexist, depending where you are in geography, perhaps back to where patrifocal preceded a matrifocal surge.

If Tourette’s exhibits the same dynamic as autism, an exhibition of an ancestral hormonal constellation, then perhaps medical conditions with hormonal markers reveal etiologies characterized by the physiological and neurological emergence of the past.

There is the obsession with rhythm and pattern of the autistic. There are the stylized grooming rituals exhibited by those with Tourette’s.

Observe those unique individuals with autism or Tourette’s and consider what kind of society they’d call home.

    I’d like your thoughts about these two hypotheses of mine: micro-perfectionism in those suffering from TS (and perhaps autism), and CUBS (“Chronically Under-informed Bio-clock Syndrome”)…

    My heart goes out to all who suffer directly or indirectly from TS, autism, OCD, etc.

    Perhaps what follows may help some of them… (and perhaps you can help us help them?)

    Many years ago I read an article in the New Yorker Magazine by Oliver Sachs about something seemingly impossible. He described a very highly regarded surgeon who has TS,Coprolalia. This was considered unexpected enough to write about because obviously a great surgeon with TS, Coprolalia seems like an oxymoron.

    There was one part of the article that caught my eye: the surgeon was a perfectionist in everything he did. A very good thing when doing surgery. And perhaps a clue to something about TS that might be being overlooked and/or under appreciated by those too close to TS. I.e., what if all those inappropriate verbal outbursts and abrupt movements were due to a scale & timing issue?

    That is, what if those afflicted with TS and Coprolalia were reacting to very tiny to us — yet terrible to them — mistakes that they were perceiving at a micro-level under our radar/scale of conventional perceptions? And what if their time-frames for making those judgments were also of micro-duration? Perhaps, very silly possibilities, and yet ones that I am inclined to believe fit the observable data.

    Which, as TS and Coprolalia (and autism…) are known to be associated with malfunctioning biological clocks, now also gets me to something freely available on the Web: my recently patented Synclecron, found via http://GreenTyme.org, now being studied in the Azheimer’s and Dementia Units of two Assisted Living Facilities. As everything in life is time and timing, and as bad timing is such a fundamental issue with Tourette’s Syndrome, (and as sufferers of autism seem to live in their own world and time), I look forward to hearing from you about my micro-perfectionist hypothesis — and also our chronically under-informed bio-clock one.

    Needless to say, everyone interested in studying how the Synclecron might help themselves and/or those they love is welcome to use it, and make any positive results known to others in the TS community, and other communities — and hopefully to us as well.

    Hi Yale,

    I don’t have enough experience to get a feeling on how much the micro-perfectionist hypothesis might fit. I lived with a friend that had rather exagerated Tourette’s for a few months. It felt great ape to me. His intelligence was astonishing. At the same time he was constantly accompanied by compulsions. Many of the compulsions were triggered by the environment. I wonder how much of Tourette’s is social in nature.
