Some of the least complex toys are the most powerful.  In the 1950s, my parents seemed amused that Slinkys and Hula Hoops had captured my sisters’ and my attention.  These toys were so simple.  Nevertheless, they were compelling.  Some of the simplest metaphors or processes can suggest or reproduce seemingly complex relationships.

Seeking to understand human evolution by focusing on individual adaptability to circumstance offers some unique and useful perspectives.  Exploring human evolution by examining humans in society can in ways simplify the play of transformation.  Raising the scale, shifting to society from individual, can simplify our understanding of the process.

Marian Annett’s explorations of the brain changes that compelled a shift to speech revealed a “balanced polymorphism,” or seamless arch of human features from those humans with little speech facility to others cerebrally lateralized so intensely for speech that they are handicapped in communication.  Those in the middle, she suggested, had a heterozygote advantage by retaining some of the useful pre-speech strengths in combination with speech proclivities.  Speech facility demands that the right hemisphere be pruned of some of its potential growth and subtlety in combination with a brain bridge reduced in size.  Odd that a reduction in hemispheric …

No device exists that measures consciousness.  There is no consciousness Geiger counter that provides the opportunity to visit different places and measure their degree of connectivity.  There is no helmet you can strap onto chimpanzees and humans that will measure how aware an individual is of his or her particular situation.

Ken Wilber hypothesizes that meditation engaged in over 20 years provides a leap of two units (on a scale of approximately 7 units) from where you began on the climb to enlightenment.  Wilber suggests where we begin depends on life circumstances, personal history, social context, historical situation and personal choice.  A number of different behaviors or experiences suggest one’s location on the ladder.  For example, Wilber observed that fear dramatically diminishes the longer one engages in the consciousness climb.

Personally, I’m more interested in the nature of the differences among individuals subscribing to different social structures and the hormonal associations with those social structure proclivities.  Measuring how enlightened someone is feels unnecessarily hierarchical and sort of anti-Zen.  Noting the difference between humans 200,000 years ago–hypothetically random-handed humans with no shift in cerebral functioning enhancing speech–and humans today, who are exhibiting varying degrees of random-handedness, sounds interesting and possibly useful.  …

Noting that our testosterone levels are determined in our mother’s womb by our mother’s testosterone levels, girls reflecting the mother’s threshold, boys polarizing to the opposite, I’ve hypothesized that estrogen might follow the same dynamic.  The results are intriguing.

A high-testosterone mother gives birth to a high-testosterone daughter and low-testosterone sons.  This is also a prototypical matrifocal social structure with high-testosterone women mating with low-testosterone males.  Conversely, low-testosterone moms birth low-testosterone daughters and high-testosterone sons, the patrifocal prototype.

I hypothesize the same dynamic in estrogen engenders not a social structure proclivity but a sexual selection tendency.  A high-estrogen mother gives birth to a high-estrogen daughter and low-testosterone sons.  Low-estrogen mothers create low-estrogen daughters and high-estrogen sons.  When the female has high estrogen she is very discriminating in the male that she chooses to mate with.  When the male has high estrogen he is very choosy, seeking childlike features in the woman he would have as a wife.

Four kinds of societies emerge, with eight types of individuals mating with their complementary opposite.  (F=female, M=male, T=high testosterone, t=low testosterone, E=high estrogen, e=low estrogen)

I am a web developer by profession, trained in fine arts.  My specialty in web design is creating websites and website features that enhance communication, eliminate barriers to cooperation, empowering individuals to accomplish social and political-change goals.  I work with more than 1,000 organizations across the United States, teaching leaders of organizations how to use these new tools to break down barriers to change.

I also run a firm that serves over 400 businesses by building, maintaining and marketing their websites.  Trained in the art of online organizing by Moveon, I advanced to the position of volunteer national coordinator.  There I learned firsthand how to combine a focused, goal-based business frame of reference with a deep desire to encourage societal transformation.

My background is fine arts.  As an artist, I specialize in brush and ink.  The way that I have exercised my art also involves the breaking down of barriers.  First, I seek to let go of conscious control of subject and process and allow my unconscious to determine the path and content of my productions.  Second, the content itself, when successful, creates bridges between separated concepts, connections between not-obviously-related ideas.

I am not suggesting this qualifies me to be …

The biological concept of a balanced polymorphism applies to society exhibiting a seamless gradation of individual types with an emphasis on heterozygote advantage.  Neuropsychologist Marian Annett reframed being left-handed as being random-handed and then observed a seamless arc of handedness from extreme left-handers at one end to the extreme right-handed at the other.  The left-handed had no gene for being left-handed.  They had no gene for being handed at all.  Annett hypothesized that over the course of our evolution, the gene for right-handedness emerged, which resulted in facility for speech.  Still, Annett hypothesized that the older genotype, the random-handed, retained importance.

Most people in a society are neither extreme left nor right.  Many people display a heterozygote advantage by exhibiting features of both random-handed and right-handed dispositions.  Still, as a society transforms, it drifts in the directions staked out at the extremes.  It is often those members of a society living at the poles that manifest the diseases, disorders and conditions that suggest the difficulties of living at the boundaries.  In addition, many of the most talented in a society spring from the left, the random-handed pole, the older genotype.  There are advantages to having a brain not wired for …

Consider that human evolution unfolds in a fashion not dissimilar to the way an accordion player produces melody and harmony while inflating and deflating his instrument over time.  The accordion player may observe his audience and modify cadence or change the tune depending on whether folks are dancing, how fast they’re dancing or whether they are paying attention at all.  The instrumentalist’s environment informs the tune he plays and how he plays it.

Human communities are composed of many types of folks.  Not just the individuals in communities are molded by evolutionary processes, but the communities themselves behave like selected targets with those communities that exhibit a variety of useful features that encourage a thriving population surviving and procreating.  This has been called a balanced polymorphism.  A wide variety of human types can contribute to a healthy, balanced polymorphism and a healthy community.

For example, in contemporary society, we observe the artists, caregivers and athletes performing and serving while exhibiting strengths peculiar to their particular neurology, psychology and physical proclivities.  Politicians and business people do what they do best, stoking the economy and growing opportunities.  Aesthetics and usefulness combine to create a satisfying social experience and a balanced society.

I’ve talked about the effect of sunlight on the pineal gland changing testosterone levels of immigrants from equatorial regions. Equatorial people with established, normal, daily 30% fluctuations in testosterone move to northern climates and experience fluctuations that last for months, thus compelling radical changes in a mother’s uterine testosterone levels. Unusually high or low mother’s uterine testosterone levels can cause unusually high or low testosterone levels in her children, translating into exaggerated maturational delay and acceleration (depending on the season of conception) that can contribute to autism.

In previous pieces, I’ve noted these effects on Jewish and American Black populations, with a skewing of populations toward the extremes of maturational delay and acceleration evidenced by a number of diseases and disorders characterized by these hormonal extremes. I would predict that both these populations would evidence higher percentages of autism and left-handedness, perhaps higher in places like Milwaukee and Minnesota than Houston and Miami. In just the way the Somalis in Minneapolis and St. Paul are exhibiting higher rates of autism, I would suggest that this Somali population would exhibit higher rates of left-handedness.

Another population influenced by these processes are the Latino immigrants from South and Central America. Studies could …

Two biological processes impact the American Black population, resulting in increased learning disabilities, specific medical maladies and challenges not familiar to most other ethnicities and most whites of European origins. In addition to the challenges of these biological circumstances, as a result of these processes, the American Black population is also blessed with gifts that provide recognition and respect, and now the presidency.

There are three primary genetic pools in Africa. One genetic source is believed to have resulted in literally all other humans that have distributed themselves about the world since the diaspora of 50,000–80,000 years ago. The other two are far smaller, located in central and east/central Africa. All three are relatively ancient compared to the many other ethnicities across the planet.

Darwin observed, while breeding pigeons, that when two widely divergent threads or strains mate or blend, having had no genetic contact for a prolonged period of time, the progeny often reveals traits of the last common ancestor. For example, Chinese pigeons were bred in isolation from European pigeons for more than 2,000 years. When cross-bred, they revealed features of the Roc pigeon, ancestor to both derivations.

Breeders would sometimes observe a surge of archaic features that …

A superb 25-year study in the UK by Marian Annett ending in the 1990s seemed to prove that in that part of the UK, left-handedness was not increasing over time. It’s been a difficult issue to parse out, what with left-handedness being repressed before WW II. When conventional wisdom declared that forcing children to switch hands would encourage stuttering, schools withdrew from demanding all children use the right hand. A result has been that though it looks like the number of left-handers has been increasing over the decades, it is obvious that institutions stopping the repression of left-handers has skewed the numbers.

A similar effect is seen in Asia. Society has strongly encouraged that the left hand not be used. The rates of left-handedness in many parts of Asia are 2% and lower. It’s difficult to determine the true handedness percentages.

The same effect comes into play with autism. Though it seems there have been dramatic rises in autism over the last twenty years, many believe we just have more refined evaluation protocols with more attention being placed upon those individuals exhibiting unconventional behaviors.

The thesis presented in this work makes several predictions regarding handedness and autism, two issues that …

In the neuropsychological literature, there is periodic discussion on why left-handed women, women generally, as a group that are less often left-handed than men, birth more left-handed children than left-handed men.

Long story short, the three-discipline, central thesis of this website states that a mother’s uterine testosterone levels determine her children’s testosterone levels and their maturation rates.  The sexes tend to emerge as complementary opposites.  A high-testosterone (T) woman birthing high T girls and low-testosterone (t) boys.  A low t mother births high T boys and low t girls.  A person’s testosterone levels inform that person’s maturation rate.

An individual’s testosterone levels also inform their social structure proclivity.  High T females mate with low t males in our hypothetical matrifocal society.  (We hypothesize estrogen is a vital matching variable, but because we are suggesting that estrogen plays little part in the establishment of maturation rates and proclivity toward left-handedness, I’m leaving estrogen out of this part of this discussion.) When a mother’s uterine testosterone levels radically change, or a high T mother experiences environmental prods further elevating T levels, her progeny can reflect that elevation both in their testosterone levels and in their maturation rates.

What then happens is a …

Two things have contributed to a rather extreme crash in self confidence.

A reader commented on one of the postings, asking for the text that notes that six weeks before birth maturation rates are set by mother’s testosterone level.  Finding the link to the citation on my research site,, the link did not provide the page number in the text Cerebral Lateralization, nor was there an excerpt as there usually is.  This was uncharacteristically sloppy, particularly for such an important citation.  So, I reread Cerebral Lateralization, finishing it a couple days ago.  I find the source of the information.

I then conducted searches of perhaps a hundred pages of my notes, excerpts from text.  Then I scanned Google for the evidence.  I can find it nowhere. I remember reading it and taking notes.

Though there are a number of passages noting the relationship between a mother’s testosterone levels and the maturation rates of her children, I can find nowhere the allusion to six weeks before birth being the deciding moment.  I’ve noted this dozens of times in my work.  I can find no evidence of where I read this.

I am appalled.

In addition, we plugged in Google’s Analytics …

Insight Into Process

A peculiarity of this blog format presentation of evolutionary theory is the exhibition of the process I go through as the theory forms.  Not only do I leave a trail of the mental processes leading to an insight or conclusion (often the insight comes as I write, with my having no ideas where a particular day’s entry is leading), but I describe events in my personal life along with feelings that inform my life and this work.

I’m starting to believe this is not accidental.  I mean not accidental in the sense that my unconscious, the author of this work, seeks a deeper communication than just the thesis of this work.  The way that science is conducted now offers proofs, peer-reviewed commons (journals) and difficult-to-achieve authorizations to conduct research (advanced degrees).  What I have is process.  I seek to show the sources that a theory springs from, offering insight as to the process that leads to theory.

This presupposes that what I’m creating offers some usefulness.  Otherwise this is a unique adventure having to do solely with art, not science.

In the event that the principles that have emerged in this website do serve, then the nonscientific aspects of this …

Last night was one of those nights when I could not easily fall asleep.  I’m conducting an experiment.  I’m feeling compelled to sleep on my back to see if over six months my left-side, 12-13 mm quasi-fusiform carotid artery cerebral aneurysm diminishes in size.  I’ve slept on my right side my whole life.  It’s not likely, based on what the surgeons have suggested, that sleeping on my back can have an effect.  Still, I feel like there is something I can do to make a difference.  The night I came to this conclusion was the night that the four-pole thesis began to form.

So I sleep light instead of my customary deep.  Mortality feels not particularly far away.  Often my mind starts wrestling with the principles discussed in this blog.  On nights like last night, I move the concepts around a 4-D space, looking for new relationships.  A couple things came to mind last night.

In the four-pole hypothesis….

Why are specific diseases, disorders and conditions emerging with specific populations at this specific time?  Can the principles that we have recently focused on involving estrogen and social structure lead to clearer answers than those we’ve received until now?

The foundation of this theory I’m calling my “Theory of Waves,” formerly called Shift Theory, is built from social theorist Riane Eisler’s focus on matristic society, Marxist anthropologist Chris Knight’s human evolution theory based on female choice, evolutionary psychologist Geoffrey Miller’s theorizing on sexual selection, Charles Darwin’s work on sexual selection (and Lamarckian selection), Stephen J.  Gould’s addressing heterochronic theory and neoteny, Norman Geschwind’s Cerebral Lateralization conjectures and Marian Annett’s research on random-handedness.  Simon Baron-Cohen’s recent personal encouragement that this theory is significant has provided me the confidence to begin contacting researchers and academics as I seek support and criticism of the Theory of Waves.  I am an amateur theorist with no institutional support.  The concepts herein have not been exposed to peer review.  I am not a scientist.

I view this creation as a work of art.  I pay attention to what seems interesting.  I let myself be guided by what draws me.  I am constantly sifting through patterns, feeling …

I’m starting to muddle through the implications of the four-pole hypothesis of four prototype pairings, with eight prototype human beings, four in each sex. (Proceed to the essays “Estrogen Ascendant” and “Estrogen Play” for more background on the concepts addressed in this essay.)

I’ve noted a couple times over the months that there is a five-step evolution continuum that begins with natural selection and then moves to step two where sexual selection focuses on a specific pattern when one (usually the female) chooses a mate.  Step three begins with human sexual selection, where adept practitioners of novel pattern creation (dance, song and later language) are selected as partners (usually by females with sensitivity to these subtle differences).  The fourth step is taken when novelty itself becomes desirable outside the partner-selection process, and society is compelled to embrace in its productions the infinite nuances of the new and less familiar.  In the fifth stage, awareness of evolution’s stages, attended by an awareness of the awareness that accompanies evolution, provides an identification with the five-stage creation continuum.

2)    sexual selection (selecting for pattern when seeking a mate)

For the last two nights while I’ve been dreaming, my mind has been wrestling with an integration of testosterone and estrogen in the model that’s come together the last three weeks. Dreams, metaphors and thoughts combine to synthesize the variables and data. This morning I awoke aware that there’s been a piece that is seeking understanding.

Marian Annett has pioneered new understandings of handedness, generating a host of clues as to how humans evolved and order themselves in society. Annett hypothesizes that one might be random-handed or right-handed, with a continuum of tendencies revealing that it’s not as easy as being one or the other. With our tentative model of evolution and society formation, repeating an earlier posting…..

The result will be natural …

“Musical composers, instrumentalists, and painters were compared with nonmusicians from a student and from a nonstudent population on testosterone levels in saliva. This steroid served as a marker for physiological androgyny. The ANOVA showed a significant group by sex interaction. Male composers attained significantly lower mean testosterone values than male instrumentalists and male nonmusicians; female composers had significantly higher mean testosterone values than female instrumentalists and female nonmusicians. Painters of both sexes did not differ significantly from controls. Spatial ability was assessed in the five groups. Significant differences on spatial test performance were not reflected in differences on salivary testosterone. Our results showed that musical composers of both sexes were physiologically highly androgynous. Creative musical behavior was associated with testosterone levels that minimized sex differences.” (Hassler M (1991) Testosterone and artistic talents. Int J Neurosci 56 (1-4): 25)

Surveying papers that either directly relate to my studies or tangentially connect to what I play with, I come across paragraphs that jump out as supporting my ideas or that flail me with a totally dissonant perspective. I track both, though I store the latter with less enthusiasm. Some of the contradicting studies show in their study techniques a rather lax attention …

As an artist and a theorist, I hope that the ideas I observe emerge with a display of both beauty and usefulness.  The artist seeks beauty.  The theorist seeks usefulness.  This two-week journey out onto a theorizing limb makes estrogen (along with testosterone) central to evolution, using a dynamic evidently already established (according to my theory) by testosterone.  It’s a guess.  It’s a guess based upon a solution that resolves anomalies but a guess not even close to being proven.

The artists plays.  I’ll continue to play with these concepts and get a feel for whether these ideas are useful.

Almost six weeks ago, Simon Baron-Cohen responded to an email that I had sent to him.  Professor Baron-Cohen noted in his response that this website’s ideas concerning autism were “fascinating”, “deep and important.”  Simon Baron-Cohen is perhaps the world’s foremost authority on autism etiology.  This was an unexpected and deeply rewarding response.  Receiving permission to quote him, I began emailing autism researchers.  Over the last month, I’ve contacted over 200 autism experts and academics specializing in related conditions or specialties.

I’m receiving email responses by researchers, academics and professionals.  The quote by Simon Baron-Cohen has been integral to folks taking …

The result will be natural mated pairings resulting in across-sex matchings of testosterone and estrogen that will be complementary opposites. We are hypothesizing that there will be exceptions, but they will not be the convention in that society.

Geschwind and Galaburda in their 1987 Cerebral Lateralization noted a number of patterns across studies that seemed to support a relationship between lateralization, handedness and a number of diseases and conditions. Follow-up studies often led to results that were ambiguous. Still, the work of Simon Baron-Cohen and his colleagues have come to conclusions that have suggested connections that Geschwind and Galaburda alluded to. Specifically, mother’s testosterone levels inform conditions characterized by male maturational delay. Marian Annett continues to pioneer an understanding of a paradigm characterized by random-handedness balanced by conventional handedness that she calls Right Shift Theory.

In other essays on this website (i.e., Evolutionary Theory, Neuropsychology and Autism), I have described the integral connection between heterochronic theory and the neuropsychological patterns observed by Geschwind and Galaburda, developed by Annett and Baron-Cohen. Heterochronic theory describes how species evolve when influenced by changes in the rate of timing of maturation and development. Neoteny is one of six heterochronic patterns, the prolongation or lifting of infant or embryonic features from ancient ancestors into the features of adult descendants, resulting in the slowing down of maturation, with features of early ontogeny appearing later in ontogeny over generations. One does not just mature …

The Father

January 13, 2009 | Leave a Comment

Category: Ontogeny

Consider that the father’s sperm, each ejaculation, represents the somatic conditions in the male’s body at the time of sperm creation.  Consider that each sperm carries with it information that tells the child how high or how low the child’s testosterone or estrogen levels will be based on the father’s levels of testosterone and estrogen.

I tried playing with this conjecture as an assumption ten years ago when the theory’s pieces first came together.  I’ve let it languish because I’ve noted no studies that have considered this possibility.  There is no supporting evidence.  It would be easy enough, with funding, to set up long-term studies.  The problem is that we’re discussing Lamarckian principles.  Sociobiology or evolutionary psychology may be on the wane but mentioning Lamarck in a proposal will still likely draw derision.

Over the last few days we’ve hypothesized an estrogen dynamic similar to what we’ve observed with testosterone.  At six weeks before birth, the mother’s testosterone levels determine the testosterone levels and maturation speed of her progeny.  Estimating that estrogen levels may be determined in a similar fashion, with caregiving and aesthetic-choice tendencies influenced by those levels, we’ve unimpacted several implications having to do with human evolution, societal …

I started writing these essays on January 1, 2008.  I had perhaps twenty pieces that I’d written over a period of years.  I did not know if I had enough to say to write each day.  I didn’t know if there were enough things that would hold my interest.  As winter warmed, I was able to write each day, and I concluded that finding things to hold my interest was not a problem.  There was a delay putting up the site as my firm’s staff member that specialized in WordPress had to get other projects put to bed.  Finally, on April 1, the website posted.  I began with the essay I wrote on the first of January.

The 200th essay is posting tomorrow, except that today is October 9, 2008.  By the time you read this, it will be mid-January, and this one I’m writing now will be close to the 300th essay posted. [As it happened, this is essay 300.]  So, I am always about 100 days ahead of what’s being posted.  Not incidentally, this allows me the time to send them all to an editor to be reviewed.

This delay makes for a number of unique effects.

Two interlocking models or paradigms describe how humans evolve.

In the first explanatory paradigm we are now looking at a modification of our model.  We now have two complementing dynamics.

Mother’s testosterone levels > progeny maturation rate > social structure proclivity > evolutionary trajectory.

Mother’s estrogen levels > progeny ability to exercise aesthetic discrimination and caring behavior > social structure proclivity > evolutionary trajectory.

I hypothesize two feedback loops.  Mother’s testosterone level > progeny maturation rate > social structure proclivity > mother’s testosterone level.  Mother’s estrogen level > progeny ability to exercise aesthetic discrimination and caring behavior > social structure proclivity > Mother’s estrogen level.  The environment can intervene at all three levels of both loops by influencing maturation rates and timing (via testosterone) or by influencing mate selection criteria (via estrogen), thus modifying the trajectory of human evolution.

The second explanatory paradigm involves a five-step continuum beginning with natural selection and then moving to sexual selection, with animals focusing on particular patterns when they choose a mate.  Step three begins with a bridging over to human sexual selection, where adept practitioners of novel pattern creation are selected as procreation partners by mates with sensitivity to these nuances.  This is …
