“To adopt Dawkins’ gene’s-eye view for a moment, we can see that it would make sense for a gene to take advantage of any developmental opportunity, without caring whether the influence originated inside its organism’s skin or outside it.  Viewing this widely ramified network of interactions in terms of extended phenotypes rather than of developmental systems, however, has several disadvantages.  First, if a gene’s phenotype may be part of another organism’s body, then any organism’s genotype would seem to be distributed as well.  Just what genes were part of that genotype, furthermore, would change with time, since different genes would ‘manipulate’ this particular body at different times.  Second, even if one retains a more mundane view of genotype roughly as that complement of genes enclosed within the skin, the organism in Dawkins’ account is not only something of an epiphenomenon to genetic wheelings and dealings (as it already seems in many sociobiological accounts), but a mosaic epiphenomenon to boot, created to run by its own genes and by the genes of multiple others.  The concept of the developmental system, on the other hand, incorporates the insight that a given phenotype is a product of quite a bit besides its own genes without doing away with the individual organism itself.  It is ironic to me that biologists who begin by being enthralled by the forms and workings of plants and animals sometimes end up analyzing them out of existence.”  (Susan Oyama, The Ontogeny of Information:  Developmental Systems and Information, 2d ed., rev. and exp., with a Foreword by Richard C. Lewontin (Durham, N.C.:  Duke University Press, 2000), p. 177.)

Reading Susan Oyama’s books on the battle among current genetic paradigms offers an experience not unlike observing wars among Western origin myths.  It feels less about which model is more useful and more about which views of the world feel intuitive to the theorists.  Intuitions often have social structure sources, informed by hormonal predilections.  That feels in play regarding genetic theory.  I find myself siding with Oyama, when I can understand her, but her tone suggests someone involved in a venture that is not fun.  She seems disgusted with the astonishing number of colleague-published accounts based upon hidden assumptions rather than upon observed conditions.

She cites dozens of academics I’m not familiar with, describing interpretations of genetic/environmental relationships in ways I find unfathomable, yet her point is clear.  Most male academics think that every living being in the world operates according to a set of instructions, less so by the relationships they form or the environment that they live in.

At this point, I feel comfortable interpreting the genetic algorithm outside the venue of individuals, as noted in the passage above.  Consider looking at any individual’s genes as shared resources of the larger system.  This view is accompanied by not looking at the individual as the level and context through which evolution operates.  This creates an opportunity to observe evolution outside our human obsession with noting parts, not wholes.

Natural selection as it emerged from the evolution theory synthesis in the mid-twentieth century often does not satisfactorily explain what we observe.  I believe one reason is that we are obsessed with interpreting the world from the scale of the individual, which happens to be the scale in which we as split-consciousness beings (self-aware beings) seem to spend most of our time.

Another reason is that implications of the new discipline, evolutionary developmental biology, are only beginning to be understood as regards the effects of social structure and the environment on maturation rates.

Both issues relate to autism.  The autistic often do NOT view the world from split-conscious awareness, but from a primary-process, presplit-consciousness orientation.  There is a world out there that exists outside materialistic, reductionist, cause-and-effect-relationship frames of reference.  A question is:  How do we integrate autistic and neurotypical paradigms?

If autism is a condition that can be partially explained by understanding how humans, species, ecosystems and systems in general mature, then perhaps we should be paying less attention to natural selection as a theory that offers solutions and more attention to alternative theories that concentrate specifically on maturation.

“The existence of mammary ridges on the embryo concording with ancient synapsids suggests that those ancient animals also had nutrient-supplying ridges on their bodies for which there is no paleontological evidence.  On the human embryo, the mammary ridges gradually coalesce and finally resolve into discrete nipples on day 58.  This event concords almost exactly with the lowermost Triassic, where the fossils of Cynognathus are found.  Discrete mammary glands and a fused secondary palate in the embryo coincide with a fused secondary palate in the fossil record.”  (Swan, Lawrence W. (1990) The concordance of ontogeny with phylogeny.  Bioscience 40: 380)

Because male humans differentiate from the foundation female at six weeks after conception, might this reflect an ancient emergence of testosterone after estrogen?  Might the Pre-Cambrian explosion have had something to do with there being no testosterone to call an end to the party?

“No one, least of all Williams and Kafatos, expect the eventual story to be so simple.  But it does seem likely that normal development is controlled by gradually decreasing concentration of a hormone acting primarily at high levels of the regulatory system.  This is also an ideal mechanism for the simple and rapid production of heterochronic…

Marian Annett and others have concluded that those anomalous dominant individuals with two cerebral hemispheres the same size often exhibit astonishing intelligence and creativity.  Michael Fitzgerald’s Autism and Creativity describes the kind of intelligence that sometimes accompanies these people.  The males of the group are often very maturational delayed.

Individuals severely traumatized in early childhood are often maturational delayed.  It’s as if large parts of them are unable to easily progress in a natural fashion.  Resources are tied to the trauma at the maturational stage they were in when the trauma occurred.  Therapy can unclench the individual from that stage.  Resources released, they can continue to grow.

Is it possible that early trauma can impact an individual to reproduce a neurological environment similar to that experienced by those naturally maturational delayed?  If so, can early trauma result in the exhibition of both the symptoms and the occasional remarkable intelligence and creativity exhibited by those individuals?

Those with Asperger’s, autism and other conditions exhibiting maturational delay, such as stuttering and phonetic dyslexia, often have unique brains, a predictable cluster of personality characteristics and behaviors featuring OCD, perfect pitch and other features.  Are there situations involving trauma where children without this familial…

Ten years ago, I was exploring the possible origin of human culture in tribal societies driven by rhythmic dance and music. Tribal societies are on rare occasions characterized by paternal anonymity, or children who are unaware of the identity of their biological father. Observing that human brain size began to diminish about 25,000 years ago, I hypothesized that this reflected an emerging patrifocal emphasis on speech instead of gesture and a movement away from a selection for big-brained males. If this was the case, I suspected that there might be remnants of the old matrifocal paradigm that still exist within contemporary society. In the neurological literature, I sought humans with unusually large brains, difficulty with language, but who were also ambidextrous or left-handed. I came to find that autistic individuals commonly display these features; in addition, I discovered that individuals with autism are often obsessed with pattern replication and have perfect pitch (Brenton, Devries, Barton, Minnich & Sokol, 2008).

It appeared that hidden beneath the just-so story was a theory, which, if brought to light, could help make useful predictions and illuminate unrecognized relationships. From the beginning, the theory drew information from three different disciplines: anthropology, evolutionary biology…

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.)

We have noted that Marian Annett observed a balanced polymorphism of gradations between random-handed and strong right-handed individuals within a society. We might conclude that just as there is a hypothesized random-handed prototype human and a strong right-handed prototype human, with some people fitting those exact prototypes, most folks in our four-pole hypothesis…

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…

The work of scientists is not often poetry. But they do reveal patterns that are profound.

“A corollary of our hypothesis is that hormonal effects on the brains of offspring may vary with the time of conception. The activity of the pineal gland changes seasonally with alterations in day length. As a general rule, during the dark winter months the pineal becomes active and suppresses both ovaries and testes, whereas in the summer it is inactive and sex hormone levels are higher. For this reason many animals bear young in the spring, an advantageous situation since temperature and food supplies are more suitable for survival. An example of such seasonal modulation of hormonal effects on the brain is observed in the HVc nucleus of the singing bird (Nottebohm 1981). This description of pineal physiology is, however, somewhat oversimplified. An animal’s sensitivity to light may vary through the year. Gonadal hormones may thus become activated in the spring, but as a result of loss of sensitivity to light over the summer hormone levels may diminish as fall approaches. Despite these facts, day length is a powerful influence. Thus, steers increase their weight more rapidly in the winter when artificial light is…

In ancient cultures across the world, there are myths describing a time when women controlled society with a magic more powerful than men’s. These stories go on to describe that there is a loss of the women’s power. Yet the stories also express that there still remains an awesome strength tied to female menstruation; the monthly moon blood is to be feared and respected.

Not unlike the experience of traveling to little-visited, far-flung corners of the earth and finding surprisingly similar myths describing origins of local culture; we find ourselves filled with a similar wonder upon traveling to little-visited academic sub-disciplines. Just as two far-apart aboriginal cultures might have no contact with each other, the heterochronic practitioners of evolutionary biology have little traffic with the neuropsychological theorists who may be located less than a hundred yards away in another building on the same campus. Strangely, we find these different scientists discussing identical processes in different terminologies with almost no published awareness that they have much in common.

How might two different scientific disciplines be discussing the same natural dynamic and not know it, like two aboriginal societies fearing menstrual blood half a world apart, unaware of another culture with the…

It could be said that it all begins in the womb. It is even deeper and more subtle than that. Autism researchers such as Simon Baron-Cohen are coming to the conclusion that a mother’s testosterone levels are influencing the likelihood of autism. I came to this same conclusion ten years ago exploring the work of Norman Geschwin and Charles Darwin. Noting this effect while exploring the impact of sexual selection on social structure provides additional perspective. Observing the relationship between social structure and evolution, one begins to understand that what goes on in the womb can decide the direction we evolve.

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

The higher the mother’s testosterone levels, the more likely the male children will have maturational delay and the females maturational acceleration. The males’ testosterone levels will be relatively lower compared to boys born from mothers with low testosterone levels. The females’ testosterone levels will be relatively higher compared to girls born from mothers with low testosterone levels.

When the mother’s testosterone levels are high, she is propelling her children backwards in evolutionary time. Backwards in evolutionary time for humans is away from patrifocal social structure…

Autism expert Simon Baron-Cohen has a theory that the autistic male shows evidence of a brain that is too male for his own good, the autistic personality being male to the extreme, evidencing exaggerated male characteristics. For example, the autistic is not just a little dissociated and abstract, but very dissociated and abstract. Baron-Cohen suggests that exposure to high levels of testosterone in the mother’s womb in combination with an absence of testosterone surges that prune early childhood synapse production that create a right-handed (as opposed to random-handed) person combine to encourage the emergence of autism.

Still enamored of natural selection, medical theorists explore the etiologies, or origins, of conditions and disorders encumbered by a theory structure that supports a narrow, patrifocal point of view. Informed by the fertile, earlier work of Norman Geschwin, Baron-Cohen has noted some of the most important clues to understanding how humans evolved and autism develops, but he is unable to see the larger picture.

Autism is an evolutionary condition. Ontogeny recapitulating phylogeny, Geschwin and Baron-Cohen’s clues are major interstate intersections on the roadmap of Homo sapien’s unfolding. When navigating across country, we look at the map and then use our eyes to read the…

There is a tribe of males more than a little infatuated with themselves and their own ideas. We’re often described as narcissists. Upon discovering I fit into this group, I was appalled, and predictably I obsessed that I was too obsessed with my own behavior.

I now look at myself as a recovering narcissist. I observe how frequently I engage in being a legend in my own mind. Sometimes I’m amused. Sometimes I’m not.

My wife is tolerant but not particularly amused. Interestingly, I come across few women narcissists.

Narcissism often gets relegated to an example of an early developmental stage that gets carried into adulthood as a result of trauma or a peculiar environment that caused a freezing of psychological resources in the past. This effect is not unlike following a recipe while making a cake. If at an early stage something goes awry, you may end up with a less than delightful outcome. Accidentally add salt instead of sugar early in the process and the results will be unique but not particularly edible.

I’m playing with the idea that there is healthy narcissism characterized by the person feeling accompanied while they feel they are the center of the…

There are many ways to kill a dragon. I counted several hundred strong-man dragon interventions in the almost one hundred books I read when I was snake-charmed by the subject. Courage, strength and cleverness were the qualities looked for in a dragon vanquisher. Many battles led to happy endings where the victor gained a wife.

Myths and legends are a little like spring garden catalogs, offering pictures of the ways a man can gain a mate along with instructions to society and its women on how to best encourage the man’s strong features. Our catalog of stories for the last few thousand years have offered guidance for the families of the women on how to pick strong, protective men for their grown-up little girls. When women began to pick their own husbands, they sought men with qualities that society respected, men with strength and streaks of independence, men who could be relied upon when dragons reared their heads.

Gilgamesh slew a dragon-like creature, a stand-in for the goddess, when records of these stories first emerged. Not just the Indo-Europeans, but Semitic, Asian and aboriginal peoples revel in these tales of acts of courage in gaining honor and a wife. Not…

I have friends with gaydar. Usually women, these friends can conclude a guy is gay after a brief conversation. I don’t think it’s the way they dress or the way they talk. It’s a childlike aspect they pick up on. When they are wrong, and the guy they thought was gay was not, that person had a Peter Pan quality about him.

When I was in college, I evidently jammed some guys’ gaydar. On occasion, I’d have to tell gay guys I was straight. I had girlfriends. It’s just that I was living out the life of my hero, Peter Pan. The Mary Martin version. If there was a major in childhood, I had the course load: children’s lit, art, children’s theatre, developmental psychology, clay, drawing, children’s clinical psychology, etc.

Many years later, when I fell in love for the first time I experienced a powerful connection between Wendy, as she was portrayed in the Mary Martin production of Peter Pan, and the woman I’d fallen in love with. It’s only now, more than 15 years later, that I fully realize why her wearing the Wendy-like white nightgown so filled me with reverence, fear and joy.

I’ve heard of the…
