We are playing with the concept of four prototype pairings, with eight prototype human beings. We are estimating that because the mother, at six weeks before birth, sets her children’s testosterone levels based upon her own testosterone levels (mother with high testosterone T creates a low t male and a high T female while a mother with low t creates a low t female and a high T male) that estrogen will run a similar dynamic. 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.

F te/M TE Conventional Patrifocal
F tE/M Te Warrior Patrifocal
F Te/M tE Contemporary Matrifocal
F TE/M te Classic Matrifocal

F te/M TE means low-testosterone & estrogen females, high-testosterone & estrogen male. Domineering, caring, discriminating men choosing cooperative women.

F tE/M Te means low-testosterone, high-estrogen female, high-testosterone, low-estrogen male. Domineering men choosing cooperative, caring, discriminating women.

F Te/M tE means high-testosterone, low-estrogen female, low-testosterone, high-estrogen male. Commanding women choosing creative, cooperative, caring, discriminating men.

F TE/M te means high-testosterone & estrogen female, low-testosterone & estrogen male. Commanding, caring, discriminating women choosing creative, cooperative, aloof men.

We now have two complementing dynamics acting as the engine behind social change and evolution.

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 either influencing maturation rates and timing (via testosterone) or by influencing the intensity of mate selection criteria (via estrogen), thus modifying the trajectory of social and human evolution.

We have here a kind of Silly Putty model of human social and biological transformation. There are numerous impact points that can result in change, many forces that can mold humans. I’ve been calling this the Theory of Waves, noting the impact of neoteny and acceleration on human biological and social evolution. That was when I was observing only the effects of testosterone. The name still holds, except now we are hypothetically observing the effects of estrogen coursing through this system, compelling the waxing and waning of sexual selection, focus on aesthetics and caregiving, and perhaps the aesthetic architecture supporting culture.

In an earlier piece (Minnesota Somali Autism: Geography and Light), I hypothesized that because diurnal light cycles affect the pineal gland (see Geschwind and Galaburda, 1987), equatorial peoples that migrate to northern climates would experience an increase in autism. This change would occur because the pineal gland would interpret long winters and summers as an equatorial night or day, and thus it would act differently when regulating very high or low thresholds of testosterone in the mother’s womb.

Supporting this conjecture are studies that suggest the conclusion that both Black and Jewish populations, transplanted from their African or near-Africa origins, reveal both extreme maturational delay and acceleration in their male populations. These effects would result from seasonal variations in testosterone in their mother’s wombs. Indeed, studies reveal seasonal effects in the conditions that accompany extreme maturational delay and acceleration and diseases such as prostate cancer that are accompanied by unusually high testosterone levels.

There is also the possibility of multigenerational reverberation effects. Second-generation women with exaggerated hormonal levels with accompanying maturational delay or acceleration manifesting in very high or low testosterone levels in the womb may experience their womb conditions amplified if, at the sixth week before birth, the season is again one characterized by either extreme dark or light, thus mirroring their own birth conditions.

Another potential impact is the possibility that males pass on to their progeny their body’s maturation rate proclivity based upon their mother’s uterine environment. This information would be picked up during their lifetime, early in ontogeny. It’s also possible to hypothesize that the testosterone-influencing light environment during sperm creation impacts the maturation rate of his children. If either of these conjectures holds true, then the issues to be explored by evolutionary developmental biologists examining the steering mechanism of the engine of social and human evolution become exponentially more flexible.

Unexamined are the potential effects of the dynamics we are discussing on a population of humans leaving Africa between 50,000 and 60,000 years ago. Testosterone and hypothetically estrogen both come into play. The emergence of signs of culture in Europe may be directly related to the same effects observed to occur on populations of Blacks and Jews noted above, with a proliferation of unique hormonal types branching out from an equatorial hormonal constellation convention.

I would hypothesize Classic Matrifocal (F TE/M te) populations moving from Africa into Europe. As malleable as human populations evidently are, we might conclude that any of the four prototypes wandered out or that single populations morphed from one type to another over time. It’s possible that different populations occasionally intermixed. Regardless, a tendency toward abstract speech communication, evidenced by males with a new split brain and a smaller corpus callosum, impacted by the changes of light and modified womb testosterone levels, could have been propelled far deeper and faster in the direction of language proficiency when becoming accelerated in maturation.

Mirroring these changes in males leading to spoken language and an ability to manipulate time (see earlier essays noting my hypothesis that females had already evolved these abilities), females may also have been influenced by their environment, perhaps by increases in fats and nutrients, which result in higher testosterone and estrogen levels. Enhanced estrogen may have made them far more discriminating in the males that they chose for mates. (Venus figurines may be portraying the high-testosterone, high-estrogen, overweight woman.) Split-brain males may have been becoming far more adept at producing cultural artifacts, taking advantage of their newfound ability to speak articulately and control time, with the most adept males being chosen as mates.

The sudden emergence of culture may have been influenced by changes in light that affect testosterone levels that guide maturation rates. Estrogen levels may have also been influenced by the new environment, which was compelling a more refined female aesthetic. They would have been culling out those males who were affected positively by the changes in light.

These are deeply hypothetical conjectures, but they give you an idea of how to play with the Rubik’s Cube, Silly Putty platform of ideas that comes when you notice how malleable we are. The effect becomes all the more noticeable when we appreciate how testosterone (maturation rate) and estrogen (caregiving and sexual selection proclivity) influence transformation.

    アトピー性皮膚炎の改善に用いられるのがステロイド軟膏です。対処療法になりますが、かゆみや炎症を抑える作用があるため、アトピー性皮膚炎の症状緩和には有効です。ステロイドはほかにも、副腎皮質ホルモンと呼んだりします。ステロイド軟膏は病院で処方されることが一般的ですが、インターネットを使って買うことも可能です。Strong以下のレベルであればamazonなどでも買えますし、StrongestやVeryStrongなどの強いレベルのステロイド剤であっても、個人輸入という方法で買うことが可能です。外国から発送されるため商品が到着するまで少し時間がかかりますが、それ以外は通常のネット通販とほとんど同じです。
