A hazy dynamic is emerging in my mind.  This possibility has bounced around in my rear thoughts for several years along with the riddle of Asian patrifocal neoteny.  The dynamic is as follows.

As outlined on numerous occasions within this blog, testosterone levels are hypothesized to compel human neoteny and acceleration-driven biological and social evolution, on occasion compelling extreme maturational delay such as autism, simulating what appears to be teleological intervention (evolutionary overarching patterns that have been hypothesized to represent the presence of an interventionist deity).  At six weeks before birth, mother’s testosterone levels establish her child’s lifelong maturational trajectory and which social structure will feel like home when that child is grown.  High testosterone mothers birth high testosterone daughters and low testosterone males who fit into a matrifocal paradigm.  Low testosterone mothers create low testosterone girls and high testosterone boys feeling at home amongst patrifocal folks.

Consider that estrogen levels also compel progeny trajectories based on the mother’s estrogen levels at a certain point in her child’s embryonic career.  Let’s hypothesize that low female estrogen levels result in small body size and an inclination toward patrifocal social structure where female infanticide is common.  High female estrogen would incline the female toward matrifocal social structure where it would not be considered that infanticide could serve society goals.

If by chance a person’s estrogen-influenced characteristics, including that person’s estrogen levels, are established by the mother’s levels of estrogen at some point late in embryonic ontogeny, then children born premature, premature before that day that embryonic estrogen has been established, will probably exhibit features mildly to radically diverging from other siblings.

I’ve not investigated the testosterone-influenced maturation rates of individuals surviving premature births occurring before the sixth week (when testosterone levels and maturation rates are set) before a normal 38-39 week gestation.  Anecdotal evidence suggests there are effects, for example, females exhibiting high testosterone personalities.  Establishing high and low estrogen physiological/psychological features and comparing that to various premature birth estrogen-related physiological/psychological features might reveal a biological/social evolution-informing estrogen dynamic.

The million-dollar question is whether high estrogen mothers birth high estrogen daughters, low estrogen sons while low estrogen mothers birth low estrogen daughters and high estrogen sons.

This would, of course, mirror and complement the testosterone paradigm.

What evidence would support this premise?  What are the implications?  What riddles are hanging out there that this second dynamic just might resolve?

What led me to this set of conjectures is the riddle of highly patrifocal Asian cultures exhibiting neoteny contrasted with Scandinavian societies exhibiting a different assortment of neotenous characteristics while living cooperative, care-based matrifocal lives.  (See Estrogen Riddle, previous entry)

While untying this knot, I’m assuming that we were created artfully and playfully.  In addition, let’s explore this hypothesis for its potential to be real.  Any academicians or amateurs like me out there that know of papers that support, disrupt or point to an alternative hypothesis?
