Anything that is understood or known consciously is understood or known unconsciously first. I can’t imagine how the reverse would be true. Knowledge has to come from somewhere, right?

I often know I know something before the answer emerges. Knowing that I know, I trust that the answer will emerge, and so it does. We don’t often consider how long an insight or understanding has already been grasped before the veil lifts. I suspect hidden knowledge can stay hidden a very long time.

Hormone levels in humans fluctuate in response to a number of environmental influences. One of the most powerful and subtle is light. Cradled in equatorial Africa, our ancestors were exposed to the diurnal cycle of day and night. Human sexual hormone levels ran 24-hour cycles, as they do today, peaking and troughing at specific times in the cycle, with evenings about 30% lower than mornings.

Six weeks before a child is born, a crucial environmental trigger tells the child at what speed he or she will mature during his or her lifetime. The trigger is the amount of testosterone in the mother’s blood. High and low levels lead to very different outcomes of maturation speed. Change in the rate and timing of maturation is the single most powerful force that determines the evolution of our species.

The pineal gland can mediate testosterone levels, varying those levels according to the amount of light we are exposed to. It has been hypothesized that as light influences testosterone levels through the pineal gland, maturational trajectories vary over time.

The bun in the oven grows larger in a hormone stew. Studies conclude that the time of year a child is conceived influences the features of that child, specifically the child’s degree of maturational delay and acceleration. Autistic children’s birthdays congregate in specific seasons.

About 50,000 years ago, our ancestors departed Africa. Some anthropologists estimate they hugged the ocean and estuary shorelines, creeping or boating farther and farther from the equator. The farther from Africa’s equator that they traveled, the more light changed.

Seasonal changes in light caused radical changes in hormone levels, warping the short diurnal cycle in a second long wave pattern with overlapping variations. Children emerged with widely varying maturational speeds, creating the clay that would become the form that individuals in the culture would be molded from.

We can still see the results of equatorial societies plunged into the effects of varying light. African-Americans transplanted to the U. S. exhibit swings to the extremes of maturational delay and acceleration. We observe more autism and Asperger’s at the delay-end along with astonishing creativity around musical and physical proclivities. At the same time, faster-maturing, creative-in-a-different-way, more aggressive males congregate at the accelerated end of the spectrum. Jews run a similar pattern of maturational delay and acceleration, congregating at the maturational extremes. These two ethnic societies hold far more maturational variation than cultures that have not recently been upended. With the increased variation come gifts. And, there are the burdens imposed by a society not compelled to seek the assimilation of unconventional characteristics.

Stable cultures have a chance to adjust to the light of their location on the planet.

It is only now becoming evident that light can transform the features of our children, the characteristics of our culture and the direction that our species evolves. Perhaps, unconsciously, we’ve known this all along.

    I don't think my life is organized enough to do something completely different for a break. Every part of my day seems different, and at this point its rather exciting. I sing, play instruments, bang random cans, make jewelery, play board games, take a drawing class, laundry, wrastle with the kids, dance, cuddle. This is a good life. I recognized the picture of you AGAIN! A year of drawing faces is going to be so great for you to look over and see progress. I'm excited for where you're going. Love yoU!

    I LOVED Pushing Daisies. And I watch Moonlight any chance I can find it. But Alex has moved onto Hawaii 50, so the chances of Moonlight coming back would seem to be nil.

    Si lo que acordó al momento de dejar la seña difiere de lo que se le solicita para la firma del contrato, está siendo victima de una estafa. Recurra a un abogado para detener el actuar de esos delincuentes y evitar que usted sea una victima mas.
