Recent research findings indicate that we are part of a diverse ethnic pool. This has significant implications for how we understand our bodies and minds. Our genetic make up and our environment all influence who we are and how we perceive and receive the world.
For instance, the New Scientist article “ D may increase IVF success – for some people”[i] explained how looking to confirm that vitamin D plays a role in conceiving, Briana Rudick, at Columbia University Medical Center in New York, and colleagues compared vitamin D levels and IVF success rates in 188 white and Asian women. White women who had the recommended level of vitamin D were four times more likely to get pregnant than white women who were deficient in the vitamin. The reverse was true for Asian women – those with the lowest vitamin D levels were most likely to get pregnant (Rudick et al, 2012)[ii].
In other words, the use of vitamin D by the body varies in accordance to our ethnicity. Each human species has its own particularities originally based on environmental needs. This kind of reversal of the roles of vitamins within different ethnics is very important to consider and can be very dangerous.
Turns out, our genetic history has a direct impact on our health. But it is also known that the environment affects our genetic body as well. Geneticists now know that RNA, the junk DNA, is not junk but the adaptable part of our genes. They react to environmental stimuli and signal the DNA to change the type of protein it produces, depending on what the environment requires. DNA is not all pre-programmed; RNA changes the programming to fit the environment (Heinrichs, 2012)[iii].
I would not be surprised if in the case of extremely highly multi-sensory gifted children the only way to survive over-stimulation is to shut down their communication and sensory systems in order not to go insane. Signaling the genes to shut off sensory inputs to save the person. These environmental genetic changes are not the only factor influencing how we are evolving. It has been know for along time that our environments influence our behavior and health. As we will explore next.
