From the Genesis Garden to Galapagos and Back
By Bill Sardi

At a birthday party for a 70-year-old relative on my wife’s side of the family, I met one of his sons, in his 40s. His son had never been raised by his biological father, having lived out of State all his growing and adult years. Father and son had only belatedly become acquainted, as they had talked on the phone many times, and were physically meeting for the first time at this party.

It was interesting to observe that father and son had similar mannerisms, physically and verbally. It was striking.

Biologists think they now know what is responsible for this observed phenomenon: genes have memory. Oh, not memory in their structure (DNA ladder) but in their switching. You see, human genes are not only organized in a sequential spiral ladder of 25,000 or so-called lettered genes (a deletion or substitution in the letters results in a gene mutation), genes also have switching mechanisms that can cause a gene to produce or not produce proteins (what biologists call gene expression or gene silencing). This switching mechanism is called epigenetics and it is actively in play every moment of life, influenced by environmental factors such as temperature, food, radiation, and surprisingly, behavior.

A relatively new discovery is that via gene switching (epigenetics), your genes can be imprinted in a semi-permanent fashion that is transmitted to future generations.

The biological phenomenon called epigenetics has been known since the 1970s, but for unexplained reasons, not really discussed at large till recently. Keeping epigenetics obscure may have served a purpose – to advance and maintain the fading idea of Darwinian biology. Darwinian evolution demands millions of years for mutations to occur, whereas epigenetics is now.
