Genetic memory is a real thing, really makes you think and im not being sarcastic. I've heard people speculate that this is one reason muricans got fat, was because of genetic memory of the famine of the 30s (lol)
Studying the biological basis for those effects in humans would be difficult. So Ressler and his colleague Brian Dias opted to study epigenetic inheritance in laboratory mice trained to fear the smell of acetophenone, a chemical the scent of which has been compared to those of cherries and almonds. He and Dias wafted the scent around a small chamber, while giving small electric shocks to male mice. The animals eventually learned to associate the scent with pain, shuddering in the presence of acetophenone even without a shock.
This reaction was passed on to their pups, Dias and Ressler report today in Nature Neuroscience1. Despite never having encountered acetophenone in their lives, the offspring exhibited increased sensitivity when introduced to its smell, shuddering more markedly in its presence compared with the descendants of mice that had been conditioned to be startled by a different smell or that had gone through no such conditioning. A third generation of mice — the 'grandchildren' — also inherited this reaction, as did mice conceived through in vitro fertilization with sperm from males sensitized to acetophenone. Similar experiments showed that the response can also be transmitted down from the mother.
Muricans got fat cos your food industry is completely out of control and lacks proper regulation. It's a problem in many other countries too, but Murica was the first to allow companies to put vast amounts of sugar in everything and then heavily market it to children.
One of the most prominent examples of our evolutionary programed faces recognition is the "Face on Mars" from a Viking 1 picture.
Our instincts are a mashup of prey fear, herd mentality, pack loyalty and predator aggression, all being ridden by a screaming monkey just about intelligent enough (on a good day) to plan for tomorrow.
Tighten that belt comrades. If you cut all programs you will soon be prosperous!
