The Hypothesis posits that evolution designed us to function perfectly. Our phenotype does not match that genotype because humans make a choice (we don’t frequently exercise with sufficient intensity) that causes our environment to vary from the normal evolutionary environment. Insufficient exercise equates to lack of food or air or sunlight. The Hypothesis further posits that a primary reason that intense exercise is essential for a normal environment is that intense exercise, or rather certain chemicals that we synthesize whenever we engage in intense exercise, is how we activate the Growth Process.
Entropy, which wears down everything in the universe, is constantly causing minor damage to all humans. The aging process is the result of the accretion of years of physiological damage at the cellular level, which ultimately causes organs and systems to malfunction. A conundrum for the scientists has always been – why don’t humans have a maintenance process that fixes that minor deterioration? Humans have a healing process. We have an immune system. Why don’t we have a process that repairs the slow physiological deterioration that results from entropy?
Evolution works through the process of natural selection -- choosing those traits that enhance an organism’s likelihood for surviving and reproducing. The key to enhancing the likelihood of surviving and reproducing is, of course, ensuring functionality. When humans suffer the “infirmities of aging,” one of the earliest symptoms is the dysfunctionality of the skeletal muscle system. We slow down and get weaker. And it shows up in our 20s and 30s. In the natural world, that slowing down is fatal. If humans were subject to the forces of nature, the result of the aging process being inevitable would be that no humans would survive beyond about the age of 30.
But suppose evolution provided humans with a maintenance process. That process would maintain functionality of not only the skeletal muscle system, but also all other organs and systems, including the reproductive system. Such humans would be able to not only survive, but also to reproduce for so long as they were able to avoid other causes of death. A perfectly functioning human who survived into his 60s would have far more likelihood of reproducing than one who died in his 20s.
In other words, if evolution worked the way we all thought it did, humans would have a maintenance process that would prevent us from breaking down and losing functionality as we age.
Stop here for a second. Digest that thought. Apply logic rather than what you “know” to be true. The Theory of Evolution predicts that humans should have a process that prevents us from breaking down as we age. Either we have a maintenance process that ensures that we maintain optimal functionality throughout our lifespans, or evolution made a mistake. Or perhaps the Theory of Evolution is just wrong.
The Hypothesis explains that the Theory of Evolution is fine. The Theory predicts genotype, not phenotype. We are all genetically endowed with a Growth Process, which is an improved version of a maintenance process. We just fail to activate it.
Infants and children are subject to the same forces of entropy as are adults. But because children frequently activate the Growth Process, they historically have not shown the big deviations between genotype and phenotype that are symptomatic of the aging process. Scientists assume that either the Growth Process is nothing more than the genetic instructions themselves, or that the Growth Process terminates once we achieve our maximum height or reproductive maturity. The Hypothesis provides compelling evidence that the Growth Process is a separate and distinct bodily function that involves dramatic changes in body chemistry. But it only occurs when it is activated. That’s true of both children and adults.
The bodies of healthy people (people who aren't suffering from FDS) are constantly producing all of the substances that are involved in the Growth Process - human growth hormone and other growth hormones, steroids, stem cells, brain-derived neurotrophic factor, etc. But these substances last for only a short period of time in the bloodstream and cannot work on their own. Moreover, the Growth Process uses a lot of energy. Thus, the Growth Process cannot operate continuously. For example, the pituitary gland, which produces HGH, will store the HGH until it is given the signal that the Growth Process has been activated. That signal is the increase in blood levels of Complex X. When that occurs, the Complex X signals the release into the blood of all of the component substances, and the Complex X provides the extra energy that is necessary to fuel the Growth Process without compromising the brain's need for a constant supply of blood glucose.
There is no abrupt termination of any bodily process, including the Growth Process. The Growth Process is genetically programmed to operate whenever activated throughout our lifespans. We don’t stop getting taller because the Growth Process terminates. Our final height is determined by the fusing of the relevant bones in a manner that makes further lengthening of those bones impossible. But all organs and systems in the body grow or develop whenever we activate the Growth Process.
