In biology, Cell receptors are markers on the outside of the Cell that recognise and allow passage through the membrane, molecules that fit the specific shape and function specificity of the cell receptor. Also proteins inside the body have their own version of recognising their target molecule through shape / function specificity that matches the protein's own function specificity. All things made to work in streamlined benefit for the organism. What happens when there is outside influences that affect the environmental parameters, such as temperature and humidity, pressure (or being eaten by different kinds of predators) exerting environmental stress on the organism??? The organic biological organism may experience a breaching of its natural internal environment and allow through into its systems, different types of protein molecules, such as other enzymes, in response to the situation, for example in fear... we have the fight or flight responses come to the fore, OR allowing opposing or detrimental 'viruses,' poisons to that system that wouldn't be allowed passage otherwise. The same is true for people, who have been under an 'exerting' influence that causes their natural state of optimal health to be compromised. When in any condition the organism will respond. When in optimal conditions, there is growth and thriving and even evolution....When in stasis, all things being adequate, there is no flux, neither in decline nor in advancement. When conditions do not yield food, the organism dies or finds something else to eat. When severely compromised, caused by undue stresses in their environment, the cell-receptors, the cell, the organism, the people....(as when their biological stronghold is attacked), they shift gear into either defence mode, and become weakened with an accelerated detrimental auto-immune response OR they are shifted into having an accelerated biological functionality and have their 'specificity' rearranged for them. I know a lot of people question Darwin saying we were not monkeys...but I think the poignancy of Darwin's theory of evolution was really about creature's natural capacity and inbuilt equipment to adapting to the changes (forced or naturally occurring) in their environments or a complete loss of that species type. Those that managed complete mastery within the parameters of the changes in the environment were seen to be the winners and those that could not, died out. The point being made here is that pressures exerting on the human experience, both in the biological systems, combined with the mental/ spiritual and emotional soup we find ourselves in now....can ONLY produce either, a detrimental auto -immune response , which can go either way, including the Effort to survive... OR allow the blossoming of a whole new species of human that targets 'thriving' as the mission statement going forward. Transmission ends, Michaela.
