The Story of the Human Body – Evolution, Health and Disease.
Evolutionary biologist, Daniel Lieberman in his book ‘The Story of the Human Body’ suggested that medicine could benefit from a dose of evolution. Whilst evolution may appear irrelevant to medicine at first glance, our body is not engineered like a car; rather it evolved over time with modification. It therefore follows that knowing your body’s evolutionary history helps us understand why your body looks and works as it does, hence why you get sick.
Although scientific fields such as physiology and biochemistry can help us understand the proximate mechanisms that underlie a disease, evolutionary medicine helps us make sense of why the disease occurs in the first place.
Over time, natural selection adapts (matches) organisms to particular environmental conditions and this process occurs over tens of thousands of years. Research suggested that it takes 40,000 to 100,000 years for an environmental change to assimilated (genetically) by the body.
However, as innovation has accelerated, initially since farming began (approximately 2,000 to 10,000 years ago), and especially over the last few hundred years as a result of the industrial and technological revolutions, we have devised or adopted a growing list of novel cultural practices that have conflicting effects on our bodies. Many of these cultural changes have altered interactions between our genes and our environments in ways that contribute to a wide range of health problems known as mismatch diseases – which are defined as diseases that result from our Paleolithic bodies being poorly or inadequately adapted to certain modern behaviours and conditions.
Most mismatch diseases occur when a common stimulus either increases or decreases beyond levels for which the body is adapted, or when the body is not adapted for it at all. Moreover a common characteristic of these diseases, is that they occur from interactions whose cause and effect are not immediate or otherwise obvious. And most of these mismatch diseases are ailments that, as far as we can tell, were rare in our Paleolithic ancestors.
In other words, we get sick because we do what we evolved to do in an environment to which we have not adapted, and then pass these habits and illnesses onto future generations, who also get sick..
Hypothesised mismatch diseases account for a vast majority of deaths in the modern Western World. These are the chronic, insidious onset ailments that include heart disease, cancers (some), stroke, diabetes (Type II), obesity, chronic respiratory conditions, cavities, apnoea, chronic fatigue syndrome, fibromyalgia, ADHD, depression, anxiety, insomnia, IBS/Crohn’s disease, OCD, hypertension Alzheimer’s disease to name a few.
Following this understanding, it makes sense that in preventing and treating these mismatch diseases, we apply what is understood of how we lived and therefore, how our bodies are structured to function ideally.
The aspects of living that most impact our health include:
- How we move and stabilise
- How we think and emote – which influences how we process stress (which subsequently affects all other aspects of living).
This is the primary influence or core philosophy in my approach to treatment and prevention of disease, performance and optimal living. Using what understanding we have of how we performed these aspects of living as we were evolving and applying this in an approach to treatment or living can yield outstanding and life changing results. And, over time, it reduces or eliminates the need or reliance on synthetic or artificial medicines.
Further, the use of accurate and reliable biofeedback to provide information on the efficiency that one is achieving in performing these aspects of living, makes learning much easier and more rapid.
Finally, the use of pure extracts as medicines and supplements, where necessary, provide the perfect balance. As opposed to manufactures and synthetic, or new to nature, pharmaceuticals and supplements, pure extract herbs and nutritional medicines exist in the form that our bodies were exposed to them over millions of years and are therefore far more easily assimilated, or are more bio-available than artificial chemicals and lead to no side effects as a result.
Modalities used to bring about recoveries from these chronic illnesses include:
- Mickel Therapy – which addresses imbalance at higher levels – specifically, the hypothalamus which regulates all automatic functions, endocrine function, immune, cognitive function, sleep cycles, neurotransmitters etc.
- Nutritional medicine
- Breathing retraining
- Therapeutic fasting
- Herbal medicine
The more we begin to understand how nature has adapted us to live and living our lives in accord with this, and using foods and medicines provided to us by nature throughout our evolutionary history, the more we will shift the focus of medicine from treatment to prevention and optimal living.
