Evolution takes place because we successfully adapt to changes in our environments over vast amounts of time, leading to the false belief that evolution occurs only when the environmental change is stable over time so that the adaptive changes can take hold and the species can flourish. After all, if the adaptative pressure goes in one direction and then reverses course, the adaptive changes might never happen or become maladaptive and cause extinction. But the climatic record during human evolution has been extremely variable, especially in the recent past, so it does not support the idea that environmental stability produced our adaptation. This post will discuss the accepted definition of ice ages, glaciations, interglacials, and their effect on human evolution.
Read MoreWe hunted and gathered food found exclusively in the outdoor environment. As such, we evolved to be outdoors in the Sun for much of the day. Therefore, the advice given by dermatologists to avoid the Sun runs contrary to the evolutionary evidence. New information about the human body's optical qualities is reshaping our stance against sunshine. Near-infrared (NIR) light penetrates deeply into our body, unlike UV and visible light. Evolutionarily, the human body has developed optical mechanisms to gather and localize NIR photons in the most sensitive areas of the human body: blood vessels, retina, brain, skin, and even the womb. Research has demonstrated that NIR stimulates the production of antioxidants deep within our cells at the sub-cellular level. We use the reservoir of antioxidants to enhance the body's ability to contend with changing conditions throughout the day. I will cover some amazing things light does for our health and how you can maximize your light exposure.
Read MoreAs an active clinician with an insatiable appetite for knowledge, I am always searching for new perspectives on our poor health. Sometimes I find antique descriptions of current health problems. I recently found and read a book by George Catlin on how our children can achieve beautiful faces and superior health by ensuring that they sleep with their mouths closed. I had thought this knowledge to be a recent scientific finding, so naturally, I was intrigued and read the book in a few short hours. I was highly impressed with the Native American wisdom he shared. Sadly, the knowledge was largely forgotten and is only followed by a few people today. Here's some of what I learned...
Read MoreBefore the advent of farming, our jaws were larger; our faces were broader, our teeth were straight, we had adequate room for our wisdom teeth, larger brains, and more space in our throats to breathe. It is a virtual certainty that our changing diets contributed to crooked teeth and a lack of adequate space for wisdom teeth and constricted airways. SMALL JAWS CAUSE BIG PROBLEMS. Heart disease, cancer, Alzheimer's disease, ADHD, depression, and anxiety are a few. In this post, I am going to cover how our lifestyles have changed leading to our current problems, and what we can do about it.
Read MoreThe modern history of the discovery of vitamin C is an interesting one, and, as you will see, we are still uncovering new information about its role in our health. More interesting is the evolutionary history of vitamin C metabolism in humans, which is somewhat unique among the animal kingdom, and has led to confusion over the amount we need in our diet. This post will set the record straight.
Read MoreAlthough there are several ways our diets have diverged from our ancient ancestors, today, I want to especially touch upon the two primary ingredients in our food supply, causing untold havoc on our health and well-being.
