If modern humans originated in East Africa, there can be no doubt that their
initial migrations took them to Asia. And, as I imply in the prior section, this
probably took place in fugue-like fashion as one group set out, to be followed
by another, and another. We know this migration was quite ancient, since remains
of Homo erectus, who were probably ancestral to modern humans, have been found
as far as Pakistan and China.
There was a significant warm interglacial period between 100,000 and 150,000
years ago and a greener Sahara allowed humans living in Ethiopia and the southern
Sudan to travel north across an otherwise impenetrable Sahara and Sinai Peninsula.
However there was again another sudden freezing of the world’s climates about
90,000 years ago, and this saw the return of desert conditions to the Middle
East with the loss of major game.
The migration from the Middle East into Europe - the presumed route by those
early Homo sapiens- would have looked very different than a similar voyage embarked
upon nowadays. They would have had to pass through a belt of extreme arid semi-desert
conditions that extended from North Africa almost to the foothills of Armenia
in the Caucuses. From there they would have encountered an almost endless expanse
of dreary tundra, interrupted solely by dense stands of boreal forest in the
Carpathian basin (modern day Hungary) and the headwaters of the Danube, around
present day Austria.
These forests would continue to grow and spread out over Western Europe, making
it difficult for the larger land animals, which were voracious herbivores, to
survive. In their ultimately failed attempts to do so, these large mammals began
to migrate east with the shrinking tundra forcing upon these early Homo sapiens
one of two choices: Stay put or keep moving west and come to terms with the encroaching
forest, or move eastward with the large mammals. Those who stayed became the
hunter-gatherers of the forests and fishers of the numerous rivers, bays, and
shallow waters connected to the seas of Europe. Those who moved east hunted
out the last of wild big game and turned their best efforts into learning to
herd what was left.
Heading further north, the tundra would have extended to about the area of modern
day Denmark; since it is only there that we find the remains of Scandinavian
ice-age animals older than 13,000 BCE. A large part of what is today the North
Sea was dry land connecting Denmark with Britain, and the earliest inhabitants
of The British Isles almost certainly walked there.
If instead Hunter turned south, to what is now Greece, Southern Italy, all the
large Mediterranean islands, and the coastal areas of Turkey and Spain, the vegetation
would resemble a semi-desert steppe with scattered pockets of trees in the moist
areas: it was certainly a more wooded landscape than we would find taking a similar
trip there today, as all these areas have been extensively deforested over the
last two thousand years.
In North America, the dominant feature was the presence of a vast ice sheet almost completely covering Canada. Forest dominated the eastern USA, but it was more open in character and contained trees adapted to the cooler climates.
In the Cordillera region of the western USA, the areas below 500 meters altitude
were semi-desert and scrub from 500 meters up to 1500 meters. This was also true
for the whole Sonoran Desert area to the south and covering Texas and northern
South America was slightly cooler and generally drier than at present. It appears that the Amazonian rainforest was substantially reduced in area (though large uncertainties remain). The Atlantic forest of Brazil was also much diminished. Some desert and semi-desert areas formed in what are presently grassland and scrub zones.
The human habitation of the Americans began about 15,000 years ago although some
archeologists place it as far back as 30,000 years ago. These early colonists
almost certainly crossed the Beringia land bridge, which existed between Siberia
and Alaska at that time of the Last Glacial Maximum. Linguistic evidence seems
to indicate that they came in several waves.
The Americas had an almost complete extinction of large mammals by the time of the arrival of the Europeans in the 15th century, so much so that their horses were a source of amazement and fright. It has been argued that the extinction of large game was a consequence of the terrific hunting skills possessed by these migrating Asian hunters, but other evidence points to changes in the vegetation at the end of the last glacial period.
Originally forest hunters advancing and retreating along the outskirts of the
boreal and tropical woodlands with each change in climate, Hunter GenoTypes are
acutely tuned and flexible in their reactions, which perhaps explains why as
a human technology they have been so historically successful - and why they continue
to adapt to new conditions and challenges.
Hunter Genotype is one of the true success stories in our history as a species.
They are highly charged, kinetic people with a constant need for a physical outlet
- human electrons, if you will. When in shape, they are capable of prodigious
physical effort and as such make for some of the best, most 'natural' athletes
to be found in sports. If you need a quick metaphor for the Hunter metabolism,
just think of those turn of the century steamships with their glowing coal furnaces
buried deep down inside of the hull of the ship. Yet like the heart of a thoroughbred
racer, they run and run, often until their heart bursts.
Tall, thin, and intense, with an overabundance of adrenaline and a fierce, nervous energy that winds down with age, the Hunter was originally the success story of the human species. Vulnerable to systemic burnout when overstressed, the Hunter's modern challenge is to conserve energy for the long haul.
The Hunter Genodynamic is reactive, adversarial, and opportunistic - basically
a phenomenal combination for survival.
Typically, Hunters are long-legged, with lower legs longer than upper legs and total leg length greater than torso length. They are often lean and long (classic ectomorphs, really) but also can range to meso-ectomorphic as well, with perhaps the distinguishing feature being the fact that meso-ectomorphic Hunters tend to have denser bones but a smaller frame size. Caucasian Hunters almost always broad-headed and often have lighter hued hair; not necessarily blonde, but a broad spectrum of lighter hues of brown. In Africans, Hunters tend to have a Capoid facial structure, with a nasal index that points to a narrower nasal ridge. Biometrically, Hunters almost always have at least one hand that is testosterogenic (ring finger longer than index finger) and many, especially men, have both hands symmetrical for this. This feature and all that growth factor activity in early life are what make Hunters the natural athletes they are.
Because they typically function at such a high level of output, the Hunter rarely
sickens in an over-energetic fashion, rather more likely rapidly falling into
one of any types of exhaustive states. In these circumstances they can have problems
regulating their blood sugar, especially if they are deconditioned from a history
of sedentary behavior. Earlier in life, with all their resources at peak function,
Hunters can develop a sort of free floating anxiety, occasioned by difficulties
in their ability to clear adrenaline effectively from their bodies. These higher
levels of adrenaline can often compromise their appetite and appreciation for
the texture and flavor of food, and it is not uncommon for Hunters to complain
during adolescence and early adulthood that they have difficulty keeping their
At their best, Hunters have an absolutely superb metabolism - perhaps the best
of the six GenoTypes. They have a positive genius for converting calories into
the perfect combination of muscle, bone, and fat, and their physiques are primed
for optimal use of their lean athletic limbs and long, strong backs. If you're
a Hunter you might think of yourself as a top-of-the-line sports car that burns
high-octane fuel - and then ask yourself what happens to that Porsche if it gets
poor-quality gasoline or isn't driven at the top speeds it was designed for.
In their book, The Fetal Matrix, Gluckman and Hanson make a strong point
that our early Paleolithic hunter-gatherer ancestors may have done a better job
of 'getting it right.' These so called happy Paleo people no doubt inhabited
a world fraught with difficulties, but the hunter gatherer diet, with its reliance
on animal protein, would certainly have provided a continuous source of nutrients
to their diet even if it was intermittent and sporadic. Other methods of complimenting
the diet, such a foraging and perhaps even some light, subsistence agriculture,
would have completed what even by our standards of today could be considered
a fairly wholesome diet. Since the diet of these individuals was largely in keeping
with what would have been anticipated from generation to generation, there really
would not have been much of a 'disconnect' between the generations; in other
words, what would have been predicted by environmental conditions and programmed
in the womb would have been fairly close to what would have been encountered
in life; and indeed, evidence would suggest that these people were fairly healthy.
Subsequent to this so called 'Happy Paleo Period' there appeared to be a long
process of adjustment to the later Neolithic type existence with its emphasis
on a less migratory, more settled existence and increasing reliance on subsistence
agricultural and simple animal domestication. These must not have been easy times;
the diet would probably have been lacking in some important components. As mentioned
earlier from 'Happy Paleo' to subsistence Neolithic may have been the germ of
an idea that was later encapsulated in the Bible as the tale of the expulsion
from the Garden of Eden. Of course, no one argues that the effects of agriculture
and animal husbandry have gone on to do nothing less than revolutionize the human
experience. We and our offspring at least for the foreseeable future live in
the so called 'age of plenty,' characterized by phenomenally productive agricultural
Of course, this has also gone on to become the root of many of our health problems,
and one bill that does remain to be paid involves the effects of the thrifty
phenotype, developed over the course of many generations in countries like China
and India which have experienced a long history of subsistence agriculture, famine,
and food shortages. The million dollar question remains: what will happen to
these populations, as increasing affluence and the high calorie western diet
meets generations of thrifty phenotype programming? The implications are chilling
if you are willing to admit that we in the west are currently undergoing our
own epidemic of diabetes and obesity and cardiovascular disease, for if that
is the case, the sheer numbers of possible cases of these very same problems
worldwide and their resistance to cost-effective treatment does not bode well
for the future.
No surprise, Hunter possesses a truly amazing set of predictives for hunter-gathering.
However unlike several of the other reactive/thrifty genotypes, Hunter is moderately
well-adapted to the present day set of environmental conditions as well. Perhaps
this is the result of a long tradition of superlative maternal effects due to
the genotype possessing many of the requirements for optimum nurturing: High
gestational levels of oxygen, insulin and growth factors, often the result of
the mother being a Hunter as well, and being perhaps a bit more inclined towards
a high protein diet.
Hunter dermatoglyphics (fingerprint patterns occurrence and distribution) show no strong associations, suggesting that this genotype is a product of vigorous and effective prenatal gestational processes, which is a reflection of their lack of thriftiness and ability to burn through calories at a prodigious rate. If you haven't been eating right for your GenoType, you'll probably have done some damage to the lining of your digestive tract and having worn fingerprints with lots of white lines will let you know that's the case.
In other words, when you can make a decent fingerprint, you can make a decent lining for your gut as well. Perhaps no surprise, white lines have been linked to celiac disease, a condition of gluten sensitivity.
Ancestry and Variants
Hunters often have variations (polymorphisms) in several of the common nutritionally
significant genes. These polymorphisms fall into two very general categories:
pro-inflammatory genes and genes which indirectly modules inflammation due to
their ability to activate anti-oxidants:
Proinflammatory and antioxidant gene polymorphisms are common to Hunter.
- Il-6: This gene codes for interleukin 6, a hormone (cytokine) of the immune system
- TNF-a: This gene codes for tumor necrosis factor a cytokine that plays a role in maintain bone health and controlling inflammation
- SOD3: This gene codes for superoxide dismutase an enzyme that is used as an antioxidant and for cardiovascular health.
- MnSOD This gene codes for manganese superoxide dismutase, a mitochondrial enzyme that plays a key role in protecting the cell from oxidative damage.
DNA Y-Chromosome Analysis
Both the Western (R1b) and Eastern (R1a) Eurasian haplogroups are observed, although R1b is by far the more common. Haplogroup I is especially interesting since it may trace some of the Hunter GenoType migrations in response to the movement of the most recent glaciers, a point at which the Hunter and Explorer GenoTypes may have been one and the same.
DNA Mitochondrial Chromosome Analysis
Mitochondrial DNA tends to peg Hunter with the few ancient haplogroups and some of the more recent mutations. Most Hunters of African descent are part of the L2 haplogroup. Hunter is one of the few haplogroups that contains all three of the less common descendants of N: Groups I, W and X. Haplogroup I may have been among the very first to colonize Europe.
Other Western Haplogroups seen in Hunter are U and K. Haplogroup U is believed to have risen somewhere in Europe or the Near East approximately 55,000 years before present. Haplogroup K is a mostly Eurasian haplotype, and is believed to have first appeared when human populations expanded through Europe after the last glacial maximum in 16,000 BC. Mitochondrial H haplogroup is very common in European Hunters, but is also very common in other European genotypes as well. Mitochondrial haplogroup B may be an especially strong indicator in Hispanics and Polynesians.
The organs that govern our stress response are the adrenal and pituitary glands,
and, not surprisingly, these are vulnerable areas for most Hunters. Well-functioning
Hunters run on a healthy adrenaline high with short, sustained bursts of energy
that members of other GenoTypes often find astonishing. But good adrenal function
requires down time - periods when adrenaline is discharged through satisfying
physical exertion and when the mind returns to a place of calm. Hunters in our
modern world, with its perpetual deadlines and sedentary life, are all too prone
to adrenal burnout, the sad condition that results from excess adrenaline production
and insufficient stress release.
Hunters can also have difficulty properly adjusting what physiologists call the
'HPA Axis' the series of connections between the adrenal gland and the pituitary
and hypothalamus glands in the brain. The HPA Axis is responsible for regularizing
and normalizing the adaptive stress response, sometimes called the 'fight or
flight' reflex. Probably as a result of their optimization for hunter-gathering
with all its attendant risks and needs for present-time consciousness Hunters
would seem to wear a path out in the rug between their pituitary and adrenal
glands. Adrenal glands vary in weight from 7 to 20 grams in normal adults while
the thickness of the gland varied almost tenfold among individuals, and you can
bet that Hunters are at the top of the scale.
In the 1960's Henry Bieler, a medical doctor wrote a book called Food Is Your
Best Medicine. In it he described what he called 'Glandular Types' - differences
among people that are the result of one glandular system acting pre-eminently
over the others. Hunters would likely classify as 'Pituitary Dominant' in Bieler's
system; he describes the type as suffering from weak adrenal function, having
tall stature and a somewhat moody and perfectionist mental outlook. This is way
too broad of a brushstroke: Hunters display what more likely seems a highly developed
mechanical aptitude rather than any moody perfectionism.
An interesting feature of Hunter is that they almost always seem to be hungry,
yet often fill up quickly, with just a few bites of this or a sip of that. A
half hour later, it starts all over again. If you watch a few Hunters, you can
begin to see that this GenoType is hungry on a lot of levels; they love to tinker
with stuff and enjoy learning new things. However, like their appetite, they
often zoom right past it all in a desire to get to the end, or bottom, of things.
Before long, they’re on to something else.
Because of their reactive and inflammatory tendencies, Hunters can age rapidly.
Keeping a healthy dietary supply of proper gene promoting factors such as the
B vitamin Folic Acid is especially critical for optimizing gene methylation
(the process of maintaining DNA integrity during replication). Because of their
exposure to the various growth factors in early life, which can increase risks
for certain cancers, this is especially important to consider when supplementing.
Often the buildup of combinations of antigens and antibodies that come out of
solution in the blood and deposit in the tissues, called immune complexes, can
lead to autoimmune problems with the joints, kidneys and skin.
Hunters are prone to inflammation - the heat, redness, swelling, and pain that
result when the body fights off what it perceives as a dangerous invader. In
many cases, the cure is worse than the disease, since inflammation contributes
to numerous health problems, including arthritis, asthma, cancer, diabetes, and
heart disease. Inflammation may also contribute to obesity, so hyper-reactive
Hunters' price for not following their ideal diet is to, well, need a diet! As
you can see, an over-reactive immune system is the powerful Hunter's Achilles
heel, so the GenoType 1 Hunter diet is designed to get that immune system back
in balance and damp down its hair-trigger responses when they're not really needed.
Hunter has a somewhat hostile bent, and this can be tremendously amplified if
they are forced to derive intrauterine nourishment from a mother who is consuming
an inadequate amount of dietary fat or who is blood group A. The female Hunter
is a very effective genotype, with some wonderful predictives behind her. Curiously,
the spectrum of cancers that Hunters appear prone to seem to impact men a bit
more than women, especially those that involve hormone activation and the organs
of reproduction. In essence Hunter women are a bit more prone to malignancy,
but it is not malignancy that involves the breast, uterus or ovaries - the reproductive
organs. Male Hunters on the other hand do seem to have their fair share of prostate
The high water mark of hunter-gathering is often called the Mesolithic period ('Middle Stone Age') which began around 10,000 years ago and ended with the introduction of farming. The onset of farming differed from place to place, starting early in the Near East and much later in Europe. Hunter-gatherer technology reached its apex during the Mesolithic era; fishing tackle, stone adzes, canoes and bows have all been found preserved at various sites.
Popular culture tends to depict our Stone Age ancestors as crude, simplistic
animals perpetually at the point of starvation. "Solitary, poor, nasty, brutish
and short" as Thomas Hobbes had put it in 1651. Nothing could be farther from
the truth. Though small in number, Paleolithic hunter-gatherers worked far fewer
hours and enjoyed more leisure than typical members of industrial society, and
they still ate well, satisfied with very little in the material sense. The transition
from hunting and gathering to agriculture was not necessarily a one way process,
and evidence seems to disprove any notion that hunter-gatherers were saved from
extinction by the advent of farming technology. They seem to have been familiar
with farming practices when it arose, but for the longest time simply rejected
it or used it as a marginal supplement to the diet.
As these late hunter-gatherer societies evolved, they began to develop specializations such as fishing and seafood collection, harvesting nuts and fruits, or trapping small animals. They often had simple forms of representative government, based around family or clan.
Perhaps it is not coincidental that the story of the Garden of Eden in the Bible shares some of the same elements in its storyline. Some anthropologists have hypothesized that the Garden of Eden does not represent a geographical place, but rather represents cultural memory of the simpler times of hunter-gathering, when man lived off God's bounty, as opposed to being civilized and toiling at agriculture.
Because they typically function at such a high level of output, Hunter rarely sickens in an over-energetic fashion, rather more likely rapidly falling into one of any types of exhaustive states. In these circumstances they can have problems regulating their blood sugar, especially if they are deconditioned from a history of sedentary behavior. Earlier in life, with all their resources at peak function Hunter can develop a sort of free floating anxiety, occasioned by difficulties in their ability to clear adrenaline effectively from their bodies. These higher levels of adrenaline can often compromise their appetite and appreciation for the texture and flavor of food, and it is not uncommon for Hunters to complain during adolescence and early adulthood that they have difficulty keeping their weight up. If not effectively dealt with, this could easily devolve into anorexia and its associated eating disorders – a major problem with Hunter, since the muscle loss that occurs as a result of this difficult period can almost never be replenished.
Overcompensation was at one time a very effective survival strategy in the pre-antibiotic,
pre-vaccination days, but in our modern society with its abundance of new man-made,
xenobiotic chemicals, this type of reaction norm is as exhausting as it is unprofitable.
An exhausting it is: as Hunters age, their immune function can drop precipitously,
which along with their tendencies to longer lower leg length and its implications
with regard to childhood exposure to high levels of growth factors, goes a long
way to explain their surprisingly higher rates of malignancy. It’s also likely
that this tendency to malignancy is a result of epigenetic programming that needed
to anticipate maximum energy, fertility and strength during the 20's and early
30's but did not anticipate effectively the effects of the ongoing and steady
increases in lifespan that have occurred in the last several centuries.
The Hunter diet could be described as 'Pure Paleo' but that would not give this
GenoType adequate credit for the marvelous efficiencies by which they approach
and react to environmental challenges. By and large, if they can poke it with
a sharp stick, it's pretty much fair game for Hunter, though there is a difference
between their predictive goals - which are to survive long enough to reproduce
- and what most of us really want – the ability to survive a bit longer than
that. In order to accomplish that, Hunter must optimize their production of kinetic
energy, temper and balance their stress axis, and strive to control tendencies
towards runaway inflammation and pre-mature aging.
The GenoType 1 Hunter Diet is designed to help Hunters burn high-quality calories
while calming and soothing their hyper-reactive digestive and immune systems
(more about this in a moment). So just like that high-end sports car, which lasts
a lot longer if you give it high-octane gas, Hunters will see enormous benefits
in how they age if they eat right, get the right types of exercise, and use GenoSpecific
Hunter Activator is designed to offset the catabolic (cellular breakdown) tendencies that can cause many of the common health problems seen in the Hunter GenoType. These catabolic waste products are often the result of insufficient cellular detoxification (ubiquinylation), a common tendency in Hunters.
Hunter Activator Supplement Strategy:
Holy Basil: Holy Basil is regarded as one of the most important plants
used in Ayurvedic medicine. Over the past decade or so a number of
scientific studies have been made regarding this plant. Holy basil
may help counteract the effects of stress. Holy Basil supports healthy cortisol,
insulin metabolism, and blood sugar already in the normal range*
Turmeric/Curcumin: The active ingredients in Curcuma longa are a group
of plant substances called curcuminoids. Known collectively as "curcumin", curcuminoids
have demonstrated potent antioxidant properties in scientific studies. Curcuminoids
benefit joints and other tissues by helping to neutralize free-radicals. Through
its antioxidant mechanisms, curcumin supports colon health, exerts neuroprotective
activity, and helps maintain a healthy cardiovascular system.
Rhodiola: Rhodiola rosea has been categorized as an adaptogen by Russian researchers due to its observed ability to increase resistance to a variety of chemical, biological, and physical stressors. Rhodiola rosea appears to offer generalized resistance to physical, chemical, and biological stressors.

Hunter Catalyst is designed to provide maximum cell-integrity stabilization and to assist in the optimization of gut by enhancing cell repair and intracellular energy production.
Hunter Catalyst Strategy:
- Chinese Scute (Scutellaria biacalensis): Chinese Skullcap flavonoids
is a member of the mint family and has long been used in traditional Chinese
herbal medicine. Traditionally it has been used as a digestive aid and to normalize
an over-active digestive system. Scutellaria has been shown to decrease inflammatory
cytokine production from human mast cells (immune system hormones which ramp
up inflammation). Scutellaria also has a cell-regulating effect, encouraging
the body to more efficiently remove cells which have become dysfunctional, either
though age or malformation.
- Magnesium Butyrate: Butyrate is a short chain fatty acid that is a potent
detoxifier of ammonia and neurotoxins. It encourages the formation of friendly
bacteria in the gut. Butyrate is also one of the few dietary nutrients that has
an epigenetic (gene regulatory effect) due to its influence of DNA winding and
unwinding (histone acetylation and deacetylation).
- Arabinoglactan: Larch AG has been shown to increase short-chain fatty acids, decrease colonic ammonia levels, increase the numbers of beneficial bacteria in the colon, as well as improve the immune response. These favorable effects of Larch AG may positively modulate many of these too-common intestinal disorders.
- Bifidobacterium, Saccromyces and Lactobacillus Probiotics: These friendly
bacteria have positive effects upon the gut lining and help control bacteria
overgrowth. Saccromyces, actually a yeast, is a rich source of nucleotides (genetic
