So when will you lose your health – Part 2 – When you live in the wrong environment

You get ill when you look like this – this is how I looked aged 59 – I weighed 205 lbs. How I look here has all the signs that you have not lived your life according to the rules. … Continue reading

Why are we so fat in rural settings? – Part 3 – Our Ancestry!

Prince Edward Island, where I live, has a very high obesity rate. So do many rural parts of America and of cource the rest of Atlantic Canada. We have looked at why there is an physical environmental difference between cities and … Continue reading

Diet – What you need to know based on your heritage

Thesis 50 reminds us that if you are a person with a heritage that is adapted to the agricultural diet – say from Western Europe – then you can do quite well on the Agricultural diet for a while. 30 … Continue reading

Aging – What is it and why you can avoid it’s ravages

What is aging? Is the deterioration we see inevitable? Are the diseases that come with age all part of the process? Is it inevitable that we get sick and decrepit as we get older? On the surface it looks as … Continue reading

Thesis 31

Thesis #31 – After the forces of natural selection plateau, it is possible for survival and reproduction to plateau at positive values due to age-independent beneficial effects of some genetic variants. As with modern physics, again, it is often difficult … Continue reading

Thesis 32

Thesis #32 – Before the forces of natural selection plateau, it is possible for genetic drift, due to small population sizes among other possibilities, to weaken the ability of natural selection to distinguish among genetic variants affecting later adult life, … Continue reading

Thesis 33

Thesis #33 – When late-adult plateaus in survival and reproduction occur, members of biological cohorts that reach such plateaus will show stabilization of some but not necessarily all functional characters. Evolutionary theory makes a simple prediction about how the key … Continue reading

Thesis 35

Thesis #35 – The ages at which the forces of natural selection plateau depend on the last ages of reproduction and survival in the evolutionary history of a population, allowing experimental evolution of the cessation of aging by deliberately changing … Continue reading

Thesis 37

Thesis #37 – Patterns of aging, including the rates of decline of functional characters and the timing of any cessation in such decline, depend on the environments in which cohorts are raised and live as adults. (Picture of Einstein talking … Continue reading

Thesis 45

Thesis #45 – Our ancestral hunter-gatherer populations had generally low population densities, and thus low effective population sizes, which produced relatively early cessation of aging at relatively high function due to genetic drift. With very low population densities among our … Continue reading

Thesis 46

Thesis #46 – In the last ten to twenty thousand years, some human populations adopted extensive agricultural cultivation of grass species and the use of milk from other mammals for nutrition, a novel environment which changed the action of natural … Continue reading

Thesis 48

Thesis #48 – Agricultural populations have also undergone substantial increases in population size compared to those of their ancestral hunter-gatherer populations, which increased the effectiveness of natural selection at later adult ages, resulting in the evolution of a delay in … Continue reading

Thesis 49

Thesis #49 – In agricultural populations over the last ten thousand years, the longer-sustained effectiveness of natural selection has resulted in an age-dependent pattern of falling adaptation to agricultural conditions in which functional decline is sustained over a longer period … Continue reading

Thesis 50

Thesis #50 – Children and young adults with predominantly agricultural ancestry are well adapted to agricultural conditions of nutrition and activity, but children and young adults without agricultural ancestry are not adapted to such conditions. Let us address with particular … Continue reading

Thesis 51

Thesis #51 – Older adults from all human populations are not adequately adapted to agricultural patterns of nutrition and activity, resulting in an amplification of aging under such conditions. Naturally, older adults from non-agricultural populations will be no better adapted … Continue reading

Thesis 52

Thesis #52 – All people without significant agricultural ancestry should revert to patterns of nutrition and activity which have physiological effects like those of hunter-gatherer lifestyles, in order to slow their aging and hasten its cessation. The case of individuals … Continue reading

Thesis 53

Thesis #53 – Young people with significant agricultural ancestry can sustain their health with agricultural patterns of nutrition and activity, but not with an evolutionarily novel industrial lifestyle. It is tempting to suppose that young people with agricultural ancestry are … Continue reading

Thesis 54

Thesis #54 – Older adults with significant agricultural ancestry cannot sustain their health with either agricultural or industrial patterns of nutrition and activity, and should instead switch to hunter-gatherer patterns of nutrition and activity in order to slow their later … Continue reading

Thesis 55

Thesis #55 – Once this switch to a hunter-gatherer lifestyle among older adults has become widespread, further changes that would enhance human health at later ages can be discovered using evolutionary research tools, such as experimental evolution with model organisms … Continue reading
