Thesis 44

Thesis #44 – Most of our ancestral hominin populations of the last million years benefited from increased forces of natural selection at early adult ages under conditions of relatively abundant nutrition derived from hunting, gathering, and cooking and an increased … 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 47

Thesis #47 – This novel agricultural lifestyle initially depressed adaptation and health, leading to intense natural selection for adaptations to the digestion of foods derived from grasses and milk, which has since produced adaptation to agricultural conditions at early ages. … 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
