Diet – Where your ancestral heritage is important

Surely we must have adapted to agriculture by now? The answer is no and sort of yes to that question. It depends on what your ancestral heritage is or how long you have been exposed to agriculture. Let’s take dairy. … Continue reading

Talking about Environments – What about your mouth?

Ideally our mouths should be on the alkaline side. Before the modern diet, they were. Before the modern diet there was next to no caries. Today we brush our teeth to give us a chance of beating caries. But what … Continue reading

Thesis # 2

Thesis #2 – Natural selection reliably produces high levels of biological fitness, and thus good health, only under the environmental conditions in which it has been acting for many generations. A common caricature of evolution by natural selection is that … Continue reading

Thesis # 3

Thesis #3. Health and adaptation thus reflect the action of natural selection on a population in its previous environments, not its present environment, when these differ. For the purpose of re-founding medicine scientifically, theses 2 and 3 direct us to … Continue reading

Thesis #4

Thesis #4 Natural selection results in the evolution of good health only when there is sufficient heritable variation affecting survival and reproduction. Natural selection accomplishes nothing without an adequate and appropriate supply of genetic variation on which to act.  That … Continue reading

Thesis 14

Thesis # 14 – Aging hypotheses based solely on supposed universal imperfections of molecular, cell, or organismal physiology are wholly falsified by the existence of biological species that do not exhibit falling average rates of survival and reproduction among large cohorts … Continue reading

Thesis 15

Thesis # 15 – Aging evolves because of the previously adduced evolutionary genetic limitations to the forces of natural selection, which are affected by physiology, but aging is nonetheless not a merely physiological process.  Do the last five theses imply that … Continue reading
