Sir Michael Marmot to expand the Whitehall Study to look at why we “age” differently

Marmot’s Whitehall Study is a longitudinal study that has studied the effects of social status on health. He used as his sample a large number of well educated British Civil Servants – Hence “Whitehall”. A key finding has been the … Continue reading

Thesis 26

Thesis #26 – The forces of natural selection can be strengthened during adulthood by postponing the first age at which they begin to decline, which can be achieved for the force of natural selection acting on age-specific mortality by postponing … Continue reading

Thesis 27

Thesis #27 – Among populations which have had their forces of natural selection strengthened experimentally, detectable improvements in adult survival and reproduction have been observably achieved within dozens of generations. So there I am, in 1977, realizing that all evolution … Continue reading

Thesis 28

Thesis #28 – Among such experimental populations evolving greater levels of adaptation at later adult ages, evolutionary changes in (a) structural gene frequency, (b) gene regulation, (c) patterns of cumulative damage, and (d) still other features of physiological function will … Continue reading

Thesis 29

Thesis #29 – Species with fully symmetrical fission as the sole means of reproduction do not have a declining force of natural selection acting on survival, and they do not evolve aging phases in which all individuals show declining survival. … Continue reading

Thesis 30

Thesis #30 – The forces of natural selection plateau at zero values at very late adult ages, and do not decline further for all subsequent ages. This is the most important thing of all, even if no one understood what … Continue reading
