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 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 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 38

Thesis #38 – Some environmentally-induced variation in patterns of aging reflects the impact of selectively-favored patterns of life-history plasticity, but some environmental variation in aging does not reflect adaptive plasticity, such as that due to novel environments. An important distinction … Continue reading

Thesis 41

Thesis #41 – Experimental strategies for the study of aging that involve the use of environments that are evolutionarily novel will systematically impair the scientific study of aging, as natural selection will not have previously fostered adaptation to such novel … 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
