Thesis 12

Thesis #12 – Aging is a pattern of declining or de-tuned adaptation that is correlated with adult age only because adult age is at first strongly correlated with declining forces of natural selection. We have all seen sunrise and sunset.  … Continue reading

Thesis 13

Thesis #13 – The declining forces of natural selection lead to an evolutionary failure to establish the genomic information required for tuning the complex networks of life well enough to provide a high level of health indefinitely; there is no … 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

Thesis 17

Thesis #17 – When such trade-offs arise from antagonistic pleiotropic effects of genetic variants, they sometimes maintain genetic variation for functional characters, and thus selectable genetic variation for patterns of aging. There are two kinds of trade-off which are important to … Continue reading

Thesis 18

Thesis #18 – When such trade-offs can be physiologically tuned within the lives of individual organisms, natural selection may act to produce physiological machinery that provides plasticity which enhances average fitness. One of the basic features of natural selection is its … Continue reading

Thesis 19

Thesis #19 – Such adaptive life-history plasticity will sometimes produce detectable trade-offs between survival and reproduction in the range of environmental conditions that prevailed when natural selection established such life-history plasticity. It is a general, though not universal, rule that, if … Continue reading
