MTOR-driven quasi-programmed aging as a disposable soma theory
If life were created by intelligent design, we would indeed age from accumulation of molecular damage. Repair is costly and limited by energetic resources, and we would allocate resources rationally. But, albeit elegant, this design is fictional. Instead, nature blindly selects for short-term benefits of robust developmental growth. "Quasi-programmed" by the blind watchmaker, aging is a wastefu...

15 صفحه اولThe Germ-soma Conflict Theory of Aging and Death: Obituary to the "Evolutionary Theories of Aging"
Regarding aging, the scientific community persists in a state of collective schizophrenia. This state is owed to the so-called “evolutionary theories of aging”. According to these theories, aging, following the peri-/postreproductive decline of selection pressure, is posited to be haphazard, not selected for, not adaptive, and not programmed. And yet, defying these concepts, aging is phylogenet...
متن کاملThe heat dissipation limit theory and evolution of life histories in endotherms--time to dispose of the disposable soma theory?
A major factor influencing life-history strategies of endotherms is body size. Larger endotherms live longer, develop more slowly, breed later and less frequently, and have fewer offspring per attempt at breeding. The classical evolutionary explanation for this pattern is that smaller animals experience greater extrinsic mortality, which favors early reproduction at high intensity. This leads t...
