Today's lectures spanned subcellular level to ecosystems. After today I find myself increasingly in exploring whether and how well conceiving of aging as a narrowing of the range of dynamic responses to environmental change works 'below' the organismic level.
Tomorrow we will define aging---it will be important to separate what are 'wear/tear' effects (calcification, fibrosis etc etc. etc.), what are from longevity issues.
Is there underrecognition of the role of induced developmental pathways during pre-scenescent periods on characteristics of senescence
What is and is not sound about the hypothesis that for older animals with decreasing reproductive ability, engaging in activities which improve safety and resources of the environment (which would give their preexisting offspring advantage) might induce life-extending effects. Selection for longevity potential....amplified by induction of pathways by environment/community enhancing activity.
