Facilitator Questions
Q. Why would mutations in the sensory system regulate aging? Could this be tied to the dauer pathway?
Q. One theory of aging is that longevity evolved as a trade-off for progeny production. If resources are limited, most of an organism’s energy/resources are invested in producing progeny, not in maintenance of older post-reproductive individuals. One extreme example is a salmon species that undergoes rapid aging immediately after spawning. What is implied by this theory? How does regulation of aging by the reproductive tissue in C. elegans argue against this?
