It would be interesting to watch several hundred generations of offspring
of flies with disabled INDY gene, subjected to various sorts of stress--for
example exposure to carcinogens and shortages of food. Also interesting to
follow generations of offspring produced during latter portion of extended
lifespan.
Also would be interesting to compare populations of calorie-restricted
animals (flies or whatever) with populations of animals with disabled INDY
gene.
