Aging in Sponges,volutionary earliest living relicts of the successful transition from the (perhaps) unicellular to the multicellular state . Evidence has been presented by molecular phylogenetic analysis that sponges share a common ancestor with the other metazoan phyla, the hypothetical Urmetazoa .

Aging and Environmental Conditions in Insects,ow is remarkably low. In spite of the existence of about 1.2 million insect species not more than about 50 species were listed for their mean life-span in the classical report of Rockstein on insect aging in the seventies . The situation does not have fundamentally changed since that time. A summ

Genetics of Aging in , ,ents have led a two-pronged attack: one at the level of single-gene intervention and a second at the level of whole genome analysis. More than ten years elapsed between verification that the rate of aging was heritable in flies and discovery of the first single mutant that extended lifespan .

Aging in ,,nematode . (.). We owe much of our general view of the genetic determination of lifespan to this organism. . became a popular organism for the analysis of complex biological problems following the pioneering work of Sidney Brenner and Sir John Sulston who determined the developmental cellular fate m
