C elegans generation time

WebC. elegans offers several advantages for studying the basic biology of aging. First, the lifespan is relatively short (just 2-3 weeks under standard laboratory conditions), rendering whole-life survival analyses feasible. Second, large numbers of genetically identical animals can be easily grown under controlled environmental conditions. WebDec 11, 1998 · The application of the C. elegans project to the understanding of other animals, and of humans in particular, is compromised by the deep phyletic separation of the nematodes from other groups.
