Senescence is error correction. We have babies and die instead of living forever and budding because 'compressing' an organism down to millions of gametes which are then 'decompressed' by growing new organisms from them is relatively pass/fail. If it works then you get a faithful copy. If it doesn't then the result typically gets recycled.
