What is "phenoptosis"

Phenoptosis (pheno - showing or demonstrating, ptosis - programmed death), designated by V.P. Skulachev in 1999, signifies the phenomenon of programmed death of an organism, i.e. that an organism's genes include features that under certain circumstances will cause the organism to rapidly degenerate and die off. Recently this has been referred to as “fast phenoptosis” as aging is being explored as “slow phenoptosis.” Phenoptosis is a common feature of living species, whose ramifications for humans is still being explored.
