Scientific paper

Well protected human and laboratory animal populations with abundant resources are evolutionary unprecedented. Physical approach, which takes advantage of their extensively quantified mortality, establishes that its dominant fraction yields the exact law, whose universality from yeast to humans is unprecedented, and suggests its unusual mechanism. Singularities of the law demonstrate new kind of stepwise adaptation. The law proves that universal mortality is an evolutionary byproduct, which at any age is reversible, independent of previous life history, and may be disposable. Recent experiments verify these predictions. Life expectancy may be extended, arguably to immortality, by relatively small and universal biological amendments in the animals. Indeed, it doubled with improving conditions in humans; increased 2.4-fold with genotype change in Drosophila, and 6-fold (to 430 years in human terms), with no apparent loss in health and vitality, in nematodes with a small number of perturbed genes and tissues. The law suggests a physical mechanism of the universal mortality and its regulation.
