You must die. It's math.

Aging seems to be an inevitable fact of life, at least ours, and yet this global cell disaster has not prevented all mankind from pursuing the dream of immortality. Well, that's why the myths of the source of eternal youth or life expectancy, but above all, this is the reason for the strategic profits of companies that sell <x0) regenerative heads, or those that promise to keep the dead or parts of them at very low temperatures, waiting for science to find a cure for the causes of their deaths.

Marvelous waters, creams, extreme cold until now, everything has been in vain. While if that wasn't enough, now a mathematical demonstration explains why this is simply impossible.

EV O HAPPION KONON TIME: NO

Evolutionary biologists have begun to extinguish the hope of everlasting life (on this earth, at least) with two fundamental scientific principles: the shadow of selection and changes in gene action, youth, and old age. The promise of all discussions is surprisingly simple:

The ultimate purpose of evolution is to select individuals who have been better reproduced than others, meaning those who leave more offspring

The shadow of selection identifies the stage in which natural selection no longer operates on mutations that occur in old age when individuals have reproduced. Although the natural mutations of DNA are negative, in fact, they do not influence the descendants of the individual, who has already been born: therefore, they are no longer the object of interest “of natural selection and are not blocked.

The various actions of genes in various stages of life are a phenomenon called antagonistic pleitropia: what happens is that if some genes have a positive effect on the youth (and thus increase the reproductive success) natural selection tends to preserve them.

And if the same genes have a negative effect on old age... bad for the elderly, who find themselves in pieces DNA from the opposite action.

Math of Death

These were the premieres, plus a mathematical demonstration administered by two researchers at the University of Arizona's ecology department, as well as the department of evolutionary biology. Researchers note that cells in multicellular organisms must cooperate to keep the entire body alive: In doing so, some cells may be eliminated because they do not reproduce more, fail to repair any damage, and therefore are no longer functional.

Among those who have reproduced there are some that, based on mutations that always occur when cells are separated, are not “part” of this co-operation: they breed uncontrolledly and can become carcinogenic.

By building a mathematical pattern of cell populations, the two researchers have shown that cells are subject to one of two sad destinies - lack of functionality, or uncontrolled growth. The first die because of age, the second causes the body to die from tumors or other diseases. Output: Equations show that death is inevitable for multicellular organisms like us. / Focus 'world.al
