Longo’s research is mainly based on observation of programmed aging in yeast. Scientists have used yeasts because molecular pathway that regulates its longevity is similar to other more complex organisms like mice and possibly humans.
The results of this research are surprising. Yeasts, which were studied died well before they were supposed to in order to provide nutrients for those yeasts within that same population which have acquired genetic mutations. In short, many millions of yeasts died early to suit few better-adapted mutant yeasts. Can this process happen in humans as well?
“If aging is programmed in yeast and latter’s molecular pathway is very similar to human’s, then isn’t it possible that humans also die earlier than they have to?” said Valter Longo.
Apart from possibility that we might have been wrong in sticking with Darwin’s all-too-known theory for so long-provided Longo’s theory is proven to be correct- gerontologists (scientists studying aging process) are now conjecturing that aging may actually be healed.
It seems easier to tweak programming in a computer than to try to replace part after part in an old car that is steadily collapsing.
For Valter Longo, most organisms undergo programmed longevity. Is life therefore supposed to be programmed?
