This group somehow links it to natural selection:
A new USC Dornsife study indicates that aging may have originated at the very beginning of the evolution of life, at the same time as the evolution of the first genes.
This could be a game changer for research on longevity and aging. It may also be relevant to the scientific discussions surrounding CRISPR9 gene editing,” said John Tower, biologist at the USC Dornsife College of Letters, Arts and Sciences. “We found that when it comes to genes, aging may not always be a negative trait. It may help an organism survive.”
To test this, Tower and a team of researchers developed a scenario with molecules can replicate themselves. Such molecules are believed to be the evolutionary origin of modern genes.
Using computer modeling, the researchers paired an unstable short-lived gene, B, and its interactions with a longer-living gene, A, to create a new replicator, AB. In some simulations, the fact that B was short-lived enhanced beneficial aspects of A that would maximize the proliferation of the AB replicator.
“The results suggest that evolution can favor the limited stability of genes as a way to increase complexity and the reproductive fitness of the organism,” Tower said. University of Southern California, “Aging may be as old as life itself” at Eurekalert
Sounds pretty thin considering that, due to entropy alone, things wear down, whether that makes them more fit or not. But the research is of interest to the booming anti-aging market and, for sure, that market wants to believe.
