We live in a world in which near all species exhibit degenerative aging, yet some few species exhibit negligible aging until very late life, and a very much smaller number of species appear not to age at all. Aging isn’t inevitable, yet it is near universal. Why has evolution produced this outcome? While there is a consensus answer to this question centered around the concept of antagonistic pleiotropy, the evolution of aging is a field of research characterized by continual debate, an ever changing sea of novel ideas that come and go from year to year. In part this is because it is challenging to prove any given theory definitively right or definitively wrong, but also in part because we live in an age of biotechnology, in the midst of a flood of new data on the biochemistry of aging, any piece of which might be argued to change the bigg…
