Why do we age? Why do we age?
Summary: Why do we age? Scientists respond to the question by presenting the latest evolutionary theory on aging: the disposable soma hypothesis, which supports the benefits of calorie reduction in terms of longevity. Tom Kirkwood, a leading geroscientist provides commentary. This article was originally published on LongevityFacts.com. Brady Hartman is the author.
People who adhere to Darwin’s theory on evolution may find it difficult to accept the idea of growing older. The vulnerability of an organism increases with age, and this ultimately leads to death. How could evolution be favored by a process which gradually increases mortality while decreasing the ability to reproduce.
Scientists have proposed a new theory to explain this paradoxical contradiction. They suggest that ageing confers an evolutionary benefit.
