It is Challenging to Find Support for Evolutionary Trade-offs Between Reproduction and Aging in Human Data

The disposibility theory of aging is one of numerous evolutionary theories of aging that seek to explain why aging exists and is near universal across species. In this case, aging is viewed as the inevitable result of trade-offs between resources allocated to reproduction versus resources allocated to tissue maintenance. Like near all evolutionary theories, and particularly those relating to aging, the models and the science are much debated.

Since there is some variation between individuals within a species, one should expect to find a distribution of outcomes for any given trade-off when comparing large numbers of individuals of a given species. In this case, for this view of the origin of aging, we should expect to see that greater reproductive success correlates with a worse outcome in later life. Meaning a faster decline, mo…
