Summary
A new perspective in Aging argues that aging is not mainly passive wear and tear but a side effect of biological growth and developmental programs that continue after their useful phase ends.
João Pedro de Magalhães says this hyperfunction view better fits evidence such as lifespan gains from single-gene changes, reduced growth hormone and IGF-1 signaling in mice, rapamycin, and caloric restriction.
The paper ties the idea to older concepts including antagonistic pleiotropy and Mikhail Blagosklonny’s “quasi-programs,” while still acknowledging molecular damage contributes to cancer and likely interacts with programmatic aging.
Future tests will focus on developmental biology and partial cellular reprogramming, which resets gene regulation; if that restores function, de Magalhães says it would challenge purely damage-based models.
He cautions the theory still needs rigorous experimental validation in humans and a clearer molecular mechanism, with aging likely shaped by both developmental programs and accumulated damage.
