Decay Quote by Richard Dawkins
““senile decay is simply a by-product of the accumulation in the gene pool of late-acting lethal and semi-lethal genes, which have been allowed to slip through the net of natural selection simply because they are late-acting.””
About This Quote
Source Book: The Selfish Gene, Richard Dawkins, 1976
Late‑acting harmful genes persist because natural selection acts mainly before reproduction, so they accumulate and cause senile decay.
In simple terms: Late‑acting genes survive selection, causing aging.
Consider how evolutionary trade‑offs affect health.
