At the individual and immediate progeny level, aging doesn't affect generation time. If there were group selection it might, as the older people displace resources for the younger, but for an individual that should be dilluted down to no real effect.
- atticora 3y agoSince a given niche can only support a given population size, aging reduces generation time by hitting a ceiling on population size. Some organisms get around this by spawning thousands of offspring and all but approximately one fails fast. So that's an available trade-off. Increase individual age limits, but maintain adaptation rates by letting many immature individuals compete and die before maturity. Like spermatozoa and tadpoles.
