> and most notably the opening lecture from Charles Brenner had a great take-down on all of the reasons why longevity genes are unlikely to exist (TL/DR – genes only propagate if selected for, and there’s no selective pressure for longevity after reproductive age).
I mean, we don’t just drop dead the minute we pass reproductive age. One would expect there to be genes that affect aging (including past reproductive age), either due to different environments creating different selective pressures or just genetic drift or genes with an adaptive function for reproductive life having a side effect for post-reproductive life.
Consider particularly that women have a shorter reproductive window than men, but live longer on average.
