FTFY
In the wild.. Humans have been estimated to die around age 40.
So, assuming naturally that the female would've lived long enough to raise her child, she would require at least a 5 year window to rear a somewhat independent offspring.
40-5 = 35, that means at the latest, natural evolution would've placed the final deadline for progenation at ~ age 35..
and we also see that the probability for miscarriage and other complications rise dramatically beyond this age.. which supports the evolutionary pinpointing.
Now, modern medicine can overcome many of these hurdles for late moms.
However, it does not change the hard fact that the equipment only operates at peak efficiency for a short number of years.
Which is why youth is the most important currency, especially for females..
