Science proves jailbait is the best.

define 'reproductive value'

Reproductive value (RV) is basically a measure of the amount of offspring a female of a given age can be expected to have over the remainder of her life. By mathematical definition this rises with age up to the beginning of a female's reproductive lifespan, as the probability of her dying before she starts reproducing decreases, and then goes into decline as she uses up her fertile years.

The values in the graph were taken from Amazonian populations which make fairly good models of prehistoric people. In these populations the average age of a girl's first pregnancy is about 17 which explains why the graph line peaks there. The best age for a man to acquire a girl as a wife would be just before that as she approaches the beginning of her reproductive lifespan. Obviously a man needs to acquire a girl before the peak and not after it when she's already started reproducing with another man in the tribe.

Maybe this is the reason girls grow eye-catching perky boobs at this age. They signal that she's approaching reproductive age.

Is that what you masturbate to? That's actually boring

Those boobs tho

Any biologist here can confirm this?

>>8523191
I'm no biologist and not op, but I imagine it's tied to things like the health of the offspring. Consider how older women are more likely to produce offspring with several problems, ranging from autism spectrum tendencies to stillbirths

"science"
more like
"we looked at amazonian and african tribes as those were the closest humans were to a 'natural' state and hurrr, all so young"

they also found optimal marriage relation is cousins in the same population. hurr.
