So there may be a good evolutionary reason for r-type behaviours.
They do tend to have more children the earlier they hit puberty, BUT this isn’t good for the individual girl.
This paper examines the relationship between age at menarche and fertility from two perspectives. Age at menarche is regarded as a crude indicator of the timing of fecundity that may affect the timing of conception among those sexually active; and age at menarche is regarded as a crude indicator of the timing of sexual maturation that may influence the timing of socio‐sexual behavior, namely dating and sexual intercourse. The data are drawn from a survey of New York City women who recently had their first child. The findings suggest that age at menarche as an indicator of fecundity is not a good predictor of the timing of the first birth, when controlling for age at first sexual intercourse. Looking only at initial noncontraceptors, however, we find the relationship is stronger. Age at menarche, viewed as an indicator of the timing of sexual maturation, does seem to have some influence on the timing of dating, but only for Blacks. For both races, age at first date is related to age at first sexual intercourse.
Let your kids ‘date’, don’t act shocked when there are STDs and teenage pregnancies. If they’re so ‘mature’ they can live alone before doing that stuff. Paying for their own stuff.
While overall age of menarche doesn’t impact fertility or menopause, it can affect cancer or heart disease risk profiles, too premature or late, respectively.
In the mid-19th Century, the average age of menarche in the U.S. was around 17 years old (though given that slavery wasn’t outlawed until 1865, that data was not likely entirely representative). By 2002, it had dropped to 12.6 years old, according to the CDC, and by 2010, to 12.5 years old.
Telling little girls to masturbate in Sex Ed class (yes, they do) to ‘explore their bodies’ (orgasm) is probably triggering puberty in that system and menarche earlier, since the body assumes you’re having sex, also giving them a higher breast cancer risk. Thanks, feminism. You’re giving people cancer.
Androgens are triggered and depending on individual sensitivity, this can trigger premature puberty.
Telling little kids to masturbate is grooming in my opinion, and should be illegal.
In fact, pedophiles tell kids to do that, the rest is just context.
The worst behaviours of the worst r-types make total sense when you realize they don’t have morals, they want to access the children of Ks and turn them into their own kind.
The people all about sociology are suddenly blaming genetics when it comes to menarche? Anybody else find that odd?
As it is, women shouldn’t be having children before 20, it isn’t physically or psychologically good for us.
It is recommended that even if early marriages are preferred and adopted as cultural norms, they be discouraged to bear child before the age of 20 years.
But that’s actually good for women (and bad for r-types running Sexual ‘Health’ classes) so don’t expect to hear it.
Recommendations include encouragement of girls’ education, which has manyadvantages including the prospects of a better marriage, improved child-rearing, correctedrole of women in the community, financial rewards and improved standard of living for thefamily as well as delay of child bearing.
It’s better for society. (This includes men).
These data quite clearly highlight the need for effective measures for increasing the waiting time for motherhood after attaining puberty among females and these effective strategies should be implemented in the context of their socio-economic, cultural and demographic backgrounds.
