“The long-term consequence of such effects is an expected genetic deterioration in the baseline human condition, potentially measurable on the timescale of a few generations in westernized societies, and because the brain is a particularly large mutational target, this is of particular concern.” The word is dysgenic for $200.
“Ultimately, the price will have to be covered by further investment in various forms of medical intervention.”
Good luck with dropping global IQ, if anyone dared measure such a thing. Sum IQ/global population is the equation.
Who will pay for this global NHS? Our NHS is already running down with a slight immigrant pressure.
It is slight compared to The World.
As JF has mentioned, “clusters” as seen in racial categorization, pertain to findings of genetic distance.
Examination of the relationship between genetic and geographic distance supports a view in which the clusters arise not as an artifact of the sampling scheme, but from small discontinuous jumps in genetic distance for most population pairs on opposite sides of geographic barriers, in comparison with genetic distance for pairs on the same side.
Speaking of germline mutations ruining society.
Older fathers’ children have lower evolutionary fitness across four centuries and in four populations
Is that a large enough sample for the manosphere? They don’t like the answer so obviously not.
As if I don’t post topics strategically… tut tut.
“Higher paternal age at offspring conception increases de novo genetic mutations. Based on evolutionary genetic theory we predicted older fathers’ children, all else equal, would be less likely to survive and reproduce, i.e. have lower fitness.”
The sins of the father…
Old dads, no grandkids?
“showed negative paternal age effects on infant survival and offspring reproductive success.”
Sexual selection goes for young men, with better hormone profiles and less obesity.*
Darwin says aged paternal societies are bad for it. Nobody needs your dusty DNA. That’s a sign of corruption – keeping the young men down, not breeding. *another direct link to children again
“Effects survived tests for key competing explanations, including maternal age and parental loss,”
Again, you cannot blame the women.
“We can use our findings to aid in predicting the effect increasingly older parents in today’s society will have on their children’s survival and reproductive success. To the extent that we succeeded in isolating a mutation-driven effect of paternal age, our results can be understood to show that de novo mutations reduce offspring fitness across populations and time periods.”
As close as science gets to settled.
Old fathers are a sign of a dying society. Right up there with strippers and crossdressers. You passed the time period where you were viable with decadence but managed to breed anyway, that society’s social norms are seriously damaged. Applies to women too but paternal age is a bigger factor so I have to spotlight. In a Patriarchy, you would expect fathers are held to the highest standards possible. Their total authority relies on the moral authority consequent of that fact.
