@TrevorGoodchild I thought this determined when they had their first child but this is just the age of parents determined by genetic mutation and averaged, so this says almost nothing about the mating habits unless I can find the distribution somewhere

@WandererUber Yeah I need to find the dataset. But it makes a bit of sense with late menarche due to nutrition (calories haven't always been easy to come by)
@TrevorGoodchild reading the paper rn and for some fucking reason they used AI. what the fuck dude
>Data on de novo mutations from 1247 Icelandic trios (14) were used to train a model that predicts the effect of both maternal and paternal age on the mutation spectrum.
they could have literally just done a bit of statistics instead... Why did they introduce randomness. are they stupid?

@TrevorGoodchild I'm a little rusty on how biologists do things but is THIS the confidence interval? Three+ years?
This makes the dataset a bit useless, no?
Again, rusty, but doesn't that mean basically any person from the dataset could potentially have been born to parents three to five years younger (or older), AND they don't even know who's siblings, whos the firstborn, etc...
Then the only thing this entire study tells us is that the average male-female gap was about 7 years...

@TrevorGoodchild @WandererUber Births to juvenile females tend to have high mortality rates due to lack of maternal resources and lack of maternal experience. You‘ll find the same pattern in other primate species and other mammals more generally.
@AuntNorma @WandererUber The sweet spot seems to be the female 20s. Earlier has a complication rate, likely due to unfinished physical development. After 30 the fertility dive kicks in. 35+ is geriatric pregnancy.
@TrevorGoodchild @AuntNorma the problem is this study doesn't help much in proving that.
People keep saying what you're saying and it's probably reasonable.
But we can't really prove it without human experimentation or more historical data.
You could also easily make a case that pre-agricultural humans accumulated a lot of damage once they hit adulthood, meaning a woman in her 20s would have other disadvantages in pregnancy.
And
>unfinished physical development
is still really hard to estimate too just because white girls in industrial society mature later and malnourished girls also do, that's hardly a full picture
