I have been said to overthink reproduction, but in my view it takes a central place in the HG hypothesis. Using life-history theory, I distinguish three types that are slightly shifted in their life history with hunter-gatherers- n-types included - the most K-selected and pastoralis -sp types - the most r-selected. sj or farmer types in the middle. That means also the s-types start puberty a bit earlier and become more likely sexually active earlier on with sj likely to marry their high school sweethearts. the socially assigned roles of man the breadwinner and women responsible for domestic chores was likely a farmer innovation too, and I guess n-women are therefore more likely prone to postpartum depression and the least likely to have a whish to become mothers when hunter-gatherers practise allomothering - around. 60 per cent of neurodiverse mosthers suffer from ppd vs the 10 per cent in the general population this model would also explain why neurodiverse people often have older fathers. This pattern would also explain why n-types have a particularly hard time getting accepted during their teenage years. finally it woul explain the distribution of common s types and rare n types we see.
