> Humans are extremely K-selected, ie it is optimal for us to spend a lot of resources on a small number of offspring human couples had children like clockwork year after year, but at least half of them died in childhood, with many mothers dying in childbirth, and with nursing motherhood as the only contraceptive. I don't think anybody was holding back as much as they were held back. And this continued up to the baby boom in the 20th century. Time to edit your myth.
