You can even chart this with birth and marriage data gathered in the 1930s onward. 70% of Marriges had a child born in less than 6 months after the marriage papers. ie 3/4ths of all humans were fucking hard and the remaining 1/4th would panic settle to not be alone. We mastered birth control and keeping people distracted and this is the result: half of men and women between the ages of 24 and 40 are single and without child.
This is most of modern problems by the way, we solve for something that we saw as a bug when it was the feature of our existence.
