How did ancient people figure out that sex leads to kids, since the effects are so delayed?
But that seems like quite a delayed reaction. It could have taken a long time for ancient humans to connect the dots and realize that sex caused pregnancy.
Yes, that is a valid point. Some researchers have suggested that early humans may have made the connection between sex and pregnancy faster by noticing the relationship between female menstrual cycles and pregnancy.
