Women have started having children throughout the aeons at a very early age. It is onĺy in the last 80.000 years that humans have made the conscious connection between sex and having children. Womens fertilty declines sharply in their 30' and it is through conscious understanding of that fact and imitation that they think "their biological clock is ticking"; they consciously understand that it is now or never, that all their friends have children and that their looks and chances of attracting mates are fading. Also, I'm willing to bet that people in the "my biological clock was ticking" camp have much, much lower birth rates than average(probably close to 1), which is an indicator rhat they actually felt pressured not to be childless rather than a genuine desire to have childreN. I absolutely agree with your culture argument, I am just claiming that modern culture will go extinct unless we incorporate higher birthrates into it, not that the human species will go extinct.
