Asking from an evolutionary viewpoint.

Sex is a pleasure giving activity so that it encourages reproduction and spreading of genes. But childbirth ,the most crucial part of the reproductive process, is equally opposite and many times hazardous to the health or even fatal to the mother.

why is that so? Not enough selection pressure (low death rate than succesful delivery rate)?

  • $\begingroup$ It's definitely not an adaptive trait to feel pain when giving birth - your nerves as electrical alarms don't care what is the cause of the pain you need. This has nothing to do with the fact that giving birth can be fatal to the mother. Apart from that, reproducing is the most important life function from the evolutionary perspective. $\endgroup$ – Probably Jun 24 '16 at 5:35
  • $\begingroup$ @probably yes but what i meant is why giving birth causes potential trauma and suffering to human body? $\endgroup$ – user1062760 Jun 24 '16 at 8:06
  • $\begingroup$ Nerves are electrical alarms for any type of damage. How would they recognize the pain comes from actually a useful thing? $\endgroup$ – Probably Jun 24 '16 at 11:06
  • $\begingroup$ What I'm trying to say is why birthing is not evolved to a level where it's no longer damaging and potentially fatal to the mother $\endgroup$ – user1062760 Jun 24 '16 at 16:11
