I'm curious what you mean. Are you implying that people are deliberately killing off certain segments of the population? If so, we mustn't allow them to avoid blame by citing evolution.
I'd disagree on post partum depression. The body gradually increases feel good/painkilling neurotransmitters during pregnancy, so when the mother goes into labour she is naturally high enough to deal with the pain of child birth. Then the body goes back to normal levels of those neurotransmitters, which feels like withdrawal.
This is not an example of natural selection.
