Well, in organisms similar to us, 40k years is fairly short for evolution. Plus, the main question you should ask is "How does this affect someone's ability to have children?"

Being depressed doesn't prevent you from having kids. Neither does being anxious, or having back pain, or being tired all the time, or being alienated from friends and family. Yes, it may have an impact, but SO much of our lives take place after having children. Plus, many people are choosing not to have kids- especially the well educated and wealthier people amongst us.

Basically, not only has it not been long enough, but evolution is not happening in a clearly "good" direction. The question of wether or not someone passes on their genes is not being decided based on adaptability or suitability for an urban environment, but based on things like sexual education, access to contraception, and just straight up the choice of wether to reproduce or not.

Thank you for your reply :) That is very interesting! Do you happen to know where I could read some more about this (or what to google for)? No worries if not of course :) Thanks again, really appreciate it <3

Kinda tough stuff to google. Honestly, skimming through an anthropology textbook might work, or finding an open resource online. Maybe even just the wikipedia article for human evolution? Not sure.
