Yes. One example of evolution happening even as a result of cultural differences: In Europe and Africa, people have learnt to brew alcoholic drinks to make their water safe from bacterial contamination.
People who couldn’t stomach alcohol were more at risk of getting sick from contaminated water, so there was an evolutionary push towards alcohol tolerance.
People in Asia have boiled the water to make tea instead, for the same reason. They didn’t have this evolutionary pressure, which is the reason Asians on average have a lower alcohol tolerance even today.

My wife is Asian, and she will get very nauseous or even throw up before she will get buzzed.
