I have heard of several times overs the years, stories of Asian females immigrating to the USA having much larger babies than their body can handle and require C-Sections for birthing children.

This was obvious due diet change from what normally ate and their bodies took advantage of it.

Actually c-sections are very common over here (Thailand) as well. My wife’s second child was a c-section baby as an example and this was 20 years ago. She was married to a Thai guy at the time, so you can’t account for Western genes accounting for it either.
