Why can really bad odors induce vomit?
In: 345
People who did *not* have a tendency to vomit from really bad odors would’ve been more likely to eat bad food and get sick, which means they would’ve been less likely to survive long enough to have children.
Fast forward a couple hundred thousand years, and you are the descendant of the people who *were* more sensitive to bad smells, and you’ve inherited rhat survival mechanism – even if it goes unfortunately overboard sometimes.
