Would it be fair to say that a conclusion you could draw from the data you outlined here would be that people currently in ketosis would fair better at higher altitudes?

Sorry if I'm misunderstanding this, this is very far from my area of expertise.

I found an apple tree on an island in the middle of a lake once, while out kayaking. It had apparently been there for quite some time, completely untended to by human hands. I was excited to try a "natural" apple, for whatever reason I had the idea that it would be tastier than store bought apples. I regretted biting into it pretty much immediately. It was my first lesson on the importance of artificial selection in the palatability of our produce.

I have found out, since then, that apples grown for their edibility are grown from grafts, not seeds. Most likely, someone at some point stopped on that island and had lunch, and left apple seeds on the island, which eventually grew into a wild apple tree. Wild apples aren't edible, and the apples we know and love have been carefully bred to be the way they are.
