Do you ever think about the reasons it’s so hard to engineer foods that reliably imitate high-calorie sources is because there’s no such thing as taste, your body is using chemical sensors evolved for hundreds of millions of years to directly identify high-priority nutrients.

I think about this all the time

Then again, the body triggers the hypercapnic response based on high carbon dioxide levels instead of directly measuring blood oxygenation, so your mileage may vary in how successful evolution actually is towards ideal clean-room implementation of survival processes.

Would that not be a case of detecting high carbon dioxide?

If you put a burrowing animal in a pure nitrogen atmosphere, it will panic and try to flee. A human being will pass out and die with no distress

Oh wow. Interesting. Do they encounter high nitrogen environments underground?

The point is low oxygen is a separate thing from high CO2, and they detect both, since both kinds are prevalent underground. This paper goes into some of the weeds on life underground: https://repositorio.uc.cl/bitstream/handle/11534/13023/Comparative%20respiratory%20strategies%20of%20subterranean%20and%20fossorial%20octodontid%20rodents%20to%20cope%20with%20hypoxic%20and%20hypercapnic.pdf?sequence=1 …
