a population in one environment being compared to a population in another, the difference is the environment. a car population of one make being compared with a car population of a different make, the thing being compared is the manufacturing and design.

At this point I don’t know how to be anymore clear, and I’m done trying. If you still don’t understand, that’s on you.
