Well if you want to not sound like a knownothing - when you speak of gravity in physics you wont be saying that unless something is “important” it has no “gravity” - similarly when speaking of evolution in a biological context - it doesn't just mean change - it has a specific meaning - that of change in the DNA of a population.

So while you might say that Asians moving to America and raising their children on a Western diet is an “evolution” (change) in how tall Asian Americans are - it would be absolutely incorrect to say that this was a result of biological evolution (change in the DNA of a population).

Wrong. “Gravity” used that way is just fine. It is an expansion of the word by analogy and comparison. Your restrictive use of the common word “evolution” is an attempt to claim exclusive use of it for a particular subset of meanings, an attempt to jargonize a common word. If you want the word to be allowed only a particular portion of its former meaning then you must add qualifiers. Evolution, without qualifiers, is any gradual change or series of changes that leads from one state or situation to another.
