While I think your point rings true, trying to use your historical examples to point it out dismisses human migration among other factors that may have contributed. For instance, there is a good chance that most "Spartans" have died off as a people, since their population problems are well documented. and both the army of Alexander the Great, and the Roman Empire are armies of much larger territory then current Italy/Greece in their peak. And much of Macedonia of Alexander's early reign isn't part of what's typical Greece today. That's just nit-picking about the complexities of history, but I do agree that the point that people and cultures can change is very true!
