“Perhaps ‘evolved’ was misused here.”
Obviously, they didn’t mean genetic evolution. Though there are certainly some genetic differences. It’s more like how rock ‘n’ roll “evolved” from the blues. Except, as stated, genetics has a tiny little bit to do with it.

OK. So I evolved from my English paternal grandmother and my Scottish paternal grandfather, and of course my Irish/Dutch maternal grandmother and my Irish/German maternal grandfather into an American. Got it. That does, at least, explain why I’m a pastie white boy. ;^)
