Thanks, I've seen this before. Negroids also turn up everywhere. I will caution you to take articles by Clyde Winters with a grain of salt though.
I kinda figured a grain of salt was in order there :) That's one reason in my excerpt I included the Chang source he cites--I want to see if I can get ahold of that and see where he's getting that from. It does get me wondering about the Negroid features found in places like Melanesia, though.
