the European faces question is an interesting one. National Geographic has a website that shows the migration of human beings from Africa into Europe and towards Asia. This leaves you with a strong sense that the migration followed the grasslands that came out of the receding ice. As the ice move north the grass did to and with that came grazing animals and people. I couldn't help but notice that something in what you said reminded me of the similarities of people over time.

If you read first-person histories, where a person put down in writing what was going on around them, what they were thinking, and how people interacted with each other, his show something interesting. The ancient mind and the modern mind think remarkably alike, given a similar situation. This is off track a bit but nonetheless I couldn't help but think of it. Good luck and I'll be following you
