The skulls of the first Americans were thick and rugged, with heavy brows and protruding faces as opposed to the lighter brows, set back faces and thinner features of more modern Americans. What explains this?

• Modern Native Americans came from Europe instead of Asia

• The first Americans came from India across Antarctica, while the Native Americans came from Australia on a boat.

• There is no explanation

• The first migrants were composed of different phenotypes, but over time, with interbreeding and isolated evolution, their appearance changed.
