The first Indian "tribe" wasn't actually Indian, according to British researchers who studied the skulls of a tribe based in Mexico.

Researchers from Liverpool John Moores University say the skulls of the Pericues Tribe aren't similar to those of current-day tribes. They say they are more similar to people southern Asia, Australia, and the South Pacific Rim.

That has archaeologist Silvia Gonzalez thinking the first Americans came by boat. She says they took an "island hopping" route to what is now the Pacific Coast.
