BBC News - Americas 'settled in three waves'

The biggest survey of Native American DNA has concluded that the New World was settled in three major waves.
But the majority of today's indigenous Americans descend from a single group of migrants that crossed from Asia to Alaska 15,000 years ago or more.
Previous genetic data have lent support to the idea that America was colonised by a single migrant wave.
An international team of researchers have published their findings in the journal Nature.
