The recent discoveries of 9000-12000 year old skeletal remains in the Americas have begun to change our understanding of who originally entered the Americas at the end of the last Ice Age. Discoveries such as Washington state's 'Kennewick Man', Brazil's 'Luzia', and Alaska's 'Prince of Wales Island Man' have challenged the archaeological and geological status quo. The First Americans explores these new discoveries by using racial classifications and micro-evolutionary techniques to better understand the complex relationships between the first Americans and living Native Indian groups.
