[The way the conclusions of this study were announced is a little misleading. This study has not disproven the Solutrean Hypothesis and it has not actually proven all Native Americans came from Asia by way of the Bering Strait. In fact there is no way you could say that the study DOES prove that: What it DOES say and say very clearly is that all the Native Americans were related to each other and come from common ancestors. This is saying that all people with the Q group Y DNA are related, the study is talking about the Q group.
