That the founding population of the Americas included at least two distinct branches — the Ancient Beringian lineage and the ancestors of other sampled Native Americans — before the main southward expansion began.
That the Ancient Beringian lineage was genetically part of the Native American founding stock, not a separate non-Native population.

Whether there were one or multiple distinct founding migrations from different Asian source populations.
The cultural practices, language, social organization, or beliefs of the people USR1 belonged to.
