None of them, individually, resolves all questions.
Together, they are building a picture that is more complex than the simple Clovis First model and more complex than any single coastal-migration model.
Arlington Springs, without ancient DNA, cannot contribute to the genetic picture.
It contributes instead to the geographical and chronological picture: coastal California, terminal Pleistocene, island context requiring maritime capability.
The bones locate a person, not a genome, but location is sometimes the most important information.
