The various tribes have many different facial features that indicate the effect of many different waves of migration.

I'm very curious if DNA analysis can determine if "European" DNA is the predecessor to some "American" DNA or if they both have a common root from a third source.

IMO mankind has been criss-crossing the Americas for 10s of thousands of years.

James Chatters (Kennewick Man Archaeologist) in his book Ancient Encounters speculates that Kennewick Man was from a stock of humans that became Asian and migrated back and became the Europeans too. He thinks it was the Kennewick Man type that migrated all along the coast of North and South America, crossed across Panama and migrated up the East Coast Of The US. The Windover folks may be related to Kennewick Man (and others) that don't quite fit the 'land bridge' model. He thinks the 'land bridge' Asians came later. American Indian (as we know them today) skeletons older than 6,000 years have ever been found anywhere in the Americas.

Caucasion tribes could have crossed into the Americas from the ice bridge as well as Mongoloid tribes. No need to invent voyages from Europe to get them to the Americas. Though I am sure rare voyages did take place but not enough to change the genetic character of the native peoples.
