The Windover burials in Florida were "proven" to have "European" ancestry by DNA. Is this still believed to be true?

In a documentary I've seen about the Windover burials, a DNA scientist

Scientists report findings in scientific journals, not on Youtube or cable television.

Stuff attributed to "a DNA scientist" on basic cable is . . . nothing.

"Resembled European DNA" means nothing. There's a long history of spurious findings that "someone thought" remains "looked like" Vikings, Chinese, whatever. Rather random forensic reconstruction of Kennewick Man lead to an assertion that he "looked European".

When real "DNA scientists" recovered his DNA and sequenced it, they reported it in Nature, not on basic cable-- and it most closely resembles the Native Americans who live nearby today.

The ancestry and affiliations of Kennewick Man

unfortunately, I keep coming across white supremacists who try and use that story to undermine Native American sovereignty.

You assume that racists might change their mind if you point out that they're wrong about stuff. Give it up. They don't care. They didn't come by their views through scientific inquiry, nor will it cause them to abandon them.
