Actually the slide presentation is all science.
I’ll hop in on your post to make an additional footnote
As a tangential trip, the story is strong on Melungeon connection. My area is experiencing a strong interest in the Melungeon culture. Suppressed for perhaps two hundred years, people are keen to study and understand their heritage.
It started when an academic, Brent Kennedy, became ill and was hospitalized at Emory in Atlanta. There was a diagnostician who correctly diagnosed him with a disease genetically related to obscure Mediterranean cultures. That was news to him. He was raised in Southwest Virginia. Thus began his quest and the annual meetings in Kingsport of hundreds of folks who come to learn about their Melungeon heritage.
Melungeons were called racial tripartiates with one of the groups being Cherokee.
There is much more here than is revealed by a casual glance.
East Tennessee was the capitol of Cherokee land and the remote hollows and ridges were home to most of the Melungeons.
By the way, in the book by the French colonist Laudinarre in 1562, his troops visited East Tennessee on a trade mission from far away Ft Caroline at what is now Mayport, Jacksonville Beach Florida.
Hmmmmmmmmmmmmm
