While trying to find out more about this skull, I came across dozens of articles, but nothing from mainstream science sources or universities. The Wikipedia article says the mothers dna is accounted for as native american human, but can't get a good enough sample for the father... also the Wikipedia article sources the last dna test as of 2003. The article also suggests:
"Potential explanations for the skull's unusual features, apart from the alien-hybrid hypothesis, include the use of cradle boarding on a hydrocephalic child, brachycephaly and Crouzon syndrome."
Loyd Pye says the most recent 2010 dna test is showing evidence of alien dna via in-vitro feritlization techniques between aliens and a human mother.
Keeping an open mind does not require me to believe Pye, he's the one making the claim that would change a lot of our current beliefs about the world and the universe beyond. I'm going to need a hell of a lot more proof that this is a human-alien hybrid from 900 years ago in Texas.
I'm a lot more excited about this meteorite than about this skull.
