Hate to say I told you so but ...
The Starchild Skull was confirmed to be 100% human.
thefieldreportscom.wordpress.com...
According to the report:
" However, no modern comparison samples were submitted with this batch from the archaeologists or any other individual who may have handled the sample and potentially contaminated it. Therefore, we cannot guarantee that these profiles are authentic and not a previous handler."
In other words, the lab could not rule out the possibility of prior contamination of the samples tested by human handling. Given the provenance of the skull and the amount of handling it has received, this weakness totally invalidates the conclusions of the lab that the skull is that of a male human. A proper scientific response - as opposed to a knee-jerk reaction - must be that no scientific conclusion can be drawn from the tests because they could not rule out the possibility of contamination.
Hate to say it, but you are all jumping to conclusions over a report that appears to confirm your long-held suspicions about the Pye skull being human but which does not if you stick to scientific logic and stop ignoring the possibility of prior contamination.

I'd point out to you that it was Pye himself that started this starchild dna analysis shtick in the first place and he couldn't rule out contamination either.
You can thank Pye for any contamination if it exists by the way. He didn't know how to handle such a relic but that didn't keep him from getting his hands all over it.

I keep asking the poster he won't show me where he finds that in my source. I can't find it.

You can find the qualification on page 6 of the report here. I quote:
"The combination of replication, fragment sizes obtained, procedures in place for laboratory sterilization and elimination of Paleo-DNA Laboratory DNA profiles suggest the results are authentic and not contamination. However, no modern comparison samples were submitted with this batch from the archaeologists or any other individual who may have handled the sample and potentially
contaminated it. Therefore, we cannot guarantee that these profiles are authentic and not a previous handler."
The last sentence TOTALLY renders inconclusive the lab's findings.
The combination of replication, fragment sizes obtained, procedures in place for laboratory sterilization and elimination of Paleo-DNA Laboratory DNA profiles suggest the results are authentic and not contamination.
Controls were run at every step of the analysis and gave expected results. The above profiles do not match any staff member or laboratory user at the PaleoDNA Laboratory, past or present.
