In the video the guy claims they werent able to conclude the origins of the DNA in the skull, according to wiki that isnt true.

http://en.wikipedia.org/wiki/Starchild_skull

DNA testing in 1999 at BOLD, a forensic DNA lab in Vancouver, British Columbia found standard X and Y chromosomes in two samples taken from the skull, "conclusive evidence that the child was not only human (and male), but both of his parents must have been human as well, for each must have contributed one of the human sex chromosomes".[7] Further DNA testing at Trace Genetics, which specializes in extracting DNA from ancient samples, in 2003 recovered mitochondrial DNA from both skulls. The child belongs to haplogroup C. Since mitochondrial DNA is inherited exclusively from the mother, it makes it possible to trace the offspring's maternal lineage. The DNA test therefore confirmed that the child's mother was a Haplogroup C human female. The adult female belongs to haplogroup A. Both haplotypes are characteristic Native American haplogroups, but the different haplogroup for each skull indicates that the adult female was not the child's mother. Trace Genetics obtained nuclear DNA, which contains chromosomes from both the father and the mother, from the adult female, but was not able to recover useful lengths of nuclear DNA or Y-chromosomal DNA of the father from the Starchild skull, despite conducting six consecutive tests. The founders of Trace Genetics stated that "[t]he inability to analyze nuclear DNA indicates that such DNA is either not present or present in sufficiently low copy number to prevent PCR analysis using methods available at the present time."
