A team of eleven scientists with expertise in genetics, forensics, pathology, biochemistry, and biophysics has sequenced three whole nuclear genomes from a novel, contemporary species of hominin in North America. The study, Novel North American Hominins, Next Generation Sequencing of Three Whole Genomes and Associated Studies, which analyzed DNA from a total of 111 high-quality samples submitted from across the continent, appears in the inaugural issue of Denovo: Journal of Science (http://www.denovojournal.com) on February 13.
The team, led by Dr. Melba S. Ketchum, DVM, of DNA Diagnostics in Nacogdoches, TX, sequenced the three whole nuclear genomes using the next-generation Illumina HiSeq 2000 platform at University of Texas, Southwestern from a tissue sample, a saliva sample, and a blood sample. The three genomes all attained Q30 quality scores above 88 on the Illumina platform, significantly higher than the platform average of 85, indicating highly-purified, single-source DNA with no contamination for each sample. The three Sasquatch genomes align well with one-another and show substantial homology to primate sequences.
In addition to the three nuclear genomes, Ketchums team also sequenced 20 whole and 10 partial mitochondrial genomes from the Sasquatch samples. In contrast to the nuDNA results, the Sasquatch mtDNA was fully modern Homo sapiens, indicating that the species is a hybrid cross between modern Homo sapiens in the maternal lineage and an unknown hominin male progenitor.

DeNovo. 13 February 2013.
Specimens yielding DNA were obtained, purportedly from elusive hominins in North America called Sasquatch. Sequencing and genotyping were performed in addition to histopathologic and electron microscopic examination of a large tissue sample.
Mitochondrial whole genomes were consistent with modern humans. In contrast, novel data were obtained when nuclear DNA was sequenced. Next generation whole genome sequencing was performed on three samples. Phylogeny trees generated showed homology to human chromosome 11 and to primate sequences. The data indicates that the Sasquatch has human mitochondrial DNA but possesses nuclear DNA that is a structural mosaic consisting of human and novel non-human DNA.
