Screening the hair Before the hair was considered for testing it was first screened to ensure it was not human or any other known animal. The following is the documentation from the DNA Study of how the hair was screened. Hair Analysis: From the DNA Study: Hair samples were sent to the Southwestern Institute of Forensic Sciences (Dallas, TX) for analysis. (Mr. David Spence) The samples were evaluated visually, stereoscopically, and by light microscopy to determine human or animal origin. Hairs that were classified as potential novel hominid were also evaluated for DNA typing potential by examining for root material. Only hairs that were not human in appearance and could not be identified as any other species were utilized in this study.
