Dr. Melba Kecthum is excited about new DNA extraction techniques |
"One is from Dave Paulides since he has put that out publicly and another from Mike Rugg since he has also openly discussed it." --Dr. Melba Kectchum Responding to where did the bone samples come from.
Dr. Melba Ketchum announced she will be working on teeth and bone samples in pursuit of Bigfoot DNA. The technique she will be using is a technique taught to her from a Dr. Pat. According to
Dr. Ketchum, Dr. Pat has never failed at getting DNA from bone and has developed the extraction techniques that have identified people for the military, including the soldiers buried in the Tomb of the Unknown.
As a side note, anonymity of the entombed soldier is key to the symbolism of the monument: since the identity is unknown, it could theoretically be the tomb of anyone who fell in service of the nation in question, and therefore serves as a monument to all of their sacrifices. Symbolism is great, but families their fallen identified and post-Vietnam soldiers may never be unknown again. You can read about the last identified soldier in this
Washington Post article.
Getting back to
Dr. Ketchum, she seems very excited about the techniques and makes a distinction between forensic scientist and academic scientist. Read an excerpt from her announcement on facebook below.
[Dr. Pat] taught me the technique, but he has the wonderful robots that make extractions more perfect than I could ever do manually. He has never failed to get DNA from bone. Even manually his techniques are SO fantastic that I was able to get usable DNA from cremated remains in two separate cases (one cat and one human) and I never thought we could do that, especially without robots. We recently extracted DNA from some 2000 year old tissue and hair and got good results (DNA profiles) using these extraction methods without having to amplify the DNA (WGA) or make a "library" like they did for the Neandertal and Denisovan hominins prior to sequencing. We have one sample that is highly degraded bone and it will be interesting if this will be the first time this extraction technique fails. I am betting on getting DNA though. The academics could sure learn a few things from forensic scientists about extracting good DNA from minimal samples and also how to determine if there is really contamination other than just assuming that there is... It is so awesome! I gotta love science!!!!
We actually know quite a bit about the tooth from
Mike Rugg. It is a fairly large molar, decidedly primate according to Mike and was found in 2002 during a shark tooth dig in Scotts Valley, California. You can watch
Mike Rugg talk about the toothe in the video below.
CORRECTION: The initial version of this post claimed Dr. Pat has been responsible for identifying people for the military, more accurately Dr. Pat has been responsible for developing the extraction techniques that have identified people for the military. The post has been changed to reflect the correction.
