Dr. Melba Ketchum Q&A: Sasquatch Origin, Neanderthal DNA
Dr. Melba Ketchum has a paper currently in peer-review that will help prove the existence of Bigfoot. She has a public Facebook page where she takes time from her busy schedule to answer some questions unrelated to the paper.
Here's the latest Q&A:
Question: I did not know that was where the name Sasquatch originated.
Answer: It is derived from a the Salish language called Sésquac or Saskehavas. Though all of the different Native American Tribes have their own names for Sasquatch, in the 1920s, J.W. Burns, a journalist, started to take the stories from the Native American culture. In the resulting series of Canadian newspaper articles, Burns coined the name "Sasquatch" from the word "Sésquac", meaning "wild man".
Question: How do you get Neanderthal DNA? bone marrow? hair. perhaps?
Answer: Usually bones or teeth are used. The hair is usually not available and is already gone. The bones/teeth are cleaned, ground up and then digested leaving the exposed DNA available. Bones carry DNA and it is somewhat protected due to the layers of minerals making up the bone's matrix that protect the bone cells. When something dies, the bone's matrix makes it more difficult for decomposition to occur, keeping bacteria out to a degree. The cells sometimes dry out before bacteria destroys the DNA in the bone cells. When this is the case, you can retrieve DNA from bones if enough of the cells were protected from bacterial degradation. Teeth are actually a better source of DNA than bone in many cases because the outside of the tooth protects the interior.
Question: I thought I heard somewhere awhile ago that all modern humans outside of parts of Africa have Neanderthal DNA in some small degree - 1 to 5% or so. Is this so?
Answer: Yes, non-Africans have been proven to carry a small percentage of Neanderthal DNA. There are also other peoples that show remnants of a Denisovan cross also.
