"If the data are good and the science is sound, any reputable science journal would jump at the chance to be the first to publish this groundbreaking information," Radford, the deputy editor of Skeptical Inquirer magazine, wrote in LiveScience.com.
Radford suggests that if the mitochondrial DNA is identical to Homo sapiens (modern humans), it could mean one of two things.
"The first, endorsed by Ketchum, is that Bigfoot ancestors had sex with women about 15,000 years ago and created a half-human hybrid species currently hiding across North America.
"There is, however, another, simpler interpretation of such results: The samples were contaminated. Whatever the sample originally was -- Bigfoot, bear, human or something else -- it's possible that the people who collected and handled the specimens accidentally introduced their DNA into the sample, which can easily occur with something as innocent as a spit, sneeze or cough," Radford wrote.
In LiveScience.com, Radford pointed out that since "There is no reference sample of Bigfoot DNA to compare it with, by definition, there cannot be a conclusive match."
