Okay, no doubt by now some of you have heard all about the news that some “scientist” claims to have sequenced the DNA of Bigfoot, concluding that Bigfoot is at least partially human. Specifically, according to the following LiveScience.com article by my skeptical colleague Benjamin Radford…
Genetic testing confirms the legendary Bigfoot is a human relative that arose some 15,000 years ago — at least according to a press release issued by a company called DNA Diagnostics detailing supposed work by a Texas veterinarian.
The release and alleged study by Melba S. Ketchum also suggests such cryptids had sex with modern human females that resulted in hairy hominin hybrids, but the scientific community is dubious about her claim.
“A team of scientists can verify that their five-year long DNA study, currently under peer-review, confirms the existence of a novel hominin hybrid species, commonly called ‘Bigfoot’ or ‘Sasquatch,’ living in North America,” the release reads. “Researchers’ extensive DNA sequencing suggests that the legendary Sasquatch is a human relative that arose approximately 15,000 years ago.”…
Ooh! Bigfoot-human hybrid freaky furry sex! Are you interested yet? ;)
Seriously, this is just beyond stupid, folks. And a little deeper look at the article points out exactly why this whole thing is, at best, viewed with a decidely skeptical eye and, at worst, deserves to be roundly derided in every corner of the Internet for the cryptozoological flummery it most likely is:
… So where’s the evidence? Well, there is none. Not yet, anyway: Ketchum’s research has not appeared in any peer-reviewed scientific journal, and there’s no indication when that might happen. 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. Until then, Ketchum has refused to let anyone else see her evidence. … [emphasis added]
So let me get this straight: she puts together a press-release claiming that she’s made this amazing discovery that could very well change most everything we know about human/hominid anthropology and evolution, yet she is unwilling to allow her scientific peers to see the evidence and examine it for themselves?
That’s kind of the opposite of the way science is supposed to work, Dr. Ketchum. You would think that a supposedly serious researcher would know that – that is, assuming that she’s a serious scientific researcher and not just some kind of glory-seeking pseudoscientific crypto-hack. When making such an extraordinary claim, not allowing your scientific peers to examine your evidence is tantamount to saying “I’m right because *poof* magic!” In other words, it is not convincing at all, and it speaks to your credibility being somewhat minimal.
Last, but certainly not least, there is a very well-worded criticism by Ben Radford about how one is, exactly, to know that the DNA sequenced is actually that of a previously uncataloged Bigfoot-ish creature (a question which I had in mind when first hearing the claim):
… How did the team definitively determine that the samples were from a Bigfoot? Did they take a blood or saliva sample from a living Bigfoot? If so, how did they get that close, and why didn’t they simply capture it or photograph it? If the samples were found in the wild, how do they know it wasn’t left by another animal — or possibly even a hunter, hiker or camper who left human genetic material?
Previous alleged Bigfoot samples subjected to DNA analysis have been deemed “unknown” or “unidentified.” However, “unknown” or “unidentified” results do not mean “Bigfoot.” There are many reasons why a DNA sample might come back unknown, including that it was contaminated or too degraded by environmental conditions. Or it could simply mean that the animal it came from was not among the reference samples that the laboratory used for comparison. There is no reference sample of Bigfoot DNA to compare it with, so by definition, there cannot be a conclusive match. …
Of course, I suppose the answers to these and similar questions will have to go unanswered because we expect Dr. Ketchum to act like a real scientist and share her samples, data, research, and methodology for actual peer review and analysis. Hah – silly us! :)

It was with much interest that I read the following NPR story on the question of Christian evangelicals acceptance (or not) of evolutionary science. I wanted to just highlight a few key parts of the story and give my thoughts on this interesting development…
Let’s go back to the beginning — all the way to Adam and Eve, and to the question: Did they exist, and did all of humanity descend from that single pair?
According to the Bible (Genesis 2:7), this is how humanity began: “The Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.” God then called the man Adam, and later created Eve from Adam’s rib.
Polls by Gallup and the Pew Research Center find that four out of 10 Americans believe this account. It’s a central tenet for much of conservative Christianity, from evangelicals to confessional churches such as the Christian Reformed Church.
But now some conservative scholars are saying publicly that they can no longer believe the Genesis account. Asked how likely it is that we all descended from Adam and Eve, Dennis Venema, a biologist at Trinity Western University, replies: “That would be against all the genomic evidence that we’ve assembled over the last 20 years, so not likely at all.” …
What I find so interesting about this situation is that these evangelical scholars are going against the grain of the traditional belief in a literal Adam and Eve. One has to wonder how the broader evangelical community will react: will they seriously reconsider these traditional beliefs, will they dismiss the scholars because their creationist interpretation of Genesis trumps all, or will they seek to label these scholars as “heretical” and seek to purge them? I think the likely scenario is a combination of all three, but it seems that some prominent Christian evangelical institutions are seeking the second and third possibilities. On the one hand, some institutions are choosing to ignore scientific reality:
“From my viewpoint, a historical Adam and Eve is absolutely central to the truth claims of the Christian faith,” says Fazale Rana, vice president of Reasons To Believe, an evangelical think tank that questions evolution. Rana, who has a Ph.D. in biochemistry from Ohio University, readily admits that small details of Scripture could be wrong.
“But if the parts of Scripture that you are claiming to be false, in effect, are responsible for creating the fundamental doctrines of the Christian faith, then you’ve got a problem,” Rana says.
Soooo, when hard scientific evidence from nature contradicts you interpretation of Genesis, you ignore what nature says? Yeah, that’s dumb. No wonder people who don’t already buy into this particular theology tend to think it’s downright silly.
What’s worse, other Christian evangelical institutions are going even further and actively working to “expel” scholars who don’t toe the literal line on Genesis:
Several other well known theologians at Christian universities have been forced out; some see a parallel to a previous time when science conflicted with religious doctrine.
“The evolution controversy today is, I think, a Galileo moment,” says Karl Giberson, who authored several books trying to reconcile Christianity and evolution, including The Language of Science and Faith, with Francis Collins.
Giberson — who taught physics at Eastern Nazarene College until his views became too uncomfortable in Christian academia — says Protestants who question Adam and Eve are akin to Galileo in the 1600s, who defied Catholic Church doctrine by stating that the earth revolved around the sun and not vice versa. Galileo was condemned by the church, and it took more than three centuries for the Vatican to express regret at its error.
The great irony here is that so many of these same Christian evangelical organizations made such a big deal a few years back when the failed film “Expelled: No Intelligence Allowed” came out. “Expelled” argued that secular academia was forcing out scholars who dared to question evolutionary science; now, in fact, we see the hypocrisy behind these arguments. For years, we’ve heard these folks bitch and moan at length about some supposed conspiracy to discriminate against them, yet they are the ones purging “heretics” from their ranks because these scholars follow science as opposed to a blind allegiance to certain theological interpretations of the Bible.
Last, but not least, is a word of warning from the article. Christians, take note:
“When you ignore science, you end up with egg on your face,” Giberson says. “The Catholic Church has had an awful lot of egg on its face for centuries because of Galileo. And Protestants would do very well to look at that and to learn from it.”

In a recent TED Talk Michael Specter, a science & technology journalist and author of “Denialism: How Irrational Thinking Hinders Scientific Progress, Harms the Planet, and Threatens Our Lives”, expresses quite eloquently the dangers of buying into various forms of nonsense such as anti-vaccination, opposition to genetically-modified foods while embracing “organic food”, and alt-med herbal woo…
