Researchers Claim Sasquatch Drove Human Self-Domestication

# Did Sasquatch Hunt Our Ancestors? Creek Devil Dives Into a Wild Theory About Human Evolution Creek Devil, hosted by longtime field researcher and two-time witness William Jevnik, dropped a fascinating campfire discussion that connects some pretty mind-bending dots between human evolution, domestication syndrome, and the possibility that Sasquatch once preyed on our ancestors. If you've ever wondered why humans seem to have "softened up" over the millennia, this theory might just flip your understanding of history upside down. The conversation kicks off with Jevnik reading about **domestication syndrome**, a real scientific concept describing the permanent changes that happen to species when they're domesticated. We're talking smaller brains, reduced tooth size, changes in cranial structure, less aggression, and even cuter, more juvenile facial features. Sound familiar? Because researchers have proposed that humans show many of these same traits compared to our ancestors from 20,000 to 50,000 years ago. Then things get really interesting. Jevnik brings up Danny Vendettini's book *Them and Us*, which proposes that around 40,000 years ago, Homo sapiens nearly went extinct. The culprit, according to Vendettini, wasn't Neanderthals, but rather another hominid species that was actively hunting us. The trauma of that near-extinction event supposedly triggered a kind of self-domestication in humans. We became more cooperative, more social, and less aggressive as a survival mechanism. And if we eventually wiped out whatever was hunting us, there would be no record of them existing. The species would simply be forgotten. One of the panelists makes a compelling point about Neanderthals. Since modern humans carry Neanderthal DNA, there clearly wasn't enough animosity to prevent interbreeding. So if something was hunting both groups, it makes sense that the more cooperative species (us) would survive while the less cooperative ones (Neanderthals) might not. The theory even suggests that Sasquatch could be the very creature that drove this entire transformation, and that our ancestors' "forgetting" of them is exactly why mainstream science dismisses the idea today. The discussion also touches on bonobos versus chimpanzees. Bonobos are genetically close to chimps but far less aggressive, have smaller craniums, and don't engage in lethal group conflict. They're essentially the self-domesticated cousins of chimpanzees, and they show many of the same traits listed in domestication syndrome. If bonobos can do it, why not humans? It's a thought-provoking watch that blends real science with Sasquatch lore in a way that actually makes you pause and consider the possibilities. Jevnik and his guests don't claim to have all the answers, but they raise questions that mainstream researchers tend to avoid entirely. Definitely worth checking out the full conversation over on the Creek Devil channel.
