New Gene Discovery May Explain Rapid Human Brain Evolution

New Gene Discovery May Explain Rapid Human Brain Evolution

A revealing new study on human evolution and brain development has just been published. Could this lend credence to the stoned ape theory of brain evolution?

About 300,000-800,000 years ago the human brain experienced a massive and accelerated growth spurt. Scientists have offered many explanations for how and why this may have occurred, but a new study out of Boston Children’s Hospital focused on a fast-evolving set of the human genome called human accelerated regions (HARS). Previous studies have found about 3,100 HARS during brain development, but the team at Children’s Hospital determined one HAR gene PPP1R17 could be responsible for or play a significant role in, rapid brain development. Further, they discovered this works differently in humans than in other animals.

Ben Stewart, the host of Gaia’s Limitless series, said,”[T]hese regions of the human DNA may hold some kind of an answer at the rapid explosion of human neo-cortex because if you think of it evolutionarily, there’s not been one creature, at least on planet Earth, that has been studied that had any organ increase in size as large and as rapidly as the human brain did, so there’s definitely some unanswered questions there.”

“I’m pretty sure that these HARS regions are being looked at for something very unique in the evolution of the brain, and my own personal twist on it is this also might be important when we start looking at brian-machine interfaces and how the brain can potentially cause mutations to adapt to some kind of technology in the brain to enhance or evolve the human brain,” Stewart said.

How could this new discovery be related to the Stoned Ape theory?

“There’s a possibility that the Stoned Ape theory could lead into this. Now, the Stoned Ape theory was really popularized by Terence McKenna,” Stewart said. “Over time, you would have some of our ancient ancestors, hominids, that would be following behind bovine creatures, cows, and in the cow patties in the fields that would naturally, having followed these creatures around for hundreds of thousands of years or whatever it might have been, that they would have started eating the mushrooms, the psilocybin mushrooms that grow naturally in cow patties. These experiences tickling the language centers and other parts of the brain, bringing down the rigidity of the default mode network, and activating other communication hubs within the brain, that could actually explain the rapid explosion of the human neocortex.”

“In this article, they’re saying that these human accelerated regions act differently in humans than they do in primates or creatures like mice and ferrets that they’ve looked into now. So, potentially if there is some connection with the Stoned Ape theory, that psychedelics or psychotropics helped in the expansion of the human neocortex, and made us as, at least psychologically, so much different than the rest of the creatures on Earth, then there may be something to look at here.”



Ayahuasca Study Shows Breakthrough in Resolving Intercultural Conflict

Ayahuasca Study Shows Breakthrough in Resolving Intercultural Conflict

Can plant medicines heal long-standing, sociopolitical conflicts? A new study brought together groups with deep-rooted enmity for each other in an ayahuasca ceremony—could this be the solution for a more peaceful world?

Plant medicines, including ayahuasca and psilocybin from “magic mushrooms” have become breakthrough therapeutic modalities for treating depression, anxiety, and addiction, as taboos around psychedelics fade and scientists study their effects in sanctioned clinical settings. And now a group of scientists from the US, UK, and Israel has begun to look at ayahuasca as a tool for resolving intercultural conflict. By bringing together Israelis and Palestinians for a group ceremony, the researchers looked for signs of reconciliation and intergroup contact between the subjects.

Dr. Maya Shetreat MD, is a neurologist and herbalist specializing in plant medicine and psychedelic-assisted therapy. She had this to say about the recent study…

“We should definitely be able to experience significant shifts in identity politics because we know that psychedelic medicines like ayahuasca or psilocybin have these ego-dissolving properties that change the way our brains see us, see our identity, and perceive us as being separate from one another,” Dr. Shetreat said. “So, theoretically it’s possible that any kind of identity issues, whether it be political or otherwise, could be more in a place of resolution because people can see past differences.”

Results of this recent study proved to be profound, with several participants reporting visions in which they re-lived trauma from the perspective of those from the opposite culture. And in one instance, a participant was able to embody a single experience from both perspectives. 

But while these results held significant weight for those involved, how does this translate at a larger scale? 

“You know we have to ask the question, is it really necessary for everyone to be in ceremony and go through a psychedelic experience in order to create change? And actually, I think there’s an argument that it doesn’t take that many people, not everybody has to be in that role and enter that liminal space. The people who are called and the people who are motivated to engage with the medicine have those revelations, integrate, take action, and actually lead other people to see those connections that other people might not be able to see,” Dr. Shetreat said.
