Ron Put Posted August 5, 2021 Report Share Posted August 5, 2021 So much for the "paleo diet" :)Findings on Neanderthal oral microbiomes offer new clues on evolution, health A new study looking at the evolutionary history of the human oral microbiome shows that Neanderthals and ancient humans adapted to eating starch-rich foods as far back as 100,000 years ago, which is much earlier than previously thought. The findings suggest such foods became important in the human diet well before the introduction of farming and even before the evolution of modern humans. And while these early humans probably didn’t realize it, the benefits of bringing the foods into their diet likely helped pave the way for the expansion of the human brain because of the glucose in starch, which is the brain’s main fuel source. “We think we’re seeing evidence of a really ancient behavior that might have been part of encephalization — or the growth of the human brain,” said Harvard Professor Christina Warinner, Ph.D. ’10. “It’s evidence of a new food source that early humans were able to tap into in the form of roots, starchy vegetables, and seeds.” Quote Link to comment Share on other sites More sharing options...
