    Several are mentioned in the article, eg: While meat was definitely a caloric bonanza for early humans, recent primate studies offer evidence that sugary fruits continued to be a critical “brain food.” A 2017 paper looked at 140 primate species and compared their brain sizes with their diets. “What [that study] showed very clearly was that the fruit-eaters, the frugivores, had 25 percent bigger brains, on average, than the folivores, the leaf-eaters,” Brand-Miller says. The fruit-eaters also had bigger brains than the omnivores, which ate meat. which is one thread of the argument laid out in: A central role for dietary sugars in human evolution - https://www.science.org/doi/10.1126/science.aed8437 https://www.science.org/doi/10.1126/science.aed8437 the paper centrally discussed.

      Funny how science deniers will downvote anything that doesn’t fit their world view
