Claim (sort of) that carb-heavy diet fueled Neanderthal brain growth

Joining the queue of theories about how the human brain (the most significant force in the natural universe) came to exist:

New research examining bacteria collected from Neanderthal teeth suggests that our hominid cousins’ diets were heavy on roots, nuts and other starchy, carbohydrate-rich foods at least 100,000 years ago, reports Ann Gibbons for Science. Shifting to eating high-calorie starches as a dietary staple may have been essential for fueling the evolution of our large human brains, and this study pushes back the earliest evidence of that shift.

“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,” says Christina Warinner, an anthropologist at Harvard University and co-author of the research, in a statement. “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.”

Okay, so nuts did it. The thing is, fat, meat, and starch have all been blamed for the big human brain. When do we get round to spices and salt? They’ve been unjustly neglected.

    I halfway recalled something about spices and brain size. Googled, and sure enough, it’s there!

    I’d better get started on salt, then. Probably something to do with the aquatic ape.
