Our early ancestors in Africa were arboreal troop-monkeys, living on a diet of fruit (to quote Yogi Bear, 'Nuts and berries! Nuts and berries! Yech!') and insects. When you wander around the house, not particularly hungry, but looking for something to munch on idly, what you are most likely seeking unconsciously are bugs. Most of our most popular snack foods (Fiddle-Faddle comes to mind, and small pretzels) resemble and have the same 'mouth feel' as bugs. You can take the monkey out of the trees, but you can't take the tree monkey out of humanity.
