Did humans begin snacking to sharpen their teeth?We often claim that humans are a disastrous pest that was awarded to Earth. But in reality, we just act like any other dominant creature would do. Cats, wild ones, often maraud their ecosystems as they are on the absolute top. But we think animals don't have a habit of snacking because snacks are a uniquely human idea.
Animals surely do hunt for sport but they lack the ability to snack. But there is a thing animals, especially mammals do a lot. Animals bite stuff so they can sharpen their teeth. Since herbivores browse most of the times and grass is enough to polish their teeth, we are excluding them out. Omnivore and carnivore animals are often seen teething things. So is the human habit of snacking on small nuggets of food, a variation of teeth sharpening? Human babies do teething on their toys and people as their teeth develop. Maybe this habit of sharpening our teeth let us snack. Maybe that's in our genetic software. What do you all think?
