Nature has distinction. All its creations have distinctions too. Their nature, habits, character and mannerism are distinct. Consumption of liquids is a clear example. All herbivores gulp and swallow water, including human beings. Carnivorous animals use their tongue and lick liquids. There is this obvious distinction between Carnivores and Herbivores beings of nature. Look into nature. Spend some time with her alone. It is a great teacher.
