The debate is over! Humans are anatomically and physiologically designed to eat only plant food. Homo sapiens (humans) are classified broadly as land mammals and more specifically as tailless primates. Our closest cousins, gorillas, bononobos and chimps eat predominantly plant material with a few insects here and there. Chimps will, on occasion eat flesh foods but is it more “ceremonial” to demonstrate territorial claims and celebrate won skirmishes with other tribes, but this is rare.
