Human beings are omnivores.
- The term "omnivores" refers to generalized feeding i.e., they can consume both plants and meat.
- They have specialized adaptations for gathering, eating, and processing food that contains both plant protein and animal protein. McArdle goes on to say that omnivores are primarily "opportunistic" feeders that take advantage of food opportunities in order to survive.
- They exhibit more universal physiological and anatomical characteristics. One such feature is the human dentition (set of teeth). It proves that the human diet is by nature omnivorous and not herbivorous given the presence of canine teeth for tearing flesh and molars for grinding and chewing.
- Our digestive system is shorter than that of a herbivore and longer than that of a carnivorous animal. A characteristic of omnivores is this.
- Vegetation requires a longer digestive system as that of herbivores to be fully digest than plant based diet. Meat is however, easily broken down.
- Nevertheless, consuming animal protein is not necessary for humans. It's up to you what you do.
Hence, human dentition and length of the digestive tract are examples that suggest that humans are adapted to have an omnivorous diet.
