Physiological/Biological Anatomy of a (fruitarian) Human

Some evidence supporting our basic herbivorous natures:




Anatomical Chart Comparison of Human and Carnivore/Omnivor/Herbivore/Frugivore












































































































































































Carnivore Herbivore Omnivore Human
Facial Muscles Reduced to allow wide mouth gape. Well developed Reduced Well developed
Jaw Type Angle not expanded - Vertically mobile for biting or tearing. Expanded angle - Laterally mobile to allow chewing of food. Angle not expanded - Vertically mobile for biting or tearing. Expanded angle - Laterally mobile to allow chewing of food.
Jaw Joint Location On same plane as molar teeth Above the plane of the molars On same plane as molar teeth Above the plane of the molars
Jaw Motion Shearing; minimal side-to-side motion No shear; good side-to-side, front-to-back Shearing; minimal side-to-side motion No shear; good side-to-side, front-to-back
Major Jaw Muscles Temporalis Masseter and pterygoids Temporalis Masseter and pterygoids
Mouth Opening vs. Head Size Large Small Large Small
Teeth: Incisors Short and pointed Broad, flattened and spade shaped Short and pointed Broad, flattened and spade shaped
Teeth: Canines Long, sharp and curved Dull and short or long (for defense), or none Long, sharp and curved Short and blunted
Teeth: Molars Sharp, jagged and blade shaped Flattened with cusps vs complex surface Sharp blades and/or flattened Flattened with nodular cusps
Chewing None; swallows food whole Extensive chewing necessary Swallows food whole and/or simple crushing Extensive chewing necessary
Saliva No digestive enzymes - Acidic saliva for the digestion of animal protein; the enzyme ptyaline lowly developed salivary glands. Carbohydrate digesting enzymes - Alkaline salive pour a quick breakdown of food developed Salivary glands for pre-digestion.

Stomach Type Simple Simple or multiple chambers Simple Simple
Stomach Acidity Less than or equal to pH 1 with food in stomach pH 4 to 5 with food in stomach Less than or equal to pH 1 with food in stomach pH 4 to 5 with food in stomach

Although not exactly evidence of our fundamental fruitarian-ness, nevertheless still relevant and interesting.. I'd love to see an additional column labeled fruitarians..

Hello, Mango!

I'm working on a presentation on why fruit is the natural food for humans, would it be alright if I used these anatomical charts as examples?

Hi Rainskull,
sure, please send me your chart when it is done, and I will post it here too..

regards,
Mango.

Okay, thanks! I'll be sure to do that.
