Comparison between carnivores, herbivores and humans

When you look at the comparison between herbivores and humans, we compare much more closely to herbivores than meat eating animals. Humans are clearly not designed to digest and ingest meat.

• Meat-eaters: have claws
  Herbivores: no claws
  Humans: no claws

• Meat-eaters: have no skin pores and perspire through the tongue
  Herbivores: perspire through skin pores
  Humans: perspire through skin pores

• Meat-eaters: have sharp front teeth for tearing, with no flat molar teeth for grinding
  Herbivores: no sharp front teeth, but flat rear molars for grinding
  Humans: no sharp front teeth, but flat rear molars for grinding

• Meat-eaters: have intestinal tract that is only 3 times their body length so that rapidly decaying meat can pass through quickly
  Herbivores: have intestinal tract 10-12 times their body length.
  Humans: have intestinal tract 10-12 times their body length.

• Meat-eaters: have strong hydrochloric acid in stomach to digest meat
  Herbivores: have stomach acid that is 20 times weaker than that of a meat-eater
  Humans: have stomach acid that is 20 times weaker than that of a meat-eater

• Meat-eaters: salivary glands in mouth not needed to pre-digest grains and fruits.
  Herbivores: well-developed salivary glands which are necessary to pre-digest grains and fruits
  Humans: well-developed salivary glands, which are necessary to pre-digest, grains and fruits

• Meat-eaters: have acid saliva with no enzyme ptyalin to pre-digest grains
  Herbivores: have alkaline saliva with ptyalin to pre-digest grains
  Humans: have alkaline saliva with ptyalin to pre-digest grains
