Evolution of Humans
Small Intestine
- If we compare a human's small intestine to a Carnivore's and an Herbivore's, we will find that a human and an herbivore have similar intestine lengths (this length would about 12 times the size of its body). A carnivore's small intestine stretches out to about three times its body length-this is because for an herbivore, the vitamins and minerals need to be extracted form the food before continuing with the digestive
Humans and herbivores must chew their food well because their digestive tract does not break down food as a carnivore's would-they can swallow it whole.
Human Jaw and Teeth
- Historically, the human jaw and teeth was originally shaped to consume berries and nuts. Over time as humans started to discover tools and consume meat, the jawline evolved. However, this does not mean humans were made to eat and digest meat.
The human jaw and teeth can easily be compared to an herbivore. Human and carnivore's ten to have flat molars, and these would be the most essential teeth in the mouth. Carnivore's have very sharp teeth with fewer molars.
Humans and herbivores can not open their mouths as much as carnivores.
