Below is a list of differences that separates humans from carnivores.
All carnivores walk on all fours and us on two.
Carnivores have tails.
Carnivores have rough
tongues and ours smooth.
Carnivores have claws and lack of them makes ripping skin or flesh extremely difficult. We possess much weaker, flat fingernails instead.
Our opposable thumbs make us very well equipped to collect a meal of fruit in a matter of seconds. The claws of carnivores allow them to catch their prey in a matter of seconds as well. We could no easier catch and rip the skin or tough flesh of a deer or bear barehanded than a lion could pick mangos or bananas.
Humans usually have children one at a time. Carnivores typically give birth to litters.
Our convuluted colons are quite different in design from the smooth colons of carnivorous animals.
Our intestinal tracts measure roughly 12 times the length of our torsos (about 30 ft). This allows for the slow absorption of sugars and other water-borne nutrients from fruit. In contrast, the digestive tract of a carnivore is only 3 times the length of its torso. This is necessary to avoid rotting or decomposition of flesh inside the animal. The carnivore depends upon highly acidic secretions to facilitate rapid digestion and absorption in its very short tube. Still, the putrefication of proteins and the rancidity of fats is evident in their feces.
The multiple teats on the abdomens of carnivores do not coincide with the pair of mammary glands on the chest of humans.
Humans spend roughly two thirds of every 24-hour cycle actively awake. Carnivores typically sleep and rest from 18 to 20 hours per day and sometimes more.
Most carnivores can digest microbes that would be deadly for humans, such as that cause botulism.
Our sense of vision responds to the full spectrum of color, making it possible to distinguish ripe from unripe fruit at a distance. Meat eaters do not typically see in full color.
Fruit is in scale to our food requirements. It fits our hands. A few pieces of fruit is enough to make a meal, leaving no waste. Carnivores typically eat the entire animal when they kill it.
Should we need to drink water, we can suck it with our lips, but we cannot lap it up. Carnivores’ tongues protrude outward so they can lap water when they need to drink.
We have discoid-style placenta, whereas the carnivores have zonary placentas.
Carnivores manufacture their own vitamin C. For us, vitamin C is an essential nutrient that we must get from our food.
Our ability to grind our food is unique to plant eaters. Meat eaters have no lateral movement in their jaws.
Mammalogists use a system called the “dental formula” to describe the arrangement of teeth in each quadrant of the jaws of an animal’s mouth. This refers to the number of incisors, canines, and molars in each of the four quadrants. Starting from the center and moving outward, our formula, and that of most anthropoids, is 2/1/5. The dental formula for carnivores is 3/1/5-to-8.
The molars of a carnivore are pointed and sharp. Ours are primarily flat, for mashing food. Our “canine” teeth bear no resemblance to true fangs. Nor do we have a mouth full of them, as a true carnivore does. I am reminded of one of Abraham Lincoln’s favorite retorts: “If you counted a sheep’s tail as a leg, how many legs would it have?” Invariably, people would answer, “five.” To which Lincoln would respond: “Only four. Counting the tail as a leg doesn’t make it one.”
TOLERANCE FOR FATS
We do not handle more than small quantities of fat well. Meat eaters thrive on a high-fat diet.
SALIVA AND URINE pH
All of the plant-eating creatures (including healthy humans) maintain alkaline saliva and urine most of the time. The saliva and urine of the meat eating animals, however, acidic.
Carnivores thrive on a diet of acid-forming foods, whereas such a diet is deadly to humans, setting the stage for a wide variety of disease states. Our preferred foods are all alkaline-forming.
STOMACH ACID pH
The pH level of the hydrochloric acid that humans produce in their stomachs generally range about 3 to 4 or higher but can go as low as 2.0. (0 = most acidic, 7 = neutral, 14 = most alkaline). The stomach acid of cats and other meat eaters can be in the 1+ range and usually runs in the 2s. Because the pH scale is logarithmic, this means the stomach acid of a carnivore is at least 10 times stronger than that of a human and can be 100 or even 1,000 times stronger.
True carnivores secrete an enzyme called uricase to metabolize the uric acid in flesh. We secrete none and so must neutralize this strong acid with our alkaline minerals, primarily calcium. The resulting calcium urate crystals are one of the many pathogens of meat eating, in this case giving rise to or contributing to gout, arthritis, rheumatism, and bursitis.
Our digestive enzymes are geared to make for easy fruit digestion. We produce ptyalin-also known as salivary amylase-to initiate the digestion of fruit. Meat-eating animals do not produce any ptyalin and have completely different digestive enzyme ratios.
The glucose and fructose in fruits fuel our cells without straining our pancreas (unless we eat a high-fat diet). Meat eaters do not handle sugars wells. They are prone to diabetes if they eat a diet that is predominated by fruit.
Humans have different bacterial colonies (flora) living in their intestines than those found in carnivorous animals. The ones that are similiar, such as lactobacillus and e. coli are found in different ratios in the plant eaters’ intestines as compared to those of the carnivores.
Carnivores have proportionately larger livers in comparison to their body size than humans.
We are the most particular of all creatures about the cleanliness of our food. Carnivores are the least picky, and will eat dirt, bugs, organic debris, and other items along with their food.
Our mouths water at the sights and smells of the produce market. These are living foods, the source of our sustenance. But the smell of animals usually puts us off. Meat eaters’ mouths water at the sight of prey, and they react to the smell of animals as though they sense food.
