Meat lover logic
Re: "Strange logic", (PostBag, Jan 9).
As much I hate to recognise it, it seems that Eric Bahrt has a point in his endless crusade against meat-eating: shall we be carnivorous, herbivorous or omnivorous, also recently fought by numerous PostBag contributors.
Allow me to quote sinergiaanimalinternational.org:
Our teeth, jaws, and nails: Carnivores have mouths that open wide, and their jaws are simply hinged. Humans, on the other hand, have the smaller mouths and fleshier lips characteristic of herbivores. Further, the joint of our jaw is more akin to that of a standard herbivore than that characteristic of carnivores. Our nails are also the blunt, flat variety of herbivores rather than the sharp, long claws of carnivores.
Stomach acidity: The acidity of the human stomach is similar to that of herbivores. Both humans and herbivores have a mildly acidic stomach pH between 4 and 5 when food is present, whereas carnivores have a far more acidic stomach pH of 1 or less when digesting food.
Intestinal length: The length of the human intestines is much more like that of herbivorous animals than that of carnivores. Humans tend to have intestines that are 10 to 11 times their body length. Herbivores, like humans, have long intestines of 10 to 12 or more times their body length -- to provide ample space for the digestion of plant matter. Carnivores, however, have short intestines of only three to six times their body length, accounting for only a small amount of the total capacity of their digestive system.
How did humans end up eating meat? Scientists believe that it was climate change that originally caused the shift towards meat eating. As the earth grew warmer between 2.5 and 2.6 million years ago, our early ancestors were forced to shift away from a diet focused solely on plants to one that included animal protein as well. Even once our early ancestors began eating meat, they primarily scavenged the leftovers of larger predators instead of hunting for themselves.
But, and I repeat but, today the consensus is that humans are really omnivorous, which means that tonight I will eat my hamburger with a big smile!
