Reply #63: The reason we non't have a lot of adaptations for meat-eating...

[Odin2005]

...is that it is only in the last 2.5 million years that meat has been an important part of our diet (though pre-Homo hominid species may of scavenged ocasionally), first by scavenging during the dry season, then by hunting. We are omnivores that just recently evolved from herbivores, which is why we retain many herbiviourous physiological characteristics. That vegans have to so carefully manage thier diet to get enough essential amino acids is proof that total herbivory is unatural. Carefully managine of a diet was a luxury our Stone Age ancestors did not have, they ate what they found, or starved.
