Humans are far different from another other land mammal. Genetically we may be close to chimps and other primates, but we share only a few things in common with them. Humans have the ability to run longer distances than any other land mammal. From a migratory perspective, we are similar only to birds.

Our uniqueness is why I believe that we are not omnivores, but we evolved primarily on a single food. It is a situation like the koala bear, or the panda bear. Without this food we are prone to diseases and early death.
