Diet categories in comparative proofs are typically narrow. The comparisons made are relatively simplistic, and the thinking process involved is also usually rather narrow: herbivores vs. carnivores vs. humans (and omnivores are sometimes added to the list). In referring to narrow thinking here, we mean that the comparative proofs neatly define their dietary categories in a narrow way, and ignore the fact that in nature, diets are usually not strict (i.e., "pure" diets are rare). The comparison of digestive system features comprises the second major component of many comparative proofs of diet.
