Some years ago, a "pig-like" animal was found in Indonesia that had a split hoof -- but also had two stomachs so that it in fact did not function as a monogastric. (A regular pig is a monogastric -- one stomach.) This animal clearly is not identified in the Bible when those animals with one but not both signs of kosher are given. Presuming that the four animals mentioned all did exist in the North Africa/Middle East region at the time of establishing the kosher laws, their specific enumeration would simply represent the need to clearly delineate, which animals might be mistaken for kosher animals.
