A roadblock humans have in deciphering intelligence in animals is that we can't help but assume the smartest ones must resemble us. Clearly, nobody told that to the pig.

How is intelligence measured? After all, even people can be intelligent or extraordinary in many ways. Some excel at math, and some are gifted linguists. Others fail in the academic arena entirely, and shine as masterful artists. One way to measure intelligence is based on the ability to solve problems.

The associations people have made with the word, ‘pig’, are less than glamorous. In fact, there are downright negative connotations attached to the word, which is why we use it to insult people. But, let’s put aside our preconceived ideas of what we think a pig is, let’s take a look at who they really are.

Pigs have been touted as the smartest, and the cleanest domestic animals in the world. The phrases, “sweat like a pig” or “smell like a pig”, may come to mind. But, consider that pigs don’t have sweat glands, and therefore, can’t sweat (except on the very ends of their snouts). The lack of sweat glands means lack of odor - affording no credibility to either statement.

To compensate for the lack of a natural way to bring their body temperature down, pigs seek out water or mud. Pigs rolling in mud may look uncouth, but they are actually being quite smart. The mud not only keeps them cool, but keeps biting pests at bay, and prevents sunburn.
As Smart as the Primates

Intelligence research was done with pigs in the 1990s. One of the experiments was to train the pigs to move the cursor on a video screen with their snouts. When the pigs used the cursors again, they were able to distinguish between the scribbles they already knew, and the scribbles they were seeing for the first time. The pigs learned this skill as fast as the chimpanzees.

All species of pig are smarter than dogs, and capable of abstract representation. “They can hold an icon in their mind, and remember it at a later date,” says Professor Stanley Curtis of Penn State University, who discovered that pigs dominate at video games with joy sticks. Curtis goes on to say, “Pigs are able to focus with an intensity I have never seen in a chimp.”
