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.
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.
Smarter Than a Three-Year-Old Child
A studies showed that:
•Pigs lead complex social lives that behaviorists once believed to be true only of primates;
•Mother pigs sing to their piglets while they are nursing;
•They excel at video games that would be hard for a young child, and sometimes better than the primates;
•Pigs have a good sense of direction, and can find their way home from long distances;
•They learn from watching one another;
•Pigs outsmart each other. One will often follow another pig to food before grabbing it away from him, and the pig who was tricked will change behaviors to reduce how many times it is tricked;
