Chimpanzees for example will purposefully mislead troop members away from a tasty food source and then return later to gobble it solo.
Researchers have discovered that the more conniving a primate species, the bigger its brain. (It therefore makes sense that with our giant brains, humans are veritable founts of hogwash.) The faculties of memory and abstraction needed to mince language and appearance so as to deceive require a lot of brainpower, researchers have learned. [10 Things You Didn’t Know About the Brain]

A 2005 study showed that liars had 22 percent more “white matter” than average, as well as about 14 percent less “gray matter.” The former acts like wiring in the brain, while gray matter cells
