If we were to take a scientific look at humor, at least as we understand it today, we'd see that it did not just randomly appear out of nowhere; according to Chris Robert, who received his Ph.D. from the University of Illinois in Industrial/Organizational Psychology, it is probably the result of millions of years of evolution.
"In its earliest forms, humor likely evolved from panting and grunting that occurred during non-serious fighting or other forms of play, or during social 'down time' among our ancient primate ancestors," Robert wrote in Psychology Today.
"Although there was nobody there to document the events with their cell phone, or to upload the video to YouTube, we can extrapolate from similar sounds and behaviors observed among modern primates. Over time, these sounds likely evolved into more specialized vocal sounds that we might now recognize as early forms of laughter... Early hominids that could make those early laughter sounds, and those who had the mental capacity to distinguish between laughter and non-laughter sounds, likely benefitted from stronger bonds with other individuals within their group."

To this day, society judges people on their physical appearance, if our eyes could see souls instead of bodies, Mary Ann would have been the most beautiful woman in the world. "
Robert suggests thinking of it like this: 'funny' primates or early hominids were those who could make sounds that communicated the message, 'We're safe and happy now: Everybody relax and pick some bugs off each other. Eat them if you're hungry.'
"They could also identify those sounds when others in their social group made them, taking the context into account, and could respond appropriately," he explained. "'Non-funny' primates didn't pick up on the signals. They would get angry with others who were only trying to play, and might lash out inappropriately—this is not a good strategy for making friends or finding mates."
In today's world, these are the people at work you 'accidentally' forget to invite to a colleagues night out.
"Similarly, primates who mistook danger vocalizations for play vocalizations were the ones who let their guard down, showed up in the clearing with their rubber chicken and Groucho glasses, and became lunch for a prowling saber-toothed tiger."
Becoming someone's lunch makes it exceedingly difficult to pass on your genes. But those who could make and identify laughter sounds in others were probably more likely to reproduce and pass on genes too. Which helped their offspring create and/or distinguish between play and not-play sounds.
"Those with mutations that allowed them to make even better sounds, and detect the meaning of those sounds, were even more likely to form strong bonds, survive, and pass on their genes, and so on," Robert added.
Fast forward a million years and humor has developed in the human species as something much more subtle.
"At its core, humor involves the ability to detect and to create incongruities," the psychologist said. "Among our ancient ancestors, the incongruity might have been between behavior that looked like fighting, but which was understood as non-serious or play behavior because it was accompanied by cues such as laugh-like sounds. But as our cognitive abilities have progressed, in parallel with language abilities, so too has our ability to create and appreciate more complex and sophisticated incongruities."
Just as our ancient ancestors evolved to enjoy the simple play behaviors, early grunting-laughing sounds, and bonding that occurred throughout this process, we too still enjoy a good poop joke. Even though the humor that we appreciate tends to involve much more abstract and symbolic meaning than with physical play, the impact is no less real.
