Chew on This

In 1891, salesman William Wrigley, Jr. moved to Chicago to peddle soap. As an incentive to storeowners to stock his product, he offered free cans of baking soda. When he discovered that the baking soda was the more popular product, he began selling it and using chewing gum as an incentive. And when the gum proved to be the hot item, he became a very wealthy man.

He wasn’t the first person to crash onto the gum-selling scene, but he was possibly the savviest because Wrigley focused heavily on marketing. In 1915 he was sending free samples to homes all across the United States and had launched a series of newspaper ad campaigns with a wide range of claims about the benefits of chewing Wrigley’s gum while avoiding all those dastardly knock-offs.

Wrigley’s gum was sanitary, long-lasting, and refreshing. Kids loved it and it was good for teeth, stimulated appetite, and quenched thirst. It was soothing after a nice healthy smoke or it could take the place of one if you couldn’t indulge on the job. It eased digestion, relieved stress, and freshened breath. Not to mention soldiers in World War I probably couldn’t function without it. Allegedly.

And you know, some of these claims actually sort of hold up. But one advertisement I found particularly suspicious claims that early man sucked on rocks to moisten his mouth, because he didn’t have gum. Let me tell you, William Wrigley, Jr. might have been a genius when it came to advertising, but his anthropological research missed the mark.

An article published in December of 2019 in the journal Nature Communications squashes the Wrigley rock-sucking theory when it describes a wad of chewing gum that is about 5,700 years old.

Discovered in southern Denmark, this wasn’t the first ancient gum ever uncovered by paleontologists. It wasn’t the oldest either. There’s evidence that some of the people of northern Europe were chewing birch bark tar as far back as 9,000 years ago. The Ancient Mayans, too, chewed chicle from the sapodilla tree, as did the Aztecs who even had elaborate rules of conduct regarding it. For example, if an Aztec schoolgirl popped a chicle bubble in class, she had to immediately spit it out and probably got sent to the principal’s office.

What’s exciting about this recent gum discovery is that researchers managed to extract from it a complete human genome sequence. The chewer was a woman, though it’s not known why she might have been chewing this particular wad of birch bark. It’s possible she was looking for some pain relief from a toothache or perhaps she was softening it so she could stick it to the underside of a desk.

We do know she was a dark-skinned, blue-eyed, hunter-gatherer who’d eaten duck and hazelnuts for dinner and had been infected with the Epstein-Barr virus, aka mononucleosis, aka the “kissing disease.” Which might explain the gum.

Although I doubt her gum had quite the sweet taste or breath-freshening qualities of Wrigley’s. It probably wasn’t as sanitary, either. But it was surely better than sucking on a rock.
