This is Britt and you’re listening to Radical Wellness’s segment Fun Fact Friday. Have you ever noticed that we are the only species with chins? Chimpanzees and gorillas lower jaws slope back from their teeth, so they don’t have chins. Even our ancient ancestors Homo Eructus had sloped back jaws. Nethanderthal jaws did slope back, but they ended at a vertical lane. So still, no jaw. It wasn’t until our species, the modern human, that chins really became a thing. Some scientists have speculated that we have jaws to help the chewing process, while other scientists are still looking for answers. The truth is, no one really understands the purpose of the chin….yet. So when someone asks you what makes you human, the answer is a chin.
