According to a new study, our earliest ancestors smiled as a way to get some. A team of scientists claim that smiling was a key factor in our evolution, especially because it was a way to attract less-aggressive mates. Researchers focused on genetic samples from Neanderthals, which showed that gene mutations may have led humans to “self-select less aggressive mating partners.”
The researchers concluded from this that humans were selecting mates with “I probably won’t kill you” facial expressions more commonly than their ancestors. It has long been suspected that humans developed smiles to enhance mating options but this is thought to be the study with the first definitive evidence. Thanks for the leg-up in the bedroom, horny ancestors!
