Did Neanderthals have language? Before trying to answer that, I should admit my bias: I’m team Neanderthal. As an anthropologist who studies our evolutionary cousins, I’ve seen plenty of evidence suggesting Neanderthals were competent, complex, social creatures. In light of their apparent cognitive abilities, I’m inclined to believe they had language.
But I can’t prove it, and no one else can, either. To date, there’s no evidence that Neanderthals developed writing, so language, if it existed, would have been verbal. Unlike writing, spoken languages leave no physical trace behind. Our words vanish as soon as they’re spoken.
The best researchers can do is to analyze Neanderthal fossils, artifacts and genes, looking for physical and cognitive traits considered necessary for language. And even after scrutinizing this same body of evidence, experts have come to different conclusions: Some say language is unique to our species, Homo sapiens; others contend Neanderthals also had the gift of gab. So, while the question remains up in the air, it’s not for lack of trying. Here’s all the evidence we have.
