Some scientists have theorized that it only became physically possible to speak a wide range of essential vowel sounds when our vocal anatomy changed with the rise of Homo sapiens some 300,000 years ago. This theoretical timeline means that language, where the brain associates words with objects or concepts and arranges them in complex sentences, would have been a relatively recent phenomenon, developing with or after our ability to speak a diverse array of sounds.
But a comprehensive study analyzing several decades of research, from primate vocalization to vocal tract acoustic modeling, suggests the idea that only Homo sapiens could physically talk may miss the mark when it comes to our ancestors’ first speech—by a staggering 27 million years or more.
