A recent study examining human DNA suggests that humans may have had the ability to speak as far back as 135,000 years ago. The research, led by Shigeru Miyagawa from the Massachusetts Institute of Technology (MIT), used genetic data to estimate when early human groups began to split geographically. This separation, the researchers believe, can offer insights into when the first spoken language might have emerged. The study reviewed fifteen genetic studies from the past eighteen years, analyzing mitochondrial DNA, the Y chromosome, and full genome sequences. The findings suggest that Homo sapiens formed a single population about 135,000 years ago before dispersing across the globe. This implies that the biological capacity for language might have existed before this major geographic split. According to Miyagawa and his team, while humans may have had the physical ability to speak 135,000 years ago, the development of a fully structured language system likely took tens of thousands of years more. Evidence from archaeology shows that by 100,000 years ago, humans were creating objects with symbolic meaning, such as red ochre pigments used to decorate shells and tools, and intricate carvings on bones and stones. These artifacts suggest that language was becoming an important tool for communication. The researchers argue that this evolution of language helped humans transmit knowledge more effectively, strengthen group unity, and promote cooperation. Not all scientists agree with the study's conclusions. Some believe that language may be much older than 135,000 years. Research into the anatomy of early human relatives, such as Homo heidelbergensis, suggests that these species, which lived around 600,000 years ago, may have had the vocal abilities necessary for speech. Others propose that even earlier hominids, like the Australopiths, who lived over two million years ago, might have used basic forms of communication. Some theories also suggest that language developed gradually over time, evolving in small steps as communication needs became more complex. One of the main challenges in studying the origins of language is the lack of physical evidence. Unlike tools or artwork, language does not leave behind fossils or other tangible remains. While genetics and archaeology can provide indirect clues, they cannot yet offer definitive proof of when language first appeared. This uncertainty means that while the study provides a new perspective, the exact timeline of language's emergence remains an open question in the scientific community.
