Could Language Be Older Than Us?
October 11, 2024
Yes, language might be older than homo sapiens themselves. But, our language systems are unique to humans and stand apart from any form of animal communications and surpass even the abilities of our closest relatives like Neanderthals. While the Great Apes effectively use gestures, they do not approach the complexity of human language.
Language evolution, much like biological evolution, offers excellent insights into human history and cultural developments among different linguistically-related groups (or tribes). In fact, it is argued that over the past 200,000 years, language development has more significantly influenced our evolution more significantly than genetic changes.
However, language is referential, meaning we use it to share specific details about both people and objects, as well as their actions or locations. Words are the foundation of human communications as they shape how we think, how we interact with others, and how we perceive the world. Although most dictionaries contain about half a million words, just 100 words account for half of what we say.
Language is not a static construct but rather a dynamic one. As society changes, so does our language. It continuously evolves and adapts to new contexts and growing technologies. With the rise of technology and social media, we have seen an explosion of new vocabulary and linguistic norms emerge. New words are constantly being added while others fall out of use.
Did life evolve once or many times?
Language evolution and biological evolution share intriguing similarities. Life on our planet shares the same RNA and DNA, suggesting a common origin. Although it is possible that life could have evolved on Earth more than once, any of those origins have left no traces. Some studies suggest our ancestors might have spoken as far back as 500,000 years ago, potentially including the Neanderthals. Despite their large brains and ability to inhabit much of Eurasia, Neanderthals show little evidence of symbolic thinking or cultural achievements (art, tools or music) like those of contemporary Homo sapiens. This difference partly highlights why Homo sapiens flourished while Neanderthals did not, despite sharing over 99% of protein-coding gene sequences.
Distinct Language Evolution Theories
The origins of language have long been a fascinating yet debated topic among scholars. It's intertwined with human evolution, marked by evidence found in fossil records, archaeological findings, diverse languages today, language acquisition studies, and comparisons to animal communication systems, especially those of primates. Nonetheless, it is subjective, as most human languages were never recorded. So, language begins when we choose to define it, including:
Animal Vocal Language Theory – Theories behind animal vocal signals, such as primate calls, suggest these sounds function as an important form of language. Although vocalizations are not as complex as human languages, they do convey highly important information to others of the same species. Animal communications evolved to facilitate interactions around danger, food sources, and mating. But, non-human communication mainly involves repetitive actions aimed at specific goals rooted in instinctual behaviors.
Gestural Language Theory – Gestural language theory posits that human language emerged through gestures and hand movements, rather than vocal sounds. According to this theory, early humans could communicate with deliberate gestures and before the physical control over vocal expressions had fully evolved. Over time spoken language began developed alongside gestural language. Sign language today is a standalone communication, but gestures are used for emphasis and convey emotions.
Continuity Language Theory – The continuity language theory suggests that the complexity of human language couldn't have emerged all at once in its complete form. The continuity approach aligns with Darwinian principles, proposing that language evolved from simpler animal communication methods. Continuity theorists emphasize that language is an advanced evolutionary tool, evolving from earlier pre-linguistic systems, highlighting a continuous development rather than an abrupt emergence.
Discontinuity Language Theory – The discontinuity language theory suggests that language is a unique human trait that emerged suddenly during human evolution. Proponents of discontinuity argue that language's complexity implies it didn’t evolve from animals but arose from a genetic mutation in a single individual, highlighting its innate nature. This theory contrasts with the continuity perspective and suggests that language acquisition is a distinct and stepwise process through different life stages.
Genetic-Encoded Language Theory – The genetic-encoded language theory proposes that a network of genes, particularly the FOXP2 gene, plays a crucial role in our ability to speak and comprehend language. FOXP2 acts as a transcription factor, influencing the activity of up to 1,000 other genes. Much like music, language lacks a specific genetic form, yet humans have been inclined to develop both in various cultures. Notably, humans are unique among all life forms in their evolved capacity for spoken language.
Cultural Interactive Language Theory – The interactionist theory of language acquisition, also known as the cultural interactive language theory, is a sociocultural approach that highlights the crucial role of social interaction and cultural context in learning a language. This theory suggests that language development arises from the interplay between a child's innate biological abilities and their exposure to language within their environment that’s driven by an innate desire to connect with others.
Language has enabled humans to transmit complex information across generations for hundreds of thousands of years. Much of what we know today owes its existence to verbally communicated knowledge from the past, which became more intricate with the written word. Such linguistic ability has fostered the development of sophisticated cultural adaptations over time. Today, we are surrounded by advanced technologies, that often seem beyond our understanding in the beginning.

While the exact methods of early human communication remain uncertain, what we do know is that language continues to evolve, offering us endless possibilities for expression that will continue to advance with technology. But, multilingual lingual strategies in today’s global village require that you fully understand your organization’s linguistic and cultural needs.
