In stark contrast to biblical literalism's simplistic and contradictory story, recent research provides a very different picture of the origins of human language. According to Bible literalists, there are two versions of how languages come about. In the first, the descendants of each of the sons of Noah spoke different languages; in the second, language originated just five generations after the mythical global flood, when the human population — miraculously expanded from eight closely related survivors - grew large enough to undertake a massive construction project. Supposedly, this project so alarmed God that he intervened by 'confounding their tongues' to stop their cooperation.
In contrast to these Bible stories which compete for the most ludicrous and unlikely, scientists led by the Massachusetts Institute of Technology (MIT) have recently suggested that human language actually evolved between 100,000 and 135,000 years before creationists claim the universe itself existed. v
What is the current consensus on the time and place of the origins of language in humans?The findings of the MIT group are published, open access, in the journal Frontiers in Psychology and are explained by Peter Dizikes in MIT News:There is currently no clear scientific consensus regarding the exact timing and location of the origins of human language, primarily because language leaves no direct fossil evidence. However, there is broad agreement around certain key points:
Timing of Language Origin:
- General timeframe: Most researchers propose that fully-developed spoken language originated between 50,000 and 200,000 years ago, during the late Middle or early Upper Palaeolithic period, associated with anatomically modern Homo sapiens.
- Genetic clues: Genetic evidence, particularly the emergence of the FOXP2 gene mutation (linked to speech and language capability), suggests language capacity existed at least around 150,000–200,000 years ago.
- Cultural and archaeological indicators: A notable increase in symbolic behaviour, such as sophisticated art, toolmaking, and ritual practices approximately 40,000–70,000 years ago (often referred to as the "cognitive revolution"), is widely viewed as indirect evidence of fully developed linguistic capabilities. However, many linguists argue for a much earlier, more gradual development extending back hundreds of thousands of years.
Place of Origin:
- Africa hypothesis: The widely supported "Out of Africa" theory of modern human evolution implies that language, like other uniquely human traits, likely emerged first in Africa, associated with early Homo sapiens populations around 150,000–200,000 years ago.
- Multiple origins or dispersal: While most linguists and paleoanthropologists favour an African origin due to genetic and fossil evidence, some researchers have proposed language capabilities could have evolved independently or spread quickly as humans migrated. However, the single-origin hypothesis currently dominates.
Mechanism of Origin:
- Gradual evolution: The prevailing view today is that language evolved gradually through incremental cognitive, anatomical, and social adaptations, rather than appearing abruptly.
- Social complexity: Most researchers believe language emerged alongside increasing social complexity, facilitating cooperation, teaching, and cultural transmission, which in turn provided strong evolutionary advantages.
Current Scientific Consensus:
- No direct fossil evidence means pinpointing exact dates or locations remains speculative.
- Broad consensus: Language emerged gradually, probably in Africa, between 50,000–200,000 years ago, closely tied to the cognitive evolution of anatomically modern humans.
In summary, while the exact details remain debated, the dominant scientific consensus positions the origin of human language firmly within the evolutionary context of anatomically modern Homo sapiens in Africa, sometime around or shortly before humans began their global migrations.
When did human language emerge?
A new analysis suggests our language capacity existed at least 135,000 years ago, with language used widely perhaps 35,000 years after that.
It is a deep question, from deep in our history: When did human language as we know it emerge? A new survey of genomic evidence suggests our unique language capacity was present at least 135,000 years ago. Subsequently, language might have entered social use 100,000 years ago.
Our species, Homo sapiens, is about 230,000 years old. Estimates of when language originated vary widely, based on different forms of evidence, from fossils to cultural artifacts. The authors of the new analysis took a different approach. They reasoned that since all human languages likely have a common origin — as the researchers strongly think — the key question is how far back in time regional groups began spreading around the world.
The logic is very simple. Every population branching across the globe has human language, and all languages are related. [Based on what the genomics data indicate about the geographic divergence of early human populations] I think we can say with a fair amount of certainty that the first split occurred about 135,000 years ago, so human language capacity must have been present by then, or before.

The paper, “Linguistic capacity was present in the Homo sapiens population 135 thousand years ago,” appears in Frontiers in Psychology. The co-authors are Miyagawa, who is a professor emeritus of linguistics and the Kochi-Manjiro Professor of Japanese Language and Culture at MIT; Rob DeSalle, a principal investigator at the American Museum of Natural History’s Institute for Comparative Genomics; Vitor Augusto Nóbrega, a faculty member in linguistics at the University of São Paolo; Remo Nitschke, of the University of Zurich, who worked on the project while at the University of Arizona linguistics department; Mercedes Okumura of the Department of Genetics and Evolutionary Biology at the University of São Paulo; and Ian Tattersall, curator emeritus of human origins at the American Museum of Natural History.
The new paper examines 15 genetic studies of different varieties, published over the past 18 years: Three used data about the inherited Y chromosome, three examined mitochondrial DNA, and nine were whole-genome studies.
All told, the data from these studies suggest an initial regional branching of humans about 135,000 years ago. That is, after the emergence of Homo sapiens, groups of people subsequently moved apart geographically, and some resulting genetic variations have developed, over time, among the different regional subpopulations. The amount of genetic variation shown in the studies allows researchers to estimate the point in time at which Homo sapiens was still one regionally undivided group.
Miyagawa says the studies collectively provide increasingly converging evidence about when these geographic splits started taking place. The first survey of this type was performed by other scholars in 2017, but they had fewer existing genetic studies to draw upon. Now, there are much more published data available, which when considered together point to 135,000 years ago as the likely time of the first split.
The new meta-analysis was possible because “quantity-wise we have more studies, and quality-wise, it’s a narrower window [of time],” says Miyagawa, who also holds an appointment at the University of São Paolo.
Like many linguists, Miyagawa believes all human languages are demonstrably related to each other, something he has examined in his own work. For instance, in his 2010 book, “Why Agree? Why Move?” he analyzed previously unexplored similarities between English, Japanese, and some of the Bantu languages. There are more than 7,000 identified human languages around the globe.
Some scholars have proposed that language capacity dates back a couple of million years, based on the physiological characteristics of other primates. But to Miyagawa, the question is not when primates could utter certain sounds; it is when humans had the cognitive ability to develop language as we know it, combining vocabulary and grammar into a system generating an infinite amount of rules-based expression.
Human language is qualitatively different because there are two things, words and syntax, working together to create this very complex system. No other animal has a parallel structure in their communication system. And that gives us the ability to generate very sophisticated thoughts and to communicate them to others.
Professor Shigeru Miyagawa.
This conception of human language origins also holds that humans had the cognitive capacity for language for some period of time before we constructed our first languages.
Language is both a cognitive system and a communication system. My guess is prior to 135,000 years ago, it did start out as a private cognitive system, but relatively quickly that turned into a communications system.
Professor Shigeru Miyagawa.
So, how can we know when distinctively human language was first used? The archaeological record is invaluable in this regard. Roughly 100,000 years ago, the evidence shows, there was a widespread appearance of symbolic activity, from meaningful markings on objects to the use of fire to produce ochre, a decorative red color.
Like our complex, highly generative language, these symbolic activities are engaged in by people, and no other creatures. As the paper notes, “behaviors compatible with language and the consistent exercise of symbolic thinking are detectable only in the archaeological record of H. sapiens.”
Among the co-authors, Tattersall has most prominently propounded the view that language served as a kind of ignition for symbolic thinking and other organized activities.
Language was the trigger for modern human behavior. Somehow it stimulated human thinking and helped create these kinds of behaviors. If we are right, people were learning from each other [due to language] and encouraging innovations of the types we saw 100,000 years ago.
Professor Shigeru Miyagawa.
To be sure, as the authors acknowledge in the paper, other scholars believe there was a more incremental and broad-based development of new activities around 100,000 years ago, involving materials, tools, and social coordination, with language playing a role in this, but not necessarily being the central force.
For his part, Miyagawa recognizes that there is considerable room for further progress in this area of research, but thinks efforts like the current paper are at least steps toward filling out a more detailed picture of language’s emergence.
Our approach is very empirically based, grounded in the latest genetic understanding of early homo sapiens. I think we are on a good research arc, and I hope this will encourage people to look more at human language and evolution.
Professor Shigeru Miyagawa.
Recent genome-level studies on the divergence of early Homo sapiens, based on single nucleotide polymorphisms, suggest that the initial population division within H. sapiens from the original stem occurred approximately 135 thousand years ago. Given that this and all subsequent divisions led to populations with full linguistic capacity, it is reasonable to assume that the potential for language must have been present at the latest by around 135 thousand years ago, before the first division occurred. Had linguistic capacity developed later, we would expect to find some modern human populations without language, or with some fundamentally different mode of communication. Neither is the case. While current evidence does not tell us exactly when language itself appeared, the genomic studies do allow a fairly accurate estimate of the time by which linguistic capacity must have been present in the modern human lineage. Based on the lower boundary of 135 thousand years ago for language, we propose that language may have triggered the widespread appearance of modern human behavior approximately 100 thousand years ago.In conclusion, the researchers say:
1 Introduction
More than any other trait, language defines us as human. Yet there is no clear agreement on when this crucial feature emerged in our evolution. Some who have studied the archaeological record suggest that language emerged in our lineage around 100 thousand years ago (kya) (Tattersall, 2012, 2017, 2018; Wadley, 2021), while others have claimed that some form of language preceded the emergence of modern humans (Albessard-Ball and Balzeau, 2018; Botha, 2020). Indeed, it has been argued [e.g., by Progovac (2016) and Dediu and Levinson (2018)] that language is not uniquely the property of the lineage that produced H. sapiens. Here we accept the reasoning of that behaviors compatible with language and the consistent exercise of symbolic thinking are detectable only in the archaeological record of H. sapiens (Tattersall, 2012; Berwick et al., 2013; Berwick and Chomsky, 2016), and approach the issue of the antiquity of language in our species by showing that, although it is not yet possible to identify the time when a linguistic capacity emerged, genomic evidence allows us to establish with reasonable certainty the latest point at which it must have been present in early H. sapiens populations.
Over the past 15 years, numerous studies have addressed the question of exactly when the first division occurred in the original stem population of early H. sapiens. While those studies do not tell us exactly when language emerged, they allow us to make a reasonable estimate of the lower boundary of the possible time range for this key occurrence. H. sapiens emerged as an anatomically distinctive entity by about 230kya (Vidal et al., 2022). Sometime after that speciation event, the first division occurred, with all descendant populations of that division having full-fledged language. From this universal presence of language, we can deduce that some form of linguistic capacity must have been present before the first population divergence. If the linguistic capacity had emerged in humans after the initial divergence, one would expect to find modern human populations that either do not have language, or that have some communication capacity that differs meaningfully from that of all other human populations. Neither is the case. The 7,000 or so languages in the world today share striking similarities in the ways in which they are constructed phonologically, syntactically, and semantically (Eberhard et al., 2023).
Genomic studies of early H. sapiens population broadly agree that the first division from the original stem is represented today by the Khoisan peoples of Southern Africa (Schlebusch et al., 2012). This conclusion was reached early on Vigilant et al. (1989), Knight et al. (2003), Tishkoff et al. (2007), and Veeramah et al. (2012), and it has more recently been bolstered by studies using newer genomic techniques (Fan et al., 2019; Lorente-Galdos et al., 2019; Schlebusch et al., 2017; Schlebusch et al., 2020; Pakendorf and Stoneking, 2021). The term “Khoisan” refers to a bio-genetic affiliation that is linked both to a proposed ancestor-group and to some modern peoples, living in present-day South Africa, who include modern speakers of the Khoe-Khwadi, Tuu, and Ju-ǂHoan languages that have some genetic affiliation to the first divergence of the human population (Güldemann and Sands, 2009; du Plessis, 2014). It follows that, if we can identify when the first division occurred, we can with reasonable certainty consider that date to define the lower boundary of when human language was present in the ancestral modern human population. Based on the results of studies focusing on whole genome single nucleotide polymorphisms (SNPs), we estimate that this first division occurred at approximately 135kya. 1
Huybregts (2017) was the first to attempt to pinpoint the timing of the first division in this way. Although he suggested a date of ~125kya, close to our estimate of ~135kya, his estimate was necessarily based on a fairly narrow set of studies showing a remarkably variable range. The studies he examined ranged from the clearly implausible 300kya (Scally and Durbin, 2012), to 180kya (Rito et al., 2013) and as little as 100kya (Schlebusch et al., 2012). Pakendorf and Stoneking (2021) later listed several studies proposing that the first division was older than 160kya (Fan et al., 2019; Lorente-Galdos et al., 2019; Schlebusch et al., 2020), along with four others, from 140 to 110kya, that overlapped with the range suggested by Huybregts (Gronau et al., 2011; Veeramah et al., 2012; Mallick et al., 2016; Song et al., 2017). Several newer studies now allow us to approach the age of the first division with greater precision.
4 The picture that emerges
Based on the recent genetic studies of early H. sapiens, we have pinpointed approximately 135kya as the moment at which some linguistic capacity must have been present in the human population. Looking forward from this event, modern human behaviors such as body decoration and the production of ochre pieces with symbolic engravings appeared as normative and persistent behaviors around 100kya. We believe that the time lag implied between the lower boundary of when language was present (135kya) and the emergence of normative modern human behaviors across the population suggests that language itself was the trigger that transformed nonlinguistic early H. sapiens (who nonetheless already possessed “language-ready” brains acquired at the origin of the anatomically distinctive species) into the symbolically-mediated beings familiar today. This development of the most sophisticated communication device in evolution allowed our ancestors to accelerate and consolidate symbolically-mediated behaviors until they became the norm for the entire species.

It appears that the evolution of language in humans followed a familiar evolutionary pattern. Genetic mutations, including those affecting the FOXP2 gene—which influences brain development and vocal control—provided cognitive advantages, opening new opportunities for natural selection. This genetic foundation set human evolution onto a new trajectory, much like how feathers, originally evolved for insulation or display in dinosaurs, eventually led to powered flight in birds.
In contrast, simplistic explanations—such as the Bible's depiction of Noah's descendants rapidly diverging into different languages (Genesis 10–11), or a deity magically imposing language barriers to thwart human cooperation at Babel (Genesis 11)—reflect limited imagination and a profound misunderstanding of how closely related languages evolve geographically.
Today, science provides a coherent and evidence-based explanation, emphasizing gene-culture co-evolution and language divergence within geographically dispersed and partially fragmented human populations.
