The Development of Language
C. George Boeree
Language began with the simple association of certain vocalisms with
objects ("dog"), then actions ("go"), and finally qualities ("hot").
Children would learn these associations from their elders, rather
than invent a new vocabulary with every generation. But once the
idea of association was realized, I am certain that the numbers of
these proto-words increased rapidly.
Then, just like children do, primitive humans began putting two
vocalisms together: "dog go", "see dog", "big dog, "dog('s) bone",
etc. And then the strings of vocalisms expanded to three: "I see
dog", "big dog go", etc. And so forth. What passed for syntax was
the simple ordering of the words, probably in order of importance.
Perhaps pronouns date from this era: me, you, this, that. This
probably was the extent of language for millenia.
My guess is that this began early in our evolution, pre-Homo, and
did not require any specialized area of the brain, although, of
course, it would involve the auditory cortex and the motor areas
devoted to vocalization.
But translating the multidimensional perceived world into a linear
set of vocalizations would make specialization of parts of the
cortex advantageous, and we may have started to differentiate the
Wernicke's and Broca's areas from the auditory and motor cortices.
As language became an increasingly important part of human survival
and prosperity, this specialization would be selected for.
At some point, humans invented some real syntax in the form of set
sequences of words: Subject-object-verb, with adjectives before
nouns, and postpositions; or maybe subject-verb-object, with
adjectives after nouns, and prepositions. Perhaps each group
of humans adopted their own preferred sequences.
At some point, regular words began to be used as particles with more
abstract meanings. For example, "head" may have been used for
"top", "on", and "above", and "follow" for "after", etc. Perhaps a
word like "finish" was used to mark a verb as past perfect.
Expressive vocalisms became other particles, such as using "huh?" to
create questions. Some adjectives began to modify verbs as well as
nouns. You can still see the remnants of these processes in a number
Some of these particles may have become attached to more significant
words as clitics, affixes, and even inflections. The syntax and,
now, morphology used by parents were passed on to their children by
example, and the children could then expand these examples by
generalizing the rules to cover novel situations and needs.
Eventually, humans came up with the idea of imbedding one sentence
inside another, along with special particles like "which", "that",
"if", "because", and so on. And at some point, they had the idea
that one could use pronouns and proverbs to interconnect the actors
and acts in these clauses.
Finally, we developed words and ways of combining words to express
abstract ideas, and to use these new words to form ever more complex
theories about ourselves and the world. With syntax, morphology,
clauses, and abstractions, brain size would become increasingly
significant as a determiner of survival and reproduction, and modern
humans would be well on their way to developing civilization.
Was there ever a single "mother language" from which all others
descend? Probably not. The idea of communicating with vocalizations
must have spread like wildfire among our pre-Homo ancestors, and was
then, presumably, elaborated into true language by our Homo sapiens
ancestors. It is possible that there was originally only one tribe
of Homo sapiens, but language changes relatively easily, and there
were probably already multiple languages that were not
interintelligible before we even expanded beyond Africa. Again, when
that expansion finally happened, there may have been only a few
pioneering tribes, each with their own language, who in turn began
The idea that we all shared one language is very interesting, even
romantic, but it is pretty clear, all objections to the contrary,
that going back further than, say, 10,000 years is about as far as
