Language Origins
When did humans develop language? Are the origins of language lost in the mist of time, or does science provide us with some clues as to when, how, and why this ability appeared in humans?
It seems that language appeared from nowhere, since no other species has anything resembling human language. However, other animals do possess basic systems for perceiving and generating sounds that enable them to communicate. These systems may have been in place before the appearance of language.
In the six million years since apes and humans evolved from a common ancestor, language emerged only in the human line, along with all the necessary brain structures for encoding thoughts into sounds and transmitting them to others members of the species for decoding.
What were the first steps toward developing language?
Dr. Derek Bickerton of the University of Hawai’i argues that humans may have been speaking a precursor of language (words without grammar) some two million years ago. He suggests that language developed some 120,000 years ago when humans left the forest and started to forage and hunt in the savanna. To communicate to others what they found, they needed to develop context-free vocal symbols, for instance, a general word for lion. By context-free is meant that the same word could be used in different contexts, such as “The lion is big,” or “The lion is hiding in the bushes,” or “Beware of the lion.” In this way, early hominids could have taken the first steps toward language. Language also provided a means to engage in communal activities, such as hunting, and to transmit knowledge, such as tool-making. Ability to communicate through language created an advantage that spread quickly through the population.
The faculty for language may be coded in our genes, waiting for scientists to identify the genetic program responsible for this uniquely human ability.
The Range of World Languages
How many languages are spoken in the world?
As you look at the map of the continents, imagine that by some estimates there are roughly 6,800 languages spoken on this planet. 96% of them are spoken by a mere 4% of the world’s population. The exact number of languages may never be determined exactly.
Where are these languages spoken?
Ethnologue estimates that 2,200 are spoken in Asia, 2,060 in Africa, 1,300 in the Pacific, 1,000 in the Americas, and 230 in Europe.
Which countries have the greatest number of languages?
Papua-New Guinea 832
Indonesia 731
Nigeria 515
India 400
Mexico 295
Cameroon 286
Australia 268
Brazil 234
Half of the world’s languages are spoken in only eight countries.
Why is the exact number of languages difficult to determine?
Firstly, we don’t know enough about many of the languages. Linguistic surveys in many parts of the world are incomplete. Some languages have yet to be discovered. Lots of languages have not been adequately described. This is the case with many languages of Asia, Africa, Australia, and the Americas.
Secondly, criteria of national identity and mutual intelligibility may not coincide. In some cases, political criteria outweigh linguistic considerations. For instance, Swedish, Danish, and Norwegian are mutually intelligible (linguistic criteria) but since they are spoken in different countries (political criteria), they are considered to be three separate languages. On the other hand, many dialects of Chinese are mutually unintelligible, but are considered to be varieties of the same language because they are spoken in the same country and because they share the same writing system.
Human voices in cosmic space
25 years after their 1977 launch, the twin Voyager 1 and 2 spacecraft are twice as distant from Earth as Pluto, and speeding outward into interstellar space at 38,000 miles per hour. Both spacecraft are still sending scientific information about their surroundings through the Deep Space Network.
Voyager carries a message on a phonograph record, a 12-inch gold-plated copper disk, that contains sounds and images portraying the diversity of life and culture on Earth. The contents of the record were selected for NASA by a committee chaired by Carl Sagan. They assembled images, a variety of natural sounds, musical selections from different cultures and eras, and spoken greetings from Earth in fifty-five languages including several dead ones. Instructions use symbolic language to describe the origin of the spacecraft and to explain how the record is to be played.
It will be forty thousand years before the Voyager approaches another planetary system. As Carl Sagan had noted, “The spacecraft will be encountered and the record played only if there are advanced spacefaring civilizations in interstellar space. But the launching of this bottle into the cosmic ocean says something very hopeful about life on this planet.”
Why is it difficult to determine how many people speak a language?
Estimates of how many people speak a given language can vary considerably. Some surveys include only first language (native) speakers, others include both first and second language speakers (i.e., those who use the language in daily life but are not native speakers of it). Thus, Ethnologue gives the following statistics for English world-wide: first language speakers 341 million, first and second language speakers 508 million.
Writing Systems
How many languages are written?
About one-third of the world languages have a writing system.
Where did writing evolve?
Writing may have evolved independently at different times in different parts of the world, although some languages also borrowed their orthography from other languages. For instance, Japanese borrowed the characters (Kanji) from Chinese.
What impact does writing have on language?
Writing systems usually change more slowly than the spoken language. The odd spelling of many English words, for instance, reflects earlier pronunciations.
Writing can act as a unifying force. The numerous mutually unintelligible dialects of Chinese are unified by one writing system. Thus, one can often see two people speaking and drawing Chinese characters in the air at the same time. This is the only way they may be able to communicate with each other.

Different types of writing systems
There are four basic types of writing systems, as you will see below.
Alphabet-based
In alphabetic systems, there is usually some type of correspondence between graphic symbols and sounds. Languages vary in their symbol-to-sound regularity. At one extreme is Spanish which has a very regular system. At the other extreme, there are languages such as English and French that exhibit a great degree of irregularity. Alphabet-based systems are used by languages all over the world.
Here are a few samples of some of the world’s orthographies.
Consonant-based alphabets represent consonants only, or consonants plus some vowels. Full vowel indication can be added by means of diacritics, but this is not common. Most consonant-based alphabets are written from right to left. Arabic, Hebrew, and Farsi (Persian) use consonant-based alphabets. Below are samples of consonant-based orthographies. Among other languages that use Arabic script are Kurdish, Pashto, Persian/Farsi, and Urdu.
In a syllable-based writing, each symbol represents a syllable, usually a consonant-vowel pair. Syllable-based systems are common for the languages of India, Indonesia, and the Philippines.
In a logographic (also called pictographic) system, the symbols represent words or parts of words. The best known examples are Chinese characters. To read and write modern Chinese, one needs to know around 2,000 characters. Characters are traditionally written vertically from top to bottom and right to left. Chinese characters with some modifications are also used by Japanese, Korean, and Vietnamese.
Some languages use a combination of writing systems. For instance, Japanese uses a combination of two syllabaries (Katakan and Hiragana) and characters (Kanji). Korean also uses a combination of the native Korean syllable-based alphabet Hangul and borrowed Chinese characters, although the latter are not used very often.
There are writing systems that have proven to be difficult to decipher or that have yet to be deciphered. For a more complete list, go to Omniglot guide to writing systems.
