17. Natural Evolution Hypothesis Humans evolved a Language Acquisition Device . The simple vocalizations and gestures inherited from our primitive ancestors quickly gave way to a creative system of language – perhaps in a single generation or two due to a genetic mutation that produced advantageous results. One theory suggests this perhaps gave Homo sapiens an advantage over Homo neatherthalis, whose vocalizations were limited by a less developed vocal tract. Studies of Neanderthal skulls indicate that they were only able to produce fricative sounds, like /f/ and /v/. “Homo loquens” – the speaking human!
18. Invention Hypotheses “Ding-Dong” – humans named objects, actions and phenomena after a recognizable sound associated with it. The first human words were a type of ICON, a sign whose form is an exact image of its meaning: Boom = explosion (English) Tun-tun= heart (Chinook Indian) Ai-ai= knife (Basque, literally “ouch-ouch”)
19. Invention Hypotheses “bow-wow” – human vocabulary developed from animal noises, e.g., Moo, hiss, quack, meow, etc. Onomatopoeia: lit. “name-sound” the imitation of a sound in naming. Drawbacks: Limited part of vocabulary. Different from language to language: Russian ba-bakh = bang; bukh= thud
20. Invention Hypotheses “pooh-pooh” Hypothesis: humans’ first words were derived from spontaneous expressions of dislike, hunger, pain, or pleasure. Ha-ha-ha, wah-wah Problems: Very small part of any language. Differ from language to language: English ouch; Russian oi; Cherokee eee, Basqueai Made with intake of breath, which is the opposite of normal talking.
21. Invention Hypotheses Renditions of animal sounds differ considerably from language to language, even though the animal makes essentially the same sound: Dog: bow-wow; Chinese wu-wu; Jap. wan-wan; Russian gaf-gafor tyaff-tyaff Cat: meow; Russian myaoo; Chinese mao; Japanese nya-nya Rooster: cocka-doodle-do; Japanese kokekoko; Greek kikuriku, kikikiriki PROBLEM: Where do names for natural noiseless concepts come from: rock, sun, sky, love????
22. Invention Hypotheses “ta-ta” Hypothesis. Charles Darwin theorized that speech may have developed as a sort of mouth pantomime – the organs of speech were used to imitate the gestures of the hand. The first words were lip icons of hand gestures. Same problem as for onomatopoeia– different gestures in different cultures: crossing fingers for good luck in English versus Russian “fig” gesture; nodding “no” in Greek versus “yes” in English Even Darwin himself thought this was a little implausible.
23. Necessity Hypotheses “Necessity is the mother of invention” Warning Hypothesis. Language evolved from the warning signals used by animals. Perhaps language started with a warning sound to others, that signified “HELP!” or “RUN!” to alert other members to the approach of a lumbering hairy mammoth or hungry saber-tooth tiger. Other first words could have been hunting instructions.
24. Necessity Hypotheses “yo-he-ho” Hypothesis: Language developed on the basis of human cooperation. The earliest language was chanting to stimulate collective effort, like moving a great stone to block off a cave entrance from roving carnivores, or repeatinga war phrase over and over to inflame the fighting spirit. Poetry and song came to us this way – and we still have some “yo-he-ho” ones: the Volga Boat Song, Military drill chanting, the Seven Dwarves working song!
25. Necessity Hypotheses The “Lying” Hypothesis: Sturtevant argued that since all our real intentions or emotions get involuntarily expressed by gesture, look, or sound, voluntary communication must have been invented in order to lie or deceive. He believed that the need to deceive and lie – to use language in contrast to reality for selfish ends – was the social prompting that got language started. Seems pretty far-fetched.
27. Other Sources of Language More on the divine source: Psammetichus and the babies raised by goats. Ba-ba? King James of Scotland and the Hebrew-speaking babies. But empirical evidence from children raised without exposure to language shows that these children grow up with no language at all. Exposure to language before the age of 7 is critical to language development. This is called The Critical Period for language acquisition
28. Other Sources of Language Physical Adaptation. Other primates, such as gorillas, do not have the same physical characteristics which make speech possible. upright teeth in humans (fricative sounds) Intricate lip muscles on humans Smaller, thicker more muscular tongue Humans can close off the nose to create more air pressure for sound in the mouth cavity.
29. Other Sources of Language The human larynx, or “voice box,” which contains the vocal cords, is in a lower position in humans than in primates, creating a longer cavity called the pharynx. The pharynx is like a big echo chamber above the vocal cords for volume and clarity of sound. Unfortunate outcome: we can now choke on food. Monkeys can both breathe and drink or eat at the same time – we can’t. So can babies until their larynx drops as they mature.
30. Other Sources of Language The tool-making source: As early humans’ hands became occupied with tool use, they were less able to use hand gestures, so speech became a necessity Preferential right-handedness Lateralized brain: each hemisphere has its own functions Speech and tool-making abilities are very close to one another in the left hemisphere
31. Other Sources of Language The Genetic Source: a crucial genetic mutation arose which gave humans the unique ability to produce and understand language. This means that language is Innate Hard-wired like in a computer Pre-programmed Universal in form The innateness hypothesis states that language is endemic to all humans. But only to humans? We will explore this next week.

35. Linguistic Diversity Monogenesis: mono = “one” genesis = “birth” There was a single, original language spoken by a single group of Homo sapiens as early as 50,000 years ago which gave rise to all human languages spoken on earth today. The Mother Tongue Hypothesis – this original language diverged through time and distance to form many different languages. All of today’s languages descended from this one language. Out of Africa Theory – General theory of human origin arising in Africa; language may have arisen here as well.
36. Linguistic Diversity Myths Many cultures have stories about how the first language became many languages: The Tower of Babel (Genesis, Judeo-Christian) The Toltec Pyramid of Cholula (Pre-Columbian Mexico) Basque scholars claim Basque is the first language; a Swedish scholar claims Swedish was spoken in the Garden of Eden. A German scholar from the 18th century believed German was the proto-language. See a pattern?
37. Linguistic Diversity Polygenesis: poly = “many” genesis = “birth” The Candelabra Hypothesis: The hypothesis of parallelevolutionof language in more than one place and by more than one group of Homo sapiens. Each of these languages would have diverged into many forms. The major language groups of today would be descended from these separate mother tongues.
38. Comparative and Anthropological Linguistics Comparative linguists try to trace the original mother tongue (or tongues). Scholars compare modern languages and try to reconstruct ancient ones. Anthropological linguists see language as a window into the past. Language changes much more slowly than the environment in which it is spoken, so you can learn a lot about the cultural history of the people who speak a language.
39. Discussion Questions What is the basic idea behind the bow-wow theory? Why are interjections like “ouch” considered to be an unlikely source of language origin? Where is the pharynx and how did it become an important part of human sound production? What happened at the Tower of Babel, and why is it used in explaining language origins? What is the connection between the innateness hypothesis and the idea of a Universal Grammar? Why do you think that young deaf children who become fluent in sign language would be cited as a support of the innateness hypothesis?
40. Discussion Questions What is the connection between language, tool-using, and right-handedness? Why is it difficult to believe Psammetichus that Phrygian must have been the first language? What is monogenesis and how does it explain the development of languages? What theory of language diversity would explain having different families of languages?
41. Discussion Questions Is there a connection between the Heimlich maneuver and the development of human speech? What are the arguments for and against a teleological explanation of the origins of language?
