Origin of Language Lecture 1

1. Introduction and Core Concepts

Language is a rule-governed, symbolic, and creative system of signs used for communication and thought. It allows speakers to construct completely new sentences (productivity) and express abstract ideas.

  • Distinctions in Linguistics:

    • Speech: The vocal-auditory channel of communication. Language includes speech, but signed languages prove that speech is not mandatory for full linguistic expression.
    • Writing: A visual representation of speech/language developed much later in human history.
    • Language: A symbolic, rule-governed system connecting meaning, grammar, and social interaction.

  • Challenges in Studying Language Origins:

    • Lack of direct records: Early spoken or signed forms left no audio, visual, or fossilized records.
    • Fossil limitations: Bone structures do not reveal specific grammar, meaning, or soft-tissue vocal nuances.
    • Rapid change: Ancient languages cannot be reconstructed back to an absolute "first language."
    • Ethical boundaries: Deprivation experiments on infants are ethically unacceptable.

  • Types of Evidence Used:

    • Anatomy & Brain: Structural adaptations in the vocal tract and neural networks for sequencing.
    • Genetics & Acquisition: Inherited biological capacities and child language development stages.
    • Sign Languages & Archaeology: Spontaneous grammar emergence (e.g., Nicaraguan Sign Language) and symbolic artifacts.
2. Traditional and Classical Theories
2.1 Divine Source Theory
  • Core Concept: Claims language was bestowed upon humans by a divine power or sacred origin.
  • Cultural Perspectives:
    • Biblical Tradition: Adam names living creatures, establishing authority and human knowledge.
    • Qur'anic Tradition: Adam is taught the names of objects by God, linking language to divine knowledge.
    • Hindu Tradition: Sarasvati is revered as the goddess of speech, learning, and wisdom.
  • Evaluation: Explains cultural and sacred values attributed to speech, but cannot be scientifically tested or used to explain the historical development of grammar.
2.2 Historical Isolation Experiments
  • Historical accounts (e.g., King Psammetichus/Psamtik, King James IV of Scotland) isolated children to identify an "original" innate language.
  • Scientific Critique: Lack of normal linguistic and social input prevents normal cognitive and language development; ethically unacceptable today.
3. Natural Sound Theories
3.1 Bow-Wow Theory (Imitation)
  • Concept: Early words originated as imitations of natural environmental sounds (onomatopoeia).
  • Examples: Words like cuckoo, buzz, splash, and hiss.
  • Limitation: Most words in human languages are arbitrary, not imitative; different languages represent identical sounds differently (e.g., English bow-wow vs. Japanese wan-wan).
3.2 Pooh-Pooh Theory (Emotional Cries)
  • Concept: Language arose from instinctive vocal expressions of emotion (pain, surprise, anger).
  • Examples: Interjections such as ouch, ah, or wow.
  • Limitation: Emotional interjections are involuntary and often produced while inhaling, whereas language requires deliberate, structural, and grammatical articulation.
3.3 Ding-Dong Theory (Sound Symbolism)
  • Concept: Suggests an inherent resonance or natural connection between specific sounds and their meanings.
  • Examples: High/front vowels (teeny, slim) vs. low/back vowels (large, boom).
  • Limitation: Cannot account for the vast majority of arbitrary vocabulary (e.g., tree, justice).
3.4 Yo-He-Ho Theory (Rhythm and Cooperation)
  • Concept: Language evolved from rhythmic chants and vocalizations made during collective physical effort.
  • Examples: Heave-ho calls, work songs, and rowing chants.
  • Strength: Highlights social interaction, group coordination, and shared attention as key drivers in communication.
  • Limitation: Explains rhythmic coordination but fails to explain syntax, vocabulary growth, or abstract thought.
4. Gestural and Physical Adaptation Theories
4.1 Oral-Gesture and Gesture-First Theories
  • Concept: Claims manual pointing, pantomime, and facial expressions preceded or co-evolved alongside spoken language.
  • Key Evidence:
    • Nicaraguan Sign Language (NSL): Demonstrates that deaf children interacting together can spontaneously create a complex, structured spatial grammar without pre-existing spoken models.
    • Multimodality: Modern speech remains intrinsically linked with manual gestures and facial expressions.
  • Limitation: Manual gesture requires line-of-sight visibility (unlike speech in the dark or while working with hands). Modern consensus favors co-evolution of speech and gesture.
4.2 Physical Adaptations for Speech
  • Anatomic Features:
    • Teeth & Lips: Upright, even teeth assist with labiodental sounds; flexible lips enable bilabial sounds.
    • Tongue: Smaller, highly muscular, and flexible tongue allows precise articulation of varied vowels and consonants.
    • Larynx & Pharynx: Lowered larynx provides a larger resonance cavity (pharynx), enabling distinct vowel sounds.
  • Tool-Making Connection: Constructing stone tools requires sequential planning, fine motor control, and teaching—cognitive processes shared with syntactic language structure.
  • Limitation: Anatomical capacity provides the physical mechanism for producing sound, but does not explain how sounds acquired symbolic meaning or complex grammar.
5. Genetic, Innate, and Contemporary Perspectives
5.1 Innateness and Universal Grammar
  • Chomsky's Perspective: Humans possess an innate biological preparedness for language (Language Acquisition Device / Universal Grammar).
  • Evidence from Acquisition:
    • Children acquire language rapidly without explicit formal instruction.
    • Children produce creative errors (e.g., goed, mouses), proving they apply internalized structural rules rather than merely repeating heard speech.
5.2 Genetic Factors (FOXP2)
  • Mutations in the FOXP2 gene lead to specific speech and language disorders.
  • Clarification: FOXP2 is not a single "language gene," but rather one component of a complex genetic and neural network supporting speech motor control and cognitive processing.
5.3 Modern Multi-Factor Synthesis
  • Current research views language origin not as a single event or source, but as an evolutionary interaction across multiple domains:
    1. Biological: Vocal tract anatomy, FOXP2 gene, specialized neural networks.
    2. Cognitive: Categorization, sequential planning, memory, displacement.
    3. Social & Cultural: Joint attention, cooperative intent, teaching, and cultural transmission.
