KEY POINTS

• ZG_3_01 — The Sapir-Whorf hypothesis — more precisely, the principle of linguistic relativity — proposes that the structure of a language influences or determines the habitual thought patterns, perception,…
• ZG_3_02 — FOXP2 (Forkhead Box Protein P2) is the first gene directly linked to human speech and language ability, located on chromosome 7q31 and encoding a transcription factor that regulates hundreds of…
• ZG_3_03 — Phonetics is the scientific study of speech sounds — how they are produced by the human vocal tract (articulatory phonetics), how they propagate as acoustic signals (**acoustic…
• ZG_3_04 — Gesture and body language constitute a fundamental dimension of human communication that operates alongside, independently of, and sometimes in contradiction to spoken language.
• ZG_3_05 — The relationship between language and thought — whether the language we speak shapes, constrains, or determines how we perceive, categorize, and reason about the world — is one of the oldest and…
• ZG_3_06 — Linguistic typology is the systematic study of structural similarities and differences across the world's languages — asking what properties are universal (shared by all or nearly all…
• ZG_3_07 — Animal communication systems — the diverse repertoires of signals (vocal, visual, chemical, tactile, electrical) by which non-human species transmit information — have been the subject of…
• ZG_3_08 — Morphology — the branch of linguistics concerned with the internal structure of words — investigates how morphemes (the smallest meaningful units of language) combine to form words.
• ZG_3_09 — Syntax — the branch of linguistics that studies the structure of sentences — investigates the rules and principles governing how words combine into phrases, clauses, and sentences.
• ZG_3_10 — Semantics — the branch of linguistics concerned with meaning — investigates how words, phrases, and sentences encode and convey meaning, how meanings combine compositionally, and how…
• ZG_3_11 — Phonology — the branch of linguistics concerned with the systematic organization of speech sounds in natural languages — studies not the physical sounds themselves (that is phonetics) but the…
• ZG_3_12 — Metaphor theory — the study of how figurative language works and what it reveals about human thought — underwent a revolutionary transformation in the late 20th century with the publication of…
• ZG_3_13 — The human vocal tract is capable of producing an extraordinary range of speech sounds — far more than any single language uses.
• ZG_3_14 — Every competent language user commands a range of styles or registers — varieties of language associated with particular situations, purposes, and audiences.
• ZG_3_15 — The philosophy of linguistics investigates the foundational questions that underlie the scientific study of language: What is language?

DOCUMENT INDEX

WHAT TO EXPECT

Documents in this subfolder follow the project's 4-tier evidence system:

• Tier 1 (Verified): Peer-reviewed, archaeological record, primary texts
• Tier 2 (Credible): Academic, debated but supported by evidence
• Tier 3 (Speculative): Possible but unverified
• Tier 4 (Dubious): No credible source or contradicted by evidence

Tier distribution in this subfolder: 1: 14 docs, 1–2: 1 docs

Each document includes a Quick Summary, tiered claims with specific evidence,

counter-arguments, bibliography, and cross-references to related documents across the corpus.
