To evaluate the hypothesis that symbolic protolanguage was culturally invented by early modern humans prior to the biological evolution of recursive syntax.
Synthesized theoretical models spanning evolutionary biology, cognitive linguistics, and information theory.
Formulated three testable hypothesis clusters addressing language invention, information-theoretic encoding, and downstream biological consequences.
Proposed that early humans culturally invented a Free-Form Protolanguage (FFP) lacking grammar, which created selective pressure for the subsequent biological evolution of recursive syntax.
Conceptualized vocabulary and grammar as compression algorithms that expand effective data transmission well beyond baseline acoustic speech rates (~39 bits/s).
Hypothesized that language advantages drove rapid global dispersal and extended post-reproductive lifespans via cultural transmission and elder survivorship.
