This study models language evolution, revealing regular and chaotic grammar shifts. The findings suggest a lack of a single evolutionarily stable strategy in language change.

Area of Science:

  • Evolutionary dynamics
  • Theoretical linguistics
  • Game theory

Background:

  • Language evolution is complex, involving changes in grammar proportions within populations.
  • Understanding these dynamics is crucial for comprehending linguistic adaptation and self-organization.

Purpose of the Study:

  • To present a novel model of language evolution.
  • To analyze the dynamics of grammar proportions over evolutionary time.
  • To explore implications for evolutionary game theory and self-organization.

Main Methods:

  • Developed a mathematical model simulating language evolution.
  • Analyzed the model for oscillations in grammar proportions.
  • Applied principles of evolutionary game theory.

Main Results:

  • The model exhibits both regular and chaotic oscillations in grammar proportions.
  • These dynamics indicate the absence of a clear evolutionarily stable strategy.
  • The findings highlight complex self-organization patterns.

Conclusions:

  • Language evolution may not converge to a single stable state.
  • Oscillating dynamics are a key feature of linguistic evolution.
  • The model provides insights into self-organization across adaptive scales.
