Early Evolution of Bird-Type Language without Grammar: Duplication and Mutation

TL;DR

This paper uses computer simulations to explore how primitive bird-like languages could have evolved through duplication and mutation of phrases, without the need for grammatical structures.

Contribution

It introduces a novel simulation approach demonstrating early language evolution driven solely by duplication and mutation, without assuming grammatical competence.

Findings

Primitive language can evolve through duplication and mutation alone.

Grammar is not necessary for the emergence of early communication systems.

Simulation results support the plausibility of non-grammatical language evolution.

Abstract

Using a series of computer simulations we have demonstrated a scenario of the early evolution of the bird-type primitive language. We do not assume wise agents who can use a grammar and manage an evolution without a grammar. Duplication and mutation of phrases is our strategy. Such a strategy is seen in wide classes of living phenomena.
