Charles Darwin and the evolution of human grammatical systems

Area of Science:

• Comparative psychology
• Evolutionary biology
• Linguistics

Background:

• Aristotle's association psychology influenced Darwin's theories on animal communication.
• Contiguity and similarity were key principles in early associationist models of mental events.
• Darwin proposed a continuity in serial ordering between humans and nonhuman animals.

Discussion:

• Modern computational methods allow for reevaluation of historical theories on serial ordering.
• The study examines starling birdsong syntax in light of Darwin's continuity hypothesis.
• Associationist principles of contiguity and concatenation informed early models of perception and action.

Key Insights:

• Starling birdsong serial ordering does not exhibit syntax analogous to human grammatical structures.
• Darwin's concept of 'degree' continuity in serial ordering between species is challenged.
• The study contrasts computational approaches to serial ordering with historical associationist theories.

Outlook:

• Further research can explore other animal communication systems for evidence of complex syntax.
• Investigating the mathematical underpinnings of serial ordering may refine comparative analyses.
• This work prompts a re-examination of the evolutionary origins of syntax.
