Language evolutionLanguage evolution
Scientific objective: identify and test theories regarding origins
and evolution of language(s).
Engineering objective: build machines that can develop their own
language-like communication system

Symbol grounding problemSymbol grounding problem
How do seemingly meaningless symbols become meaningful? (Harnad 1990)
From: Pfeifer & Scheier 1999
Physical symbol system hypothesis: PSS are both sufficient and necessary condition for intelligence (Newel & Simon 1976).
The symbols of a PSS only meaningful to an external observer.
