Document Summary
Topic: human language- cooperation and information exchange- part 2. Evolution of communication is like evolution of all other kinds of cooperation. Dichotomy in humans because of our lost cost of coercion, we can drive evolution of. (cid:498)liar(cid:499) broadly defined- engaged in all kind of deception kinship independent social cooperation. In ancestral condition, human social scale was much larger than in non-human animals. We expect non human animals to participate in language like behavior but to do so on a much larger scale- members of massive group that can hold massive cultural information. Enormous pressure on us to produce info and comprehend that info. We expect ancient ancestral like behavior in non human animals be dramatically expanded in us- specific prediction of social coercion theory. Elite communication is spoken about broadly- exchange info in all kinds of modalities on a vastly greater scale and can predict when that happened. Started evolving that very rapidly just exactly during brain expansion.
