Cultural evolution differs from biological evolution, lacking a mechanism to discard acquired traits. Communal exchange offers a non-Darwinian evolutionary framework for culture, distinct from self-replicating automata, and supports societal evolution.
Area of Science:
- Evolutionary biology
- Social sciences
- Cultural evolution
Background:
- Dawkins' replicator theory misapplies selectionism in social sciences.
- Organisms accumulate change despite acquired traits being lost.
- Von Neumann's self-replicating automaton (SRA) model addresses this paradox.
Purpose of the Study:
- To propose an evolutionary framework for culture distinct from selectionism.
- To explore non-Darwinian processes in biological and cultural evolution.
- To identify cognitive features necessary for cultural evolution in societies.
Main Methods:
- Analysis of self-replicating automaton (SRA) concepts.
- Examination of cultural evolution mechanisms, contrasting with biological inheritance.
- Proposal and support of communal exchange as a cultural evolutionary framework.
- Computational modeling and conceptual network programming for cultural evolution.
Main Results:
- Cultural evolution lacks a mechanism for discarding acquired change, unlike biological evolution.
- Acquired changes in culture can rapidly overwhelm inherited changes.
- Communal exchange, a non-Darwinian process, provides a viable evolutionary framework for culture.
- The proposed framework supports cognitive features for societal cultural evolution.
Conclusions:
- A selectionist framework is insufficient for cultural evolution.
- Non-Darwinian processes like communal exchange are crucial for understanding biological and cultural evolution.
- The communal exchange framework is supported by computational models and aligns with human cooperation.
