Negative feedback-loop
Neanderthal thesis:
Changing demography, too many adaptations, leads to extinction
3. The apprentice
learning model
- The theory of Runia on discontinuities fits perfectly in the framework of social learning of Sterelny.
- Cultural evolution and Cultural learning are both the same as respectively social evolution and social learning.
At the core copes with social learning:
"A model of human social learning" (p.138)
1. Not explicit or formalized (ethnographic data)
2. The incremental construction of apprentice learning
3. Support high fidelity knowledge flow
4. Model illuminates the archeological record
Interaction source-sink = adaptation both ways

Evolved apprentice
A lot of international praise: prizes and reviews
- Human adaption to environment
- Cultural (social) evolution not to be described in a key innovation model
- Feedback loops & ratchet principle
- Incremental change vs. catastrophes
Loop 1 Loop 2
1. Plastic phenotype
Adaptation to a changing environment enables evolution
"Environmental change thus often brings with it a changed population and that in turn also changes the selective environment" (p.41)
Runia: Human genotype hardly evolved in the last 10.000nds of years, due to there ability to influence their environment
The Evolved Apprentice -
How evolution made humans unique
Are there any questions
(for Dr. Runia)?
