Abstract:
<br />
Many aspect of human behavior are attributed to culture, but the
<br />
dynamics of cultural evolution are poorly understood. Biologists have
<br />
often claimed that culture is largely shaped by a genetically
<br />
determined human nature. Social scientists, in contrast, claim that
<br />
culture is "free", meaning "free from genetic influences" but also
<br />
"free to take any direction". Here I show, with simple mathematical
<br />
models, that culture does not freely evolve, even in the absence of
<br />
genetic influences. The models show that culture itself generates
<br />
forces that systematically bias the direction of cultural evolution. A
<br />
short review of ideas about cultural evolution within the social and
<br />
biological sciences introduces the talk.
