Human culture grows exponentially due to creativity, not just transmission. Increased creativity, influenced by existing culture, drives cultural accumulation and may have preceded cultural transmission

Area of Science:

  • Evolutionary biology
  • Cultural evolution
  • Cognitive science

Background:

  • Culture has historically increased exponentially in quantity.
  • The origins of culture and its exponential growth are not fully understood.
  • The role of creativity versus cultural transmission in cultural evolution is debated.

Purpose of the Study:

  • To model the interplay between human creativity and cultural transmission.
  • To investigate the conditions necessary for exponential cultural growth.
  • To determine the role of creativity in the origin of culture.

Main Methods:

  • Mathematical modeling of cultural evolution.
  • Analysis of factors influencing creativity and cultural transmission.
  • Simulation of cultural accumulation dynamics.

Main Results:

  • Creativity is essential for exponential cultural growth; transmission alone is insufficient.
  • Exponential cultural increase requires creativity to be positively influenced by the existing culture.
  • Increased individual creativity may have been the initial driver for the evolution of cultural transmission.

Conclusions:

  • Creativity is a primary engine of cultural accumulation throughout history.
  • A feedback loop where culture enhances creativity is necessary for exponential cultural growth.
  • Enhanced individual creativity likely preceded and facilitated the evolution of cultural transmission, overcoming a key bottleneck in culture's origin.
