Abstract
This paper summarizes efforts to computationally mod- el two transitions in the evolution of human creativity: its origins about two million years ago, and the ̳big bang‘ of creativity about 50,000 years ago. Using a computational model of cultural evolution in which neural network based agents evolve ideas for actions through invention and imitation, we tested the hypothe- sis that human creativity began with onset of the capaci- ty for recursive recall. We compared runs in which agents were limited to single-step actions to runs in which they used recursive recall to chain simple actions into complex ones. Chaining resulted in higher diversi- ty, open-ended novelty, no ceiling on the mean fitness of actions, and greater ability to make use of learning. Using a computational model of portrait painting, we tested the hypothesis that the explosion of creativity in the Middle/Upper Paleolithic was due to onset of con- textual focus: the capacity to shift between associative and analytic thought. This resulted in faster conver- gence on portraits that resembled the sitter, employed painterly techniques, and were rated as preferable. We conclude that recursive recall and contextual focus pro- vide a computationally plausible explanation of how humans evolved the means to transform this planet.
