Abstract. We investigate the following question. Do populations of
evolving agents adapt only to their recent environment or do general
adaptive features appear over time? We find statistically significant ap-
pearance of general adaptive features in a spatially distributed popula-
tion of prisoner's dilemma playing agents in a noisy environment. Mul-
tiple populations are evolved in an evolutionary algorithm structured
as a cellular automaton with states drawn from a rich set of prisoner's
dilemma strategies. Populations are sampled early and at the end of a
