The objective of this article is to clarify the nature of the methodological position called adaptationism in evolutionary biology (that is, a position holding natural selection to be ubiquitous and the most powerful as a mechanism of the evolution of life) and to discuss the problems that relate to it. To this end, I will first set forth the controversy having been waged on the legitimacy of adaptationism, originally initiated by Gould and Lewontin in 1978 and having been joined by mainstream neo-Darwinists ever since. Then I will put forward some framework for evaluating this controversy, namely, the idea of taking adaptationism to be a research program in Lakatos' sense. In the second section, I will review, somewhat critically, how adaptationistic thinking is exemplified in the sociobiological research program advocated by E. O. Wilson and his followers. In the third section, I will give some considerations on the possibility of the model of cultural evolution (memetics) as a complement to the one-sidedness of the genetically-biased sociobiological explanation of human culture.
