Studies of primate cognition have conclusively shown that humans and apes share a range of basic cognitive abilities. As a corollary, these same studies have also focussed attention on what makes humans unique, and on when and how specifically human cognitive skills evolved. There is widespread agreement that a major distinguishing feature of the human mind is its capacity for causal reasoning. This paper argues that causal cognition originated with the use made of indirect natural signs by early hominins forced (...) to adapt to variable late Miocene and early Pliocene environments; that early hominins evolved an innate tendency to search for such signs and infer their causes; that causal inference required the existence of incipient working memory; and that causal relationships were stored through being integrated into spatial maps to create increasingly complex causal models of the world.

Two recent attempts to clarify misunderstandings about the nature of cultural evolution came to very different conclusions, based on very different understandings of what evolves and how. This paper begins by examining these two ‘clarifications’ in order to reveal their key differences, and goes on to rethink how culture evolves by focussing on the role of cognitive structure, or worldview.

Several attempts have been made recently to apply Darwinian evolutionary theory to the study of culture change and social history. The essential elements in such a theory are that variations occur in population, and that a process of selective retention operates during their replication and transmission. Location of such variable units in the semantic structure of cognition provides the individual psychological basis for an evolutionary theory of history. Selection operates on both the level of cognition and on its phenotypic expression (...) in action in relation to individual preferred sources of psychological satisfaction. Social power comprises the principal selective forces within the unintended consequences of action and through the struggle of individuals and groups in pursuit of opposing interests. The implication for historiography are methodological in that evolutionary theory of history sharpens the focus of explanatory situational analysis, and interpretive in that it provides a paradigmatic metanarrative for the understanding of historical change.

In his latest contribution to the application of Darwinian evolutionary thinking to the social sciences, W. G. Runciman conceives of human behavior as resulting from three levels of selection - biological, cultural, and social. These give rise, respectively, to evoked, acquired, and imposed patterns of behavior. The biological level is hardly controversial, but to draw a distinction between separate cultural and social selective processes is more problematic. Runciman takes memes to be the variants competitively selected at the cultural level and (...) the practices constituting rule-governed roles to be the variants competitively selected at the social level - thus preserving separate spheres of research for anthropology and sociology. It is not clear, however, what drives cultural and social evolution. Nor are the three levels theoretically well integrated. The book's strength lies in the numerous examples provided of how the application of selectionist theory illuminates and enriches sociological and historical explanations and contributes to the construction of historical narrative.

Several attempts have been made recently to apply Darwinian evolutionary theory to the study of culture change and social history. The essential elements in such a theory are that variations occur in a population, and that a process of selective retention operates during their replication and transmission. Location of such variable “units” in the semantic structure of cognition provides the individual psychological basis for an evolutionary theory of history. Selection operates on both the level of cognition and on its “phenotypic” (...) expression in action in relation to individual preferred sources of psychological satisfaction. Social power comprises the principal selective forces within the sociocultural environment. Sociocultural evolution takes place both as a result of the unintended consequences of action and through the struggle of individuals and groups in pursuit of opposing interests. The implications for historiography are methodological in that evolutionary theory of history sharpens the focus of explanatory situational analysis, and interpretive in that it provides a paradigmatic metanarrative for the understanding of historical change.
