Diversification and Extinction Processes in Cultural Evolution
The unprecedented scale of cultural extinctions, greatly exceeding the rate of creation of new cultures, is widely appreciated in evolutionary human sciences; yet few studies examined the phenomena with empirical data. Many aspects of culture leave no trace in history, making it difficult to measure...

The unprecedented scale of cultural extinctions, greatly exceeding the rate of creation of new cultures, is widely appreciated in evolutionary human sciences; yet few studies examined the phenomena with empirical data. Many aspects of culture leave no trace in history, making it difficult to measure and assess how cultural diversity changed over time. Cultural traits have functional significance and hence a behavioural ecological approach can help us understand their prevalence and loss. This thesis aims to examine cultural diversification and extinction processes empirically, using phylogenetic comparative methods at the macro-evolutionary level and applying the behavioural ecology framework at the micro-evolutionary level. Chapter 2 reviews phylogenetic comparative methods, their applications, recent developments, and potential pitfalls. Chapter 3 and 4 reconstruct the macro-evolution of Sino-Tibetan cultures and their kinship systems, with discussions on evolutionary processes of language dispersal and diversification of gender-biased dispersal norms. Chapter 5 presents the macro-evolutionary study of historical Islamic sects, using cultural phylogenetics to examine the evolutionary relationship between afterlife beliefs and intergroup conflicts and whether cultural traits may accelerate or delay the extinction of religious groups.
