"Unbiased models are foundational in the archaeological study of cultural transmission. Applications have as- sumed that archaeological data represent synchronic samples, despite the accretional nature of the archaeological record. I document the circumstances under which time-averaging alters the distribution of model predictions. Richness is inflated in long-duration assemblages, and evenness is "flattened" compared to unaveraged samples. Tests of neutrality, employed to differentiate biased and unbiased models, suffer serious problems with Type I error under time-averaging. Finally, the time-scale over which time-averaging alters predictions is determined by the mean trait lifetime, providing a way to evaluate the impact of these effects upon archaeological samples."

"Understanding the ways in which information achieves widespread public awareness is a research question of significant interest. We consider whether, and how, the way in which the information is phrased --- the choice of words and sentence structure --- can affect this process. To this end, we develop an analysis framework and build a corpus of movie quotes, annotated with memorability information, in which we are able to control for both the speaker and the setting of the quotes. We find significant differences between memorable and non-memorable quotes in several key dimensions. One is lexical distinctiveness: in aggregate, memorable quotes use less common word choices, but at the same time are built upon a scaffolding of common syntactic patterns; another is that memorable quotes tend to be more general in ways that make them easy to apply in new contexts. We also show how the concept of "memorable language" can be extended across domains."

"Why do some music styles gain mass popularity while others thrive in small niches? Banding Together explores this question and reveals the attributes that together explain the growth of twentieth-century American popular music. Drawing on a vast array of examples from sixty musical styles--ranging from rap and bluegrass to death metal and South Texas polka, and including several created outside the United States--Jennifer Lena uncovers the shared grammar that allows us to understand the cultural language and evolution of popular music.
"What are the common economic, organizational, ideological, and aesthetic traits among contemporary genres? Do genres follow patterns in their development? Lena discovers four dominant forms--Avant-garde, Scene-based, Industry-based, and Traditionalist--and two dominant trajectories that describe how American pop music genres develop. Outside the United States there exists a fifth form: the Government-purposed genre, which she examines in the music of China, Serbia, Nigeria, and Chile. Offering a rare analysis of how music communities operate, she looks at the shared obstacles and opportunities creative people face and reveals the ways in which people collaborate around ideas, artworks, individuals, and organizations that support their work."

"Virtually all aspects of human behavior show enormous variation both within and between cultural groups, including material culture, social organization and language. Thousands of distinct cultural groups exist: about 6,000 languages are spoken today, and it is thought that a far greater number of languages existed in the past but became extinct. Using a Darwinian approach, this book seeks to explain this rich cultural variation. There are a number of theoretical reasons to believe that cultural diversification might be tree-like, that is phylogenetic: material and non-material culture is clearly inherited by descendants, there is descent with modification, and languages appear to be hierarchically related. There are also a number of theoretical reasons to believe that cultural evolution is not tree-like: cultural inheritance is not Mendelian and can indeed be vertical, horizontal or oblique, evidence of borrowing abounds, cultures are not necessarily biological populations and can be transient and complex. Here, for the first time, this title tackles these questions of cultural evolution empirically and quantitatively, using a range of case studies from Africa, the Pacific, Europe, Asia and America. A range of powerful theoretical tools developed in evolutionary biology is used to test detailed hypotheses about historical patterns and adaptive functions in cultural evolution. Evidence is amassed from archaeological, linguist and cultural datasets, from both recent and historical or pre-historical time periods. A unifying theme is that the phylogenetic approach is a useful and powerful framework, both for describing the evolutionary history of these traits, and also for testing adaptive hypotheses about their evolution and co-evolution. Contributors include archaeologists, anthropologists, evolutionary biologists and linguists, and this book will be of great interest to all those involved in these areas."

"The evolutionary history of species is traditionally represented using a rooted phylogenetic tree. However, when reticulate events such as hybridization, horizontal gene transfer or recombination are believed to be involved, phylogenetic networks that can accommodate non-treelike evolution have an important role to play. This book provides the first interdisciplinary overview of phylogenetic networks. Beginning with a concise introduction to both phylogenetic trees and phylogenetic networks, the fundamental concepts and results are then presented for both rooted and unrooted phylogenetic networks. Current approaches and algorithms available for computing phylogenetic networks from different types of datasets are then discussed, accompanied by examples of their application to real biological datasets. The book also summarises the algorithms used for drawing phylogenetic networks, along with the existing software for their computation and evaluation. All datasets, examples and other additional information and links are available from the book's companion website at www.phylogenetic-networks.org."

"When the “meme” was introduced in 1976, it was as a metaphor intended to illuminate an evolutionary argument. By the late-1980s, however, we see from its use in major US newspapers that this original meaning had become obscured. The meme became a virus of the mind. (In the UK, this occurred slightly later.) It is also now clear that this becoming involved complex sustained interactions between scholars, journalists, and the letter-writing public. We must therefore read the “meme” through lenses provided by its popularization. The results are in turn suggestive of the processes of meaning-construction in scholarly communication more generally."

Endorsed by Hodgson, but probably worth checking out anyway. "Covering a wide range of topics, including fads, public policy, the spread of religion, and herd behavior in markets, Alex Mesoudi shows that human culture is itself an evolutionary process that exhibits the key Darwinian mechanisms of variation, competition, and inheritance. This cross-disciplinary volume focuses on the ways cultural phenomena can be studied scientifically—from theoretical modeling to lab experiments, archaeological fieldwork to ethnographic studies—and shows how apparently disparate methods can complement one another to the mutual benefit of the various social science disciplines. Along the way, the book reveals how new insights arise from looking at culture from an evolutionary angle. Cultural Evolution provides a thought-provoking argument that Darwinian evolutionary theory can both unify different branches of inquiry and enhance understanding of human behavior."

"this book is about political culture. It examines developments in the social sciences and integrates them into a theoretical explanation of historical changes in political values. The starting point is the premise that political culture is rooted in the interaction between individual thinking and social norms. Through discourse, individual conceptions of social life are transformed and, interactively, social norms and cultural orientations as well. The first two parts of the book explore these issues theoretically. The second two examine them empirically by showing the ways that political cultures have changed over time. In the modern period the differences in the political cultures of capitalist and communist systems are contrasted; although both coneptualize social life in terms of property accumulation, they utilize different cultural orientations to reduce institutional transaction costs. The way the tensions between these two systems can be resolved is also explored."

New-ish BBS article claiming there isn't any universal grammar, merely several stable strategies in a sort of evolutionary game.

"For acquired behaviour to count as cultural, two conditions must be met: it must propagate in a social group, and it must remain stable across generations in the process of propagation. It is commonly assumed that imitation is the mechanism that explains both the spread of animal culture and its stability. We review the literature on transmission chain studies in chimpanzees (Pan troglodytes) and other animals, and we use a formal model to argue that imitation, which may well play a major role in the propagation of animal culture, cannot be considered faithful enough to explain its stability. We consider the contribution that other psychological and ecological factors might make to the stability of animal culture observed in the wild."

"Henrich and Boyd (2002) were the first to propose a formal model of the role of attraction in cultural evolution. They came to the surprising conclusion that, when both attaction and selection are at work, final outcomes are determined by selection alone. This result is based on a determistic view of cultural attraction, different from the probabilistic view introduced in Sperber (1996). We defend this probabilistic view, show how to model it, and argue that, when both attraction and selection are at work, both affect final outcomes."

"In the past decade it has become clear that symbolic expression associated with modern human behavior began in Africa, not Europe. And it occurred tens of thousands of years earlier than was once thought. Answering why is difficult. A first step was more reliable dating of when culturally and technologically advanced people lived during the Middle Stone Age in the south of Africa. Zenobia Jacobs and Richard G. Roberts accomplished that dating, which prompted them to reject climate change as a primary cause for the advancements. Instead, drawing on genetic research, they embrace population growth as a likely, key influence."

"The joint dynamics of population-level social institutions and individual preferences (or more broadly cultures) are illustrated in four case studies: the end of Communist Party rule in the German Democratic Republic, the transformation of traditional contracts governing agricultural work in the Philippines, the demise of Apartheid in South Africa, and the spread and retreat of female genital cutting in West Africa. A stochastic evolutionary game model of the underlying processes captures five interrelated aspects of real world historical dynamics: its often bottom- up and decentralized nature, the complementarity between cultural and institutional dynamics, the long term persistence of inefficient institutions, the often revolutionary nature of institutional and cultural change and the prominent role of technical change in the process of institutional and cultural innovation." --- Do I detect, comrades, in that last sentence, an echo of "in the last instance"?

"The origins of modern human behavior are marked by increased symbolic and technological complexity in the archaeological record. In western Eurasia this transition, the Upper Paleolithic, occurred about 45,000 years ago, but many of its features appear transiently in southern Africa about 45,000 years earlier. We show that demography is a major determinant in the maintenance of cultural complexity and that variation in regional subpopulation density and/or migratory activity results in spatial structuring of cultural skill accumulation. Genetic estimates of regional population size over time show that densities in early Upper Paleolithic Europe were similar to those in sub-Saharan Africa when modern behavior first appeared. Demographic factors can thus explain geographic variation in the timing of the first appearance of modern behavior without invoking increased cognitive capacity."

Don't ask me what the title means. Papers may be worth tracking down. Huge causal inference problems implicit here.

Update: thanks to Wolfgang for telling me that "Dengue Fever" is the name of a California-based Cambodian rock band.

Update 2: They're on emusic and they sound pretty good.

Looks great, but unfortunately the library doesn't subscribe. Waah. (Update: thanks to readers T. and W. for copies!)

Some interesting-looking papers on cultural evolution and what (if anything) we should mean by "innate".
