Null Models For Cultural And Social Evolution
Analogies between biological and cultural evolution date back to Darwin, yet the analogies have remained loose. Neutral evolution, known to be important in biology, has been proposed as a null model for cultural change, but has not developed into tests for selection on cultural features. Using …

Genomic studies of social evolution in bees
The eusocial insects (ants, termites, and some bees and wasps) are paragons of social complexity, with their highly organized societies comprised of primarily sterile workers, headed by one or a few reproductives. Despite a rich body of theoretical, empirical, and natural history research on social …

Social Evolution in Action: Causes and Consequences
Across the animal kingdom, social behaviour has been shown to be both a driver of and a response to selection. The question of how social interactions within the family contribute to evolutionary change has received much attention from behavioural ecologists and evolutionary biologists alike, with …

Models and Methods in Cultural and Social Evolution
… ancestors (one or two) as is typical of genetic evolution. We first show that, given a sample of individuals, a cultural common ancestor does not necessarily exist. We then introduce a related concept: the most recent unique ancestor (MRUA), i.e., the most recent single individual who is the …

Social evolution : opinions and behaviors in face-to-face networks
… ideas and opinions, and their diffusion within social networks, are important questions in education, business, and government. However until recently there has been no method to automatically capture fine-grained face-to-face interactions between people, to better model the diffusion process. …

Accounting for intraspecific variation transforms our understanding of artiodactyl social evolution
A major goal in the study of mammalian social systems has been to explain evolutionary transitions in social traits. Recent comparative analyses have used phylogenetic reconstructions to determine the evolution of social traits but have omitted intraspecific variation in social organization (IVSO) …

Changes in Islamic Hermeneutics and Social Evolution: A Comparative Study of Turkey and Algeria
In comparing the evolution of the current struggle between religious challengers and the ruling class in Algeria and Turkey, this paper examines why and how Algerians became involved in a civil war which has continued almost six years, and why Turkey was not like Algeria. In order to carry out this …

The evolution of social traits and biodiversity in the ants.
Cooperation has shaped the evolution of life on Earth. The ants are the most numerically diverse of the eusocial Hymenoptera, and display wide variation in social complexity. This positions the ants as an ideal taxon in which to study social evolution in a comparative framework. Social evolution …

Mechanisms involved in eusocial evolution in bees
A major challenge in evolutionary biology is to understand the origin and maintenance of complex animal societies. Identifying the mechanisms involved in transitions from solitary to group living can shed light on the evolutionary processes through which sociality arises. Bees are a valuable group …

Inter-individual variation within social groups: how metabolic rate shapes the pace of life
… rate might play in shaping division of labor and social evolution. Building on this work, we leveraged the well-characterized differences in MR associated with 'F' ('fast') and 'S' ('slow') malate dehydrogenase (MDH) alleles to breed homozygous genotypes of bees expressing high (FF) and low (SS) …

(Re)-programming typologies of public infrastructure to serve as a tool for cultural evolution: a re-imagination of the Cape Town Station
… Town Station as an opportunity to support the social evolution that is on our doorstep. For this I chose to explore the balances in the concepts of culture, society and identity; and consequently the ideas of typology and programming within the infrastructure of a major railway station/public …

Computer simulations of kin selection
… kin selection is central to the understanding of social evolution. Recent theoretical work suggests a limitation on the action of kin selection in structured populations. The first such limit involves a specialized population structure, termed "budding viscosity," common to social insects, in …

FROM CAMPING TO PERMANENCE: A HISTORY OF MONTANA MOBILE AND MANUFACTURED HOMES
… housing has enjoyed a dynamic historic and social evolution, as revealed by federal, state, and local documents, newspaper reports, periodicals, and interviews. Yet, manufactured housing struggles to escape its mobile origins and the negative stereotypes acquired during its rich history. In …

Charro Days: History, Culture, and Identity on the U.S.-Mexico Border
… my thesis, I explain Brownsville’s history and social makeup following the Mexican American War. I analyze the celebration and its social evolution decade by decade. I explore the ways in which Charro Days uses symbols of Mexicaness and Americaness to highlight the border’s unique position which …

Colony Life History in the Bumble Bee Bombus terrestris: Interactions, Timing and Control.
The evolutionary success of organisms is dependent on adaptive life histories, but the mechanistic control of life history traits is not often studied from an evolutionary perspective. One fascinating area with the potential to advance the understanding of life history regulation in an evolutionary …

On the Periphery of a Great "Empire": Secondary Formation of States and Their Material Basis in the Shandong Peninsula during the Late Bronze Age, ca. 1000-500 B.C.E
… one hand, this dissertation examines the dynamic social and cultural process in the eastern periphery in relation to the expansion and colonization of the Western Zhou state; on the other hand, it emphasizes the agency of the periphery during the formation of secondary states by examining how the …

Molecular analyses of endocrine and nutritional factors that affect division of labor and health in honey bees (Apis mellifera)

Evolutionary Genetics of Dictyostelids: Cryptic Species, Sociality and Sex
… discoideum serves as an ideal system to study social evolution because of the social stage of its lifecycle, where individuals aggregate to build a multicellular structure. However, much of its basic biology remains unknown and this limits its utility. I used three separate projects to fill …
