Four experiments tested the novel hypothesis that ritualistic behavior potentiates and enhances ensuing consumption-an effect found for chocolates, lemonade, and even carrots. Experiment 1 showed that participants who engaged in ritualized behavior, compared with those who did not, evaluated chocolate as more flavorful, valuable, and deserving of behavioral savoring. Experiment 2 demonstrated that random gestures do not boost consumption as much as ritualistic gestures do. It further showed that a delay between a ritual and the opportunity to consume heightens enjoyment, which attests to the idea that ritual behavior stimulates goal-directed action (to consume). Experiment 3 found that performing a ritual oneself enhances consumption more than watching someone else perform the same ritual, suggesting that personal involvement is crucial for the benefits of rituals to emerge. Finally, Experiment 4 provided direct evidence of the underlying process: Rituals enhance the enjoyment of consumption because of the greater involvement in the experience that they prompt.

This paper gives a state of the art report of an ongoing interdisciplinary project on bioarchaeological research on cemeteries in the Upper Orkhon valley, Central Mongolia, in particular at the Maikhan Tolgoi site. The archaeological focus is on the investigation of the development, use and transformation of a ritual landscape in the course of the Bronze and Iron Age. The contribution of physical anthropology is an osteological and archaeometric analysis of the human inhumations with regard to life-style and subsistence economy. A specific topic relates to the emergence of the first mounted nomads in the region. Macro- and microscopical inspection of the skeletons excavated to date reveal that males, females and children had been buried at this exceptional cemetery, and that many of the adults died at a conspicuously advanced age. Palaeodiet was reconstructed by stable carbon and nitrogen isotopes in bone collagen, followed by an isotopic sourcing. We show that freshwater fish was consumed on a regular basis, and that the demands of protein and carbohydrate were largely covered by secondary animal products. First analysis of stable strontium and oxygen isotopes in bone apatite suggests a considerable catchment area of the burial site.

The Genetics of Mating Song Evolution Underlying Speciation: Linking Quantitative Variation to Candidate Genes for Behavioral Isolation.

Differences in mating behaviors evolve early during speciation, eventually contributing to reproductive barriers between species. Knowledge of the genetic and genomic bases of these behaviors is therefore integral to a causal understanding of speciation. Acoustic behaviors are often part of the mating ritual in animal species. The temporal rhythms of mating songs are notably species-specific in many vertebrates and arthropods and often underlie assortative mating. Despite discoveries of mutations that disrupt the temporal rhythm of these songs, we know surprisingly little about genes affecting naturally occurring variation in the temporal pattern of singing behavior. In the rapidly speciating Hawaiian cricket genus Laupala, the striking species variation in song rhythms constitutes a behavioral barrier to reproduction between species. Here, we mapped the largest-effect locus underlying interspecific variation in song rhythm between two Laupala species to a narrow genomic region, wherein we find no known candidate genes affecting song temporal rhythm in Drosophila Whole genome sequencing, gene prediction and functional annotation of this region reveal an exciting and promising candidate gene, the putative cyclic nucleotide-gated ion channel-like gene, for natural variation in mating behavior. Identification and molecular characterization of the candidate gene reveals a non-synonymous mutation in a conserved binding domain, suggesting the hypothesis that ion channels are important targets of selection of rhythmic signaling during establishment of behavioral isolation and rapid speciation.
