“…We used a Bayesian implementation of the MK test (11) to estimate the strength and direction of selection on 12,303 genes since divergence between A. mellifera and A. cerana ∼5-25 Mya (24,25). The MK test requires polymorphism data from at least one species (i.e., A. mellifera) and divergence data from at least one outgroup sequence (i.e., A. cerana) (10,26,27), and the Bayesian implementation of the MK test allows for the estimation of the population size-scaled selection coefficient γ on nonsynonymous mutations (11).…”

“…Positive selection facilitating local adaptation creates loci with outlier levels of genetic differentiation (F ST ) relative to the rest of the genome (12,13). We used outlier levels of F ST to identify loci that have likely experienced geographically restricted positive selection since divergence of A. mellifera's four evolutionary lineages ∼1 Mya to 11,000 y ago (24,25). We used two approaches to detect genomic windows (≥5 kb) (Dataset S2) and SNPs with outlier levels of F ST (Fig.…”

Most theories used to explain the evolution of eusociality rest upon two key assumptions: mutations affecting the phenotype of sterile workers evolve by positive selection if the resulting traits benefit fertile kin, and that worker traits provide the primary mechanism allowing social insects to adapt to their environment. Despite the common view that positive selection drives phenotypic evolution of workers, we know very little about the prevalence of positive selection acting on the genomes of eusocial insects. We mapped the footprints of positive selection in Apis mellifera through analysis of 40 individual genomes, allowing us to identify thousands of genes and regulatory sequences with signatures of adaptive evolution over multiple timescales. We found Apoidea-and Apis-specific genes to be enriched for signatures of positive selection, indicating that novel genes play a disproportionately large role in adaptive evolution of eusocial insects. Worker-biased proteins have higher signatures of adaptive evolution relative to queen-biased proteins, supporting the view that worker traits are key to adaptation. We also found genes regulating worker division of labor to be enriched for signs of positive selection. Finally, genes associated with worker behavior based on analysis of brain gene expression were highly enriched for adaptive protein and cis-regulatory evolution. Our study highlights the significant contribution of worker phenotypes to adaptive evolution in social insects, and provides a wealth of knowledge on the loci that influence fitness in honey bees.natural selection | kin selection | social evolution | taxonomically restricted genes E usocial behavior evolved multiple times in insects and is characterized in part by extreme asymmetries in the reproductive potential of individuals (1). This asymmetry is most pronounced in advanced eusocial insects, with their fertile queen and sterile worker castes. Darwin first recognized that natural selection cannot directly optimize worker phenotypes because workers are usually sterile (2). Hamilton (3, 4) developed kinselection theory to describe the conditions that allow natural selection to indirectly optimize worker phenotypes if such phenotypes benefit their fertile kin. It is commonly believed that worker traits, such as sib-care, foraging, and colony defense, play important roles in allowing colonies to adapt to their environment (5-7). However, despite the central role of kin-selection and inclusive fitness theory in the field of Sociobiology (8, 9), we lack knowledge on the pattern and prevalence of positive selection acting on the genomes of eusocial insects.Population genomic studies provide unprecedented opportunities to detect signatures of selection on DNA sequences over different timescales (10). There are several tests of selection that can be applied to genome-wide datasets. The McDonald-Kreitman (MK) test is arguably the best method for detecting selection on protein coding sequences because of its robustness to changes in a species' demography,...

“…The Western honeybee originated in Africa and subsequently expanded into Eurasia in two or more independent ancient expansions (10,15). The divergence among the subspecies is estimated at 0.7-1.3 million years (11,16). Relative to this period of adaptation of each subspecies to its local climate and habitat, the ∼3,000 years elapsed from the estimated destruction of the Tel Reh : ov apiary is very short.…”

Although texts and wall paintings suggest that bees were kept in the Ancient Near East for the production of precious wax and honey, archaeological evidence for beekeeping has never been found. The Biblical term "honey" commonly was interpreted as the sweet product of fruits, such as dates and figs. The recent discovery of unfired clay cylinders similar to traditional hives still used in the Near East at the site of Tel Reh : ov in the Jordan valley in northern Israel suggests that a large-scale apiary was located inside the town, dating to the 10th-early 9th centuries B.C.E. This paper reports the discovery of remains of honeybee workers, drones, pupae, and larvae inside these hives. The exceptional preservation of these remains provides unequivocal identification of the clay cylinders as the most ancient beehives yet found. Morphometric analyses indicate that these bees differ from the local subspecies Apis mellifera syriaca and from all subspecies other than A. m. anatoliaca, which presently resides in parts of Turkey. This finding suggests either that the Western honeybee subspecies distribution has undergone rapid change during the last 3,000 years or that the ancient inhabitants of Tel Reh : ov imported bees superior to the local bees in terms of their milder temper and improved honey yield.Apis mellifera | domestication | biogeography | climate change | Iron Age IIA

“…Sweat bees were added as basal to the long-tongued bees (Alexander and Michener 1995). For honeybees, leafcutter ants, and bumblebees, the molecular phylogenies of Arias and Sheppard (2005), Villesen et al (2002), and Kawakita et al (2004) were used. Relationships among the Polistinae wasps followed the combined morphological and molecular phylogeny of Arévalo et al (2004).…”

In many bees, wasps, and ants, workers police each other in order to prevent individual workers from selfishly producing their own male offspring. Although several factors can selectively favor worker policing, genetic relatedness is considered to be of special importance. In particular, kin selection theory predicts that worker policing should be more common in species where workers are more related to the queen's sons than to other workers' sons. Here we provide strong novel support for this theory based on a comparative analysis of policing and male parentage in 109 species of ants, bees, and wasps. First, an analysis of behavioral data confirms that worker policing occurs more frequently in species where workers are more related to the queen's sons than to other workers' sons. Second, an analysis of male parentage shows that a significantly higher percentage of the males are workers' sons in species where the workers are more related to other workers' sons. Both conclusions also hold if data are analyzed using phylogenetically independent contrasts. Although our analysis provides strong overall support for the theory that relatedness affects kin conflict over male parentage, there is also significant residual variation. Several factors that may explain this variation are discussed.Keywords: worker policing, queen policing, worker reproduction, social Hymenoptera, inclusive fitness, kin selection.A major challenge in evolutionary biology is to explain how social groups can reduce or prevent costly conflicts
