The genetic origin of advanced social organization has long been one of the outstanding problems of evolutionary biology. Here we present an analysis of the major steps in ant evolution, based for the first time, to our knowledge, on combined recent advances in paleontology, phylogeny, and the study of contemporary life histories. We provide evidence of the causal forces of natural selection shaping several key phenomena: (i) the relative lateness and rarity in geological time of the emergence of eusociality in ants and other animal phylads; (ii) the prevalence of monogamy at the time of evolutionary origin; and (iii) the female-biased sex allocation observed in many ant species. We argue that a clear understanding of the evolution of social insects can emerge if, in addition to relatedness-based arguments, we take into account key factors of natural history and study how natural selection acts on alleles that modify social behavior.sociobiology | claustrality | adaptive radiation | inadequacy of inclusive fitness

“…The Permian gigantopterids, largely found as compression fossils in China and the central United States, are well-known for their angiosperm-like vegetative organs, including large, entire-margined leaves and putative vessel elements (Beck and Labandeira 1998, Glasspool et al 2004a, Glasspool et al 2004b, Li and Taylor 1998, Li et al 1996, Mamay et al 1988. Although permineralized specimens are rare, and reproductive organs have never been found-preventing any taxonomic link with other seed plant groups-gigantopterid vegetative features suggest that they may resemble medullosans and angiosperms in functional space, rather than conifers.…”

“…4). There is evidence for host specificity, as already established for the Cisuralian and Lopingian localities of north-central Texas and South Africa (Beck and Labandeira, 1998;Prevec et al, 2009;Schachat et al, 2014. At Bletterbach, taeniopterid-like leaves exhibit a sixfold higher damage frequency (9%) than their frequency in the flora would indicate (1.5%).…”

Keywords:Tetrapoda flora phytoprovinces plant-insect interactions climate endemism latitudinal diversity gradient A B S T R A C TThe late Palaeozoic is a pivotal period for the evolution of terrestrial ecosystems. Generalised warming and aridification trends resulted in profound floral and faunal turnover as well as increased levels of endemism. The patchiness of well-preserved, late Permian terrestrial ecosystems, however, complicates attempts to reconstruct a coherent, global scenario. In this paper, we provide a new reconstruction of the Bletterbach Biota (Southern Alps, NE Italy), which constitutes a unique, low-latitude record of Lopingian life on land. We also integrate floral, faunal (from skeletal and footprint studies), and plant-insect interaction data, as well as global climatic interpretations, to compare the composition of the 14 best-known late Permian ecosystems. The results of this ecosystem-scale analysis provide evidence for a strong correlation between the distribution of the principal clades of tetrapod herbivores (dicynodonts, pareiasaurs, captorhinids), phytoprovinces and climatic latitudinal zonation. We show that terrestrial ecosystems were structured and provincialised at high taxonomic levels by climate regions, and that latitudinal distribution is a key predictor of ecosystem compositional affinity. A latitudinal diversity gradient characterised by decreasing richness towards higher latitudes is apparent: mid-to lowlatitude ecosystems had the greatest amount of high-level taxonomic diversity, whereas those from high latitudes were dominated by small numbers of higher taxa. The high diversities of tropical ecosystems stem from their inclusion of a mixture of late-occurring holdovers from the early Permian, early members of clades that come to prominence in the Triassic, and contemporary taxa that are also represented in higher latitude assemblages. A variety of evidence suggests that the Permian tropics acted as both a cradle (an area with high origination rates) and museum (an area with low extinction rates) for biodiversity.
