“…Srokalarva berthei is a putative holometabolan larva, from the Mazon Creek and thus younger than W. maryvonneae. S. berthei has been interpreted as both an antliophoran (Labandeira, 2011) and a neuropterid , both positions within the crown group of Holometabola. S. berthei, however, remains informative about the evolutionary timing of insect metamorphosis.…”

Fossil age data and molecular sequences are increasingly combined to establish a timescale for the Tree of Life. Arthropods, as the most species-rich and morphologically disparate animal phylum, have received substantial attention, particularly with regard to questions such as the timing of habitat shifts (e.g., terrestrialisation), genome evolution (e.g., gene family duplication and functional evolution), origins of novel characters and behaviours (e.g., wings and flight, venom, silk), biogeography, rate of diversification (e.g., Cambrian explosion, insect coevolution with angiosperms, evolution of crab body plans), and the evolution of arthropod microbiomes. We present herein a series of rigorously vetted calibration fossils for arthropod evolutionary history, taking into account recently published guidelines for best practice in fossil calibration. These are restricted to Palaeozoic and Mesozoic fossils, no deeper than ordinal taxonomic level, nonetheless resulting in 79 fossil calibrations for 101 clades. This work is especially timely owing to the rapid growth of molecular sequence data and the fact that many included fossils have been described within the last five years. This contribution provides a resource for systematists and other biologists interested in deep-time questions in arthropod evolution.

“…Benton et al (2009) proposed an Artinskian age (284.4 ± 0.7 Myr, Permian) for the best minimum constraint on the divergence of Paraneoptera and Holometabola, on the sole basis of the Archescytinidae. Nevertheless Nel et al (2007a) described a Holometabola in the same Upper Carboniferous strata as those that gave the two paraneopteran Bruayaphis and an undescribed Carboniferous new genus and species of Thripida (see Nel et al, in press), demonstrating that both clades Holometabola and Paraneoptera are certainly Carboniferous age (Labandeira, 2011).…”

Two different patterns of wing venation are currently supposed to be present in each of the three orders of Paraneoptera. This is unlikely compared with the situation in other insects where only one pattern exists per order. We propose for all Paraneoptera a new and unique interpretation of wing venation pattern, assuming that the convex cubitus anterior gets fused with the common stem of median and radial veins at or very near to wing base, after separation from concave cubitus posterior, and re-emerges more distally from R + M stem. Thereafter, the vein between concave cubitus posterior and CuA is a specialized crossvein called "cua-cup," proximally concave and distally convex. We show that despite some variations, that is, cua-cup can vary from absent to hypertrophic; CuA can re-emerge together with M or not, or even completely disappear, this new interpretation explains all situations among all fossil and recent paraneopteran lineages. We propose that the characters "CuA fused in a common stem with R and M"and "presence of specialized crossvein cua-cup" are venation apomorphies that support the monophyly of the Paraneoptera. In the light of these characters, we reinterpret several Palaeozoic and early Mesozoic fossils that were ascribed to Paraneoptera, and confirm the attribution of several to this superorder as well as possible attribution of Zygopsocidae (Zygopsocus permianus Tillyard, 1935) as oldest Psocodea. We discuss the situation in extinct Hypoperlida and Miomoptera, suggesting that both orders could well be polyphyletic, with taxa related to Archaeorthoptera, Paraneoptera, or even Holometabola. The Carboniferous Protoprosbolidae is resurrected and retransferred into the Paraneoptera. The genus Lithoscytina is restored. The miomopteran Eodelopterum priscum Schmidt, 1962 is newly revised and considered as a fern pinnule. In addition, the new paraneopteran Bruayaphis oudardi gen. nov. et sp. nov. is described fromthe Upper Carboniferous of France (see Supporting Information).

“…The first, lasting until the start of the Late Carboniferous (about 323 Mya), was characterized by a scarcity of fossils and potentially limited biodiversity (19). The second phase was a major adaptive radiation during the Early-Late Carboniferous boundary, resulting in the origin of winged insects and an abundance of new insect orders (20) including the appearance of the most advanced major lineage of insects, the Holometabola characterized by an egg-larvapupa-adult development (21). By the late Paleozoic Era, the fauna had begun to acquire a strong modern cast, although the main part of the process was ushered in by the mass extinction at the end of the Permian Period.…”

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
