Beetles constitute the most biodiverse animal order with over 380 000 described species and possibly several million more yet unnamed. Recent phylogenomic studies have arrived at considerably incongruent topologies widely varying estimates of divergence dates for major beetle clades. Here, we use a dataset 68 single-copy nuclear protein-coding (NPC) genes sampling 129 out 193 recognized extant families as well first comprehensive set fully justified fossil calibrations to recover refined timescale evolution. Using phylogenetic methods that counter effects compositional rate heterogeneity, topology congruent morphological studies, which use, combined other recent propose formal changes in classification Coleoptera: Scirtiformia Scirtoidea sensu nov., Clambiformia ser. nov.

Our time analyses recovered late Carboniferous origin Coleoptera, Palaeozoic all modern suborders Triassic-Jurassic families, while fundamental divergences within phylogeny did not coincide hypothesis Cretaceous Terrestrial Revolution.

Ant backbone phylogeny resolved by modelling compositional heterogeneity among sites in genomic data

Abstract Ants are the most ubiquitous and ecologically dominant arthropods on Earth, understanding their phylogeny is crucial for deciphering character evolution, species diversification, biogeography. Although recent genomic data have shown promise in clarifying intrafamilial relationships across tree of ants, inconsistencies between molecular datasets also emerged. Here I re-examine comprehensive published Sanger-sequencing genome-scale ants using model comparison methods that among-site compositional heterogeneity to understand sources conflict phylogenetic studies. My results under best-fitting model, selected basis Bayesian cross-validation posterior predictive checking, identify contentious nodes ant whose resolution modelling-dependent. show infinite mixture CAT outperforms empirical finite models (C20, C40 C60) that, CAT-GTR + G4 enigmatic Martialis heureka sister all except Leptanillinae, rejecting more popular hypothesis supported worse-fitting models, place it as Leptanillinae.

Evaluating UCE Data Adequacy and Integrating Uncertainty in a Comprehensive Phylogeny of Ants

Abstract While some relationships in phylogenomic studies have remained stable since the Sanger sequencing era, many challenging nodes remain, even with genome-scale data. Incongruence or lack of resolution era is frequently attributed to inadequate data modeling and analytical issues that lead systematic biases. However, few investigate potential for random error establish expectations level achievable a given empirical dataset integrate uncertainties across methods when faced conflicting results. Ants are most species-rich lineage social insects one ecologically important terrestrial animals. Consequently, ants garnered significant research attention, including their systematics. Despite this, there has been no comprehensive genus-level phylogeny inferred using genomic thoroughly evaluates both signal strength incongruence. In this study, we provide insight into quantify uncertainty ant tree life by utilizing taxonomically Ultraconserved Elements date, 277 (81%) recognized genera from all 16 extant subfamilies, representing over 98% described species. We use simulations resolution, identify branches less-than-expected concordance, dissect effects model selection on recalcitrant nodes. Simulations show hundreds loci needed resolve our phylogeny. This demonstrates continued role studies.

Revisiting the four Hexapoda classes: Protura as the sister group to all other hexapods

Proceedings of the National Academy of Sciences, Journal Year: 2024, Volume and Issue: 121(39)

Published: Sept. 19, 2024

Insects represent the most diverse animal group, yet previous phylogenetic analyses based on morphological and molecular data have failed to agree evolutionary relationships of early insects their six-legged relatives (together constituting clade Hexapoda). In particular, positions three early-diverging hexapod lineages—the coneheads (Protura), springtails (Collembola), two-pronged bristletails (Diplura)—have been debated for over a century, with alternative topologies implying drastically different scenarios evolution insect body plan terrestrialization. We addressed this issue by sampling all orders experimenting broad range across-site compositional heterogeneous models designed tackle ancient divergences. Our support Protura as earliest-diverging lineage (“Protura-sister”) Collembola sister group Diplura, corresponding original composition Entognatha, characterized shared possession internal muscles in antennal flagellum. The previously recognized ‘Elliplura’ hypothesis is recovered only under site-homogeneous substitution partial supermatrices. cross-validation analysis shows that site-heterogeneous CAT-GTR model, which recovers “Protura-sister,” fits significantly better than homogeneous models. Furthermore, morphologically unusual are also supported other lines evidence, such mitogenomes, comparative embryology, sperm morphology, produced results similar those study. backbone phylogeny hexapods will facilitate exploration underpinnings terrestrialization megadiversity.
