“…We calibrated the molecular clock using exponential prior distributions for the ages of eight nodes of the tree (Ho & Phillips, 2009), based on fossil evidence (Table 1). The soft maximum bounds of the calibration priors were determined by using phylogenetic bracketing (Nguyen & Ho, 2020). The selected cockroach and termite fossils mainly followed Bucek et al (2019) Blattidae + Tryonicidae was supported by the phylogenetic analyses of Bourguignon et al (2018) and Evangelista et al (2019).…”

Cockroaches are an ecologically and economically important insect group, but some fundamental aspects of their evolutionary history remain unresolved. In particular, there are outstanding questions about some of the deeper relationships among cockroach families. As a group transferred from Blaberoidea Saussure to Blattoidea Latreille, the evolutionary history of the family Anaplectidae Walker requires re‐evaluation. In our study, we infer the phylogeny of Blattoidea based on the mitochondrial genomes of 28 outgroup taxa and 67 ingroup taxa, including 25 newly sequenced blattoid species mainly from the families Anaplectidae and Blattidae Latreille. Our results indicate that Blattoidea is the sister group of the remaining Blattodea Brunner von Wattenwyl and that Blattoidea can be divided into three main clades: Blattidae + Tryonicidae McKittrick & Mackerras, Lamproblattidae McKittrick + Anaplectidae and Termitoidae Latreille + Cryptocercidae Handlirsch. Our analyses provide robust support for previously uncertain hypotheses. The sister group of Termitoidae + Cryptocercidae (Xylophagodea Engel) is inferred to constitute the rest of Blattoidea, for the first time. Within Blattidae, Hebardina Bey‐Bienko is placed as the sister lineage to the rest of Blattidae. The subfamily Archiblattinae is polyphyletic, Blattinae is paraphyletic and Polyzosteriinae is monophyletic (Macrocercinae Roth not included); the genus Periplaneta Burmrister is polyphyletic. Based on the results of our phylogenetic analyses, we have revised these taxa. A new subfamily, Hebardininae subfam.nov., is proposed in Blattidae. Archiblattinae and Shelfordella Adelung are synonymized with Blattinae and Periplaneta, respectively: Archiblattinae Kirby syn.nov. and Shelfordella Adelung syn.nov. Our inferred divergence times indicate that Blattoidea emerged in the Late Triassic, with six families in Blattoidea diverging in the Middle and Late Jurassic. We suggest that the divergences among lineages of Asian Blattidae and Anaplectidae were driven by the uplift of the Himalayas and deglaciation during the Quaternary, leading to the present‐day distributions of these taxa.

“…To estimate the relative divergence time, a fossil calibration was applied to the phylogenetic reconstruction of the PCGs using a Coalescent Bayesian Skyline inference and relaxed clock log-normal prior (Drummond et al, 2006;Heled and Drummond, 2012;Sauquet, 2013). Following (Nguyen and Ho, 2020;Simpson et al, 2011) and the Palaeobiology Database (https://paleobiodb.org), the stratigraphically oldest confirmed fossil occurrence of P. versipora (specimen Fig. S1) was used to create a calibration prior, probability gamma distributed with a skewed peak.…”

“…For very fast-evolving organisms such as SARS-CoV-2, for which samples are obtained over a time span, the collection times provide this external information from which we can learn the rate of molecular evolution and date past events (Boni et al 2020). In groups for which the fossil record is abundant, state-of-the-art dating methods use fossil information to complement molecular data, either in the form of a prior distribution on node ages (Nguyen & Ho 2020), or as data modelled with a fossilization process (Heath et al 2014).…”
