“…Only a few nuclear genes have been sequenced thus far to investigate phylogenetic relationships among cicadas worldwide, being EF‐1α the most extensively used and informative (Arensburger, Buckley, et al, 2004; Banker et al, 2017; Buckley & Simon, 2007; Hill et al, 2021; Lee & Hill, 2010; Marshall et al, 2008, 2016, 2018; Owen et al, 2017; Price et al, 2019; Simon et al, 2019). Nuclear genes have been shown as insufficient to resolve the phylogeny of cryptic cicada species where hybridization is suspected, even when multiple genes were used (Banker et al, 2017; Buckley & Simon, 2007; Wade et al, 2015).…”

The effect of the Messinian salinity crisis on the early diversification of the Tettigettalna cicadas

The current distribution patterns of many Mediterranean species are often a consequence of large and impactful past geoclimatic events, such as the Messinian Salinity Crisis (MSC) and the Quaternary glacial cycles. Cicadas are flying insects with poor dispersal ability, which have experienced intense local differentiation in the Mediterranean, where the genus Tettigettalna has surfaced as a biogeographic model. The genus includes 10 species with species-specific calling songs but identical morphology. All Tettigettalna species are restricted to Southern Iberia, with the exception of T. estrellae (northwest Iberia), the widespread T. argentata (mainly Iberia, France and Italy), and T. afroamissa (Morocco). With an expanded genetic dataset involving nuclear (EF1α) and mitochondrial (5′ and 3′ COI and ATP) loci, we reconstructed the phylogeny of the genus and estimated divergence dates for Tettigettalna species under a Bayesian framework. Phylogeny with the new mitochondrial dataset was in agreement with previous studies, whereas the nuclear EF1α supported T. josei and T. afroamissa as monophyletic clades but lacked resolution to resolve the remaining taxa. Some sister taxa share mitochondrial haplotypes, hinting for incomplete lineage sorting. Estimates of divergence time settled T. josei as the earliest diverging lineage, likely as a pre-or early-MSC event. As for the origin of T. afroamissa in Morocco, though time estimates could not entirely rule out post-MSC dispersal, the most likely scenario points to isolation of African Tettigettalna after the reopening of the strait of Gibraltar. The Pleistocene glaciations that followed likely impacted on the diversification of the remaining species of the genus in southern Iberia refugia.

“…Clock rates of specific genes vary across organisms due to life history and other factors (Ho and Lo, 2013). In addition to the uncertainty in the clocks themselves, other uncertainties related to model choice (Schwartz and Mueller, 2010; Andújar et al ., 2012), calibration method (Brandley et al ., 2011) and other aspects of phylogenetic analyses (Marshall, 2010; Nelson et al ., 2015) have also been discussed (Marshall et al ., 2016; Hill et al ., 2021). In the present study, we used both the clock and fossil calibrations in dating analyses of YLS and Cicadidae, aiming to achieve better divergence time estimation.…”

“…4), which is similar to that of Hill et al . (2021). Previous dating analyses of the subfamily Cicadettinae suggested that the tribe Cicadettini most possibly originated around the time of the greenhouse–ice house transition at the end of the Eocene (~41–33 Ma) (Marshall et al ., 2016; Owen et al ., 2017), which is a few million years earlier than the estimate (i.e., 33.5–28.99 Ma) in our present study (Fig.…”

“…The results are consistent with the hypothesis of Simon et al (2019), which inferred the date of origin of Cicadidae to be 99-60 Ma during the time of the main Angiosperm radiation. Hill et al (2021) estimated that the age of the Asian subclade of the subfamily Cicadinae [Clade 9 in Marshall et al (2018)] is at approximately 38-31 Ma. The age of this subclade in our analyses is 38.17-32.73 Ma (Fig.…”

Summary Previous evidence suggests that cicadas lacking Hodgkinia may harbour the yeast‐like fungal symbionts (YLS). Here, we reinforce an earlier conclusion that the pathogenic ancestor of YLS independently infected different cicada lineages instead of the common ancestor of Cicadidae. Five independent replacement events in the loss of Hodgkinia/acquisition of YLS and seven other replacement events of YLS (from an Ophiocordyceps fungus to another Ophiocordyceps fungus) are hypothesised to have occurred within the sampled cicada taxa. The divergence time of YLS lineages was later than that of corresponding cicada lineages. The rapid shift of diversification rates of YLS and related cicada‐parasitizing Ophiocordyceps began at approximately 32.94 Ma, and the diversification rate reached the highest value at approximately 24.82 Ma, which corresponds to the cooling climate changes at the Eocene–Oligocene boundary and the Oligocene–Miocene transition respectively. Combined with related acquisition/replacement events of YLS occurred during the cooling‐climate periods, we hypothesise that the cooling‐climate changes impacted the interactions between cicadas and related Ophiocordyceps, which coupled with the unusual life cycle and the differentiation of cicadas may finally led to the diversification of YLS in Cicadidae. Our results contribute to a better understanding of the evolutionary transition of YLS from entomopathogenic fungi in insects.

A robust timetree for Mammalia was constructed using the time calibration function of BEAST v1.10.4 and MEGA 11. The analysis involved the application of times of the most recent common ancestors, including a total of 19 mammalian fossil calibration ages following Benton et al. (Palaeontologia Electronica, 2015, 1–106) for their minimum ages. Additionally, fossil calibration ages for Gorilla, Pan, and a geologic event calibration age for otters were incorporated. Using these calibration ages, I constructed a geologically calibrated tree that estimates the age of the Homo and Pan splitting to be 5.69 Ma. The tree carries several significant implications. First, after the initial rifting at 120 Ma, the Atlantic Ocean expanded by over 500 km around Chron 34 (84 Ma), and vicariant speciation between Afrotheria (Africa) and Xenarthra (South America) appears to have commenced around 70 Ma. Additionally, ordinal level differentiations began immediately following the K–Pg boundary (66.0 Ma), supporting previous hypothesis that mammalian radiation rapidly filled ecological niches left vacant by non‐avian dinosaurs. I constructed a diagram depicting the relationship between base substitution rate and age using an additional function in BEAST v1.10.4. The diagram reveals an exponential increase in the base substitution rate approaching recent times. This increased base substitution rate during the Neogene period may have contributed to the expansion of biodiversity, including the extensive adaptive radiation that led to the evolution of Homo sapiens. One significant driving factor behind this radiation could be attributed to the emergence and proliferation of C4 grasses since 20 Ma. These grasses have played a role in increasing carbon fixation, reducing atmospheric CO2 concentration, inducing global cooling, and initiating Quaternary glacial–interglacial cycles, thereby causing significant climatic changes.
