Polyploidy or whole-genome duplication (WGD) is a major event that drastically reshapes genome architecture and often assumed to be causally associated with organismal innovations radiations. The 2R hypothesis suggests two WGD events (1R 2R) occurred during early vertebrate evolution. However, the timing of relative divergence gnathostomes (jawed vertebrates) cyclostomes (jawless hagfishes lampreys) unresolved whether these underlie phenotypic diversification remains elusive. Here we present...
This report provides a summary of the UK's weather and climate through calendar year 2023, alongside historical context for number essential variables. is tenth in series annual 'State UK Climate' publications, published International Journal Climatology (IJC) since 2017, an update to 2022 (Kendon et al., 2023). It accessible, authoritative up-to-date assessment trends, variations extremes based on most up date observational datasets quality. Success by no means necessary result efforts...
The timing of origin eukaryotes and the sequence eukaryogenesis are poorly constrained because their fossil record is difficult to interpret. Claims fossilized organelles have been discounted on unsubstantiated perception that they decay too quickly for fossilization. We experimentally characterized pattern time scale nuclei, chloroplasts, pyrenoids in red green algae, demonstrating persist many weeks postmortem as physical substrates available preservation, a consistent with known...

The timing of the placental mammal radiation has been focus debate over efficacy competing methods for establishing evolutionary timescales. Molecular clock analyses estimate that mammals originated before Cretaceous-Paleogene (K-Pg) mass extinction, anywhere from Late Cretaceous to Jurassic. However, absence definitive fossils placentals K-Pg boundary is compatible with a post-Cretaceous origin. Nevertheless, lineage divergence must occur it can be manifest phenotypically in descendent...
The timescale of animal diversification has been a focus debate over how evolutionary history should be calibrated to geologic time. Molecular clock analyses have invariably estimated Cryogenian or Tonian origin animals while unequivocal fossils first occur in the Ediacaran. However, redating key Ediacaran biotas and discovery several crown-Metazoa prompt recalibration molecular analyses. We present revised fossil calibrations use them estimating metazoan history. Integrating across...
