Combining fossil-based and molecular calibrations with data on horizontal gene transfer events, the authors develop a time-calibrated phylogeny of Fungi. This timescale, which integrates analytic uncertainties, suggests an older age of crown Fungi (1,401–896 million years ago), as well as a minimum age for ancient interactions involving fungi and the algal ancestors of embryophytes in terrestrial ecosystems (1,253–797 Ma).

We investigate the evolution of microbial metabolisms from the last universal common ancestor to the extant biota through comparative phylogenomics, reconciling the evolution of the genes that underpin metabolic pathways with a time-calibrated tree of ...

The evolution of wings and flapping flight was integral to the radiation of Pterygota, but little is known about the factors underpinning the morphological disparity of insect wings. We use a theoreti...

The timing of the origin of crown-angiosperms exemplifies the impact of competing approaches to establishing evolutionary timescales. Fossils of unequivocal crown-angiosperms are not known from before...

The study of the origins and evolution of multicellularity in different lineages has recently captured the attention of many research groups and is fueling the generation of numerous innovative resea…

Rangeomorphs are some of the oldest complex macroscopic fossil organisms. Here, the authors describe a population of rangeomorphs with two, spindle-shaped fronds from Mistaken Point, Newfoundland, mod...

The term “reviewer fatigue” has become only too familiar in scientific publishing. This editorial discusses how we can ease the burden on reviewers to make the peer review system more sustainable, whi...

Abstract. The radiation of tetrapods during the Devonian and Early Carboniferous was associated with a transition from aquatic to terrestrial environments,
