Whole genome duplication in Brassica rapa is accompanied by both expansion of the circadian transcriptome and widespread temporal reconfiguration of gene regulatory networks consistent with subfunctionalization among pairs of paralogs.

Single-cell transcriptomic analysis of developing retinal ganglion cells in mice suggests that their diversification into 45 discrete types occurs via the gradual restriction of multipotential precursors.

Phylogenomics of sea urchins clarifies their origins and diversification history, reveals surprising discrepancies with their rich fossil record, and serves as basis to explore the sensitivity of time calibration analysis.

Neotropical outstanding biodiversity emerged from sustained rates of species accumulation over time, although, for some periods, tetrapods were less successful than plants in keeping pace with a changing environment.

Treating color patterns in a geometric morphometrics framework reveals rapid rates of color evolution that are explained by a combination of intrinsic organismal features (color variation among patches) and geography within a cosmopolitan radiation of birds.

The common ancestor of extant mammalian coronaviruses originated recently in a bat species and their diversification occurred via preferential host switches rather than through codiversification with mammals.

A novel regulatory model for the diversification of cardiac cell subpopulations in Drosophila is established by linking epidermal growth factor signaling with differential activities of key transcription factors.

Phylogenomics reveals the timeline over which marine bacteria and archaea colonized the oceans and shows the geological context of their diversification.

Evolutionary novelty is promoted by a macroevolutionary pulse of developmental plasticity, but is enhanced by secondary fixation, which permits developmental character release and further morphological exploration.

Evolution of multiple closely related strains with host-pathogen-like interactions but only one niche and no tradeoffs, can give rise to a spatiotemporally chaotic ecological state that continually diversifies even with generalist mutations that slow the evolution.
