    It was a very #shortperiod in Earth's history, began ca. 541 million years ago and lasted only ~13-25 million years, during which giant #evolutionary leaps occurred in #animals. I.a.under influence of increased #oxygen levels, #Bilateria, primeval #Protostomia and #Deuterostomia evolved. We Tetrapoda much later derived from the latter.

  3. `By generating localized Chordin sources in the Chordin morphant background, we showed that mobile Chordin is necessary and sufficient to establish a peak of BMP signaling opposite to Chordin source. These results provide evidence for BMP shuttling in a bilaterally symmetric cnidarian and suggest that BMP shuttling may have been functional in the potentially bilaterally symmetric cnidarian-bilaterian ancestor.`

  5. Abalde & Jondelius characterize opsins and phototransduction genes in Xenacoelomorpha, identifying cnidarian-like and lineage-specific opsins.

  7. "Together, our findings suggest that the temporal decoupling of head and trunk formation, as maximally observed in head larvae, facilitated larval evolution in Bilateria. This diverges from prevailing scenarios that propose either co-option or innovation of gene regulatory programmes to explain larva and adult origins"
