Sea urchin eggs contain plastid-derived components linked to development
What the study found Sea urchin eggs were found to contain plastid-derived material, including chromoplast-derived carotenoid crystals and chromoplast-specific metabolites in Arbacia lixula. The authors also report plastid DNA in the eggs of 11 other sea urchins, with diatoms appearing to be the main source. Why the authors say this matters The study suggests that…

Choanoflagellate multicellularity can arise by clonal and aggregative routes
—
in Cell biologyChoanoeca flexa choanoflagellate uses both clonal and aggregative mechanisms to form reversible multicellular sheets, challenging conventional understanding of multicellular evolution.
