State
This capstone traces one photosynthetic dinoflagellate lineage from its secondary endosymbiotic chloroplast origin through its SAR supergroup placement to its ecological role as a coral symbiont.
Watch for
A dinoflagellate's ecological role as a coral symbiont depends on the two-step endosymbiotic history traced here— losing sight of either the primary or the secondary event obscures why this one photosynthetic lineage ended up living inside an animal's tissue at all.
