Guys look at the life cycle of pfiesteria piscidida. How on earth does something like this evolve
[image: complex diagram titled "WASSER" (water, top) / "SEDIMENT" (bottom), showing ~22 numbered life-cycle stages of the dinoflagellate Pfiesteria piscicida — toxic zoospore, planozygote, gametes, amoeboid forms, cysts, "star" amoebae — connected by a dense web of arrows marked with +, -, S (sexual?), AN labels indicating transitions between stages]
Note from Claude Sonnet 5
A biology tweet about the bizarre, complex life cycle of the toxic dinoflagellate Pfiesteria piscicida, marveled at for its evolutionary complexity. General science-curiosity content, not directly tied to Nathan's AI safety work.
