The origin of the Chromalveolata was thought to be a secondary endosymbiosis between a bikont (cell with two flagella) and a red alga.[1] This union led to plastids containing chlorophyll c. In Cavalier-Smith's classification, the Chromalveolata was one of the six major groups within the eukaryotes.[2]
