Chromalveolata is a eukaryote supergroup first proposed by Thomas Cavalier-Smith as a refinement of his kingdom Chromista, which was first proposed in 1981. It was proposed to represent the result of a single secondary endosymbiosis of a line descending from a bikont with a red alga that became the progenitor of chlorophyll c containing plastids.

Chromalveolata is a eukaryote supergroup first proposed by Thomas Cavalier-Smith as a refinement of his kingdom Chromista, which was first proposed in 1981. It was proposed to represent the result of a single secondary endosymbiosis of a line descending from a bikont with a red alga that became the progenitor of chlorophyll c containing plastids.
As of 2006, it was often regarded as one of six major clades of eukaryotes, although it is hotly debated and does not appear to be monophyletic as originally proposed.
Though several groups, such as the ciliates and the water molds, have lost the ability to photosynthesize, most are autotrophic. All photosynthetic chromalveolates use chlorophylls a and c, and many use accessory pigments.
Chromalveolates share similar Glyceraldehyde 3-phosphate dehydrogenase proteins.
Chromalveolates are not given any formal taxonomical classification, but may be considered a “kingdom”.
Specifically, recent expressed sequence tag analysis has suggested...
