Group of eukaryotic organisms
Chromalveolata was a eukaryote supergroup present in a major classification of 2005, then regarded as one of the six major groups within the eukaryotes.[ 3] It was a refinement of the kingdom Chromista , first proposed by Thomas Cavalier-Smith in 1981. Chromalveolata was proposed to represent the organisms descended from a single secondary endosymbiosis involving a red alga and a bikont .[ 4] The plastids in these organisms are those that contain chlorophyll c .
However, the monophyly of the Chromalveolata has been rejected. Thus, two papers published in 2008 have phylogenetic trees in which the chromalveolates are split up,[ 5] [ 6] and recent studies continue to support this view.[ 7] [ 8]
