SAR supergroup
Eukaryotes superphylum / From Wikipedia, the free encyclopedia
The SAR supergroup, also just SAR or Harosa, is a clade of Eukaryotes that includes stramenopiles (heterokonts), alveolates, and Rhizaria.[2][3][4][5] The name is an acronym derived from the first letters of each of these clades;[lower-alpha 1] it has been alternatively spelled "RAS".[6][7] The term "Harosa" (at the subkingdom level) has also been used.[8] The SAR supergroup is a node-based taxon.[6] The TSAR clade also includes the Telonemids.[9]

Members of the SAR supergroup were once included under the separate supergroups Chromalveolata (Chromista and Alveolata) and Rhizaria, until phylogenetic studies confirmed that stramenopiles and alveolates diverged with Rhizaria.[10] This apparently excluded haptophytes and cryptomonads, leading Okamoto et al. (2009) to propose the clade Hacrobia to accommodate them.[11]
A 2021 analysis places Alveolata and Stramenopiles (Heterokonts) in Halvaria, as sister to Rhizaria.[12]
