Supergrup SAR: Perbedaan antara revisi

'''Sar''' atau '''Harosa''' (informal '''supergrup SAR''') adalah [[klad]] yang mencakup stramenopila ([[heterokontophyta]]), [[alveolata]], dan [[rhizaria]].<ref name="pmid19174147">{{cite journal |author=Archibald JM |title=The puzzle of plastid evolution |journal=Curr.

Anggota supergrup SAR yang pernah dimasukkan di bawah supergrup terpisah [[Chromalveolata]] dan [[Rhizaria]], sampai studi filogenetik menegaskan bahwa stramenopila dan alveolata menyimpang bersama dengan rhizaria. Ini tampaknya mengecualikan [[haptophyta]] dan [[cryptomonad]], membuat Okamoto ''et al.'' (2009) mengusulkan klad [[Hacrobia]] untuk menampung mereka.<ref name="burki2014">{{cite journal|author=Fabien Burki|year=2014|title=The eukaryotic tree of life from a global phylogenomic perspective|journal=Cold Spring Harbor Perspectives in Biology|pages=1&ndash;171–17|doi=10.1101/cshperspect.a016147 |url=http://cshperspectives.cshlp.org/content/6/5/a016147.full|volume=6}}</ref>
