Evosea is a diverseclade ofamoeboidprotists discovered throughmolecular analyses. Along withTubulinea andDiscosea, Evosea is one of the three major groups withinAmoebozoa, an important clade ofeukaryotic organisms. It contains unicellular organisms that display a wide variety of life cycles and cell shapes, includingamoebae,flagellates and different kinds ofslime molds.

Evosea is astrongly supportedclade ofeukaryotes containing four large groups ofamoebozoans:Eumycetozoa or "true" slime molds,^[3]Variosea,Cutosea andArchamoebae. It is defined on anode-based approach as the least-inclusive clade containingDictyostelium discoideum (a true slime mold),Protostelium nocturnum (a variosean),Squamamoeba japonica (a cutosean), andEntamoeba histolytica (an archamoeba).^[1]

Within Evosea, organisms can vary across almost the entire range ofmorphologies seen in Amoebozoa. Many members have complexlife cycles that includeamoebae,flagellates andfruiting stages. Some species appear to be exclusively flagellates, with no amoeboid features.^[2]

Evosea is a clade discovered in 2017 through aphylogenomic study by Senghuo Kang and coauthors, published in the journalMolecular Biology and Evolution.^[1] Since its discovery, it has been supported by independent analyses.^[4][5][6] As of 2019, it is accepted by the International Society of Protistologists as part of the moderncladistic classification of eukaryotes.^[2] The name 'Evosea' is partly anacronym of the major members of the clade:Eumycetozoa (E),Variosea (v),Squamamoebidae andSapocribridae (s), andArchamoebae (a).^[1]

Evosea is composed of twosister clades:Cutosea, a small group of solitaryamoebae, andConosa, a larger group that contains thearchamoebae,true slime molds andVariosea. Evosea, along withTubulinea andDiscosea, compose the entirety ofAmoebozoa. The branching order of these threebasal groups is still unresolved: either Evosea groups with Tubulinea (in a clade known as Tevosa),^[1] or with Discosea (in a clade called Divosa). The followingcladogram is based on a 2022 analysis, which resulted in the Divosa hypothesis:^[6]
