Whole genome sequencing in members of this taxonomic group has revealed the presence of DNA segments called NUMTs (“new-mights”). Thomas Cavalier-Smith classified this taxonomic group as unikonts or bikonts based on their number of flagella. The inheritance of ESCRT (“escort”) protein complexes by this taxonomic group is cited as evidence for James A. Lake’s “eocyte hypothesis.” Exemplified by the TSAR (“T-sar”) clade, members of this taxonomic group have independently evolved a process called kleptoplasty. In a 1967 paper that also explained the 9-plus-2 arrangement of flagella, Lynn Margulis proposed a theory that this taxonomic group may have evolved (10[1])after engulfing proteobacteria (10[1])via endosymbiosis. For 10 points, (10[1])name this domain of organisms whose cells have membrane-bound organelles and a nucleus. ■END■ (10[2]0[2])
