Biology:Heimdallarchaeum
"Candidatus Heimdallarchaeum" is a genus of archaea that in turn forms a distinct group within the Promethearchaeati kingdom.[1] Named after the mythical Norse god, Heimdall, one of the sons of Odin, it is considered the closest relative of eukaryotes.[2][3] The first specimens were discovered by a team of microbiologists at the Uppsala University, Sweden[4] from the marine sediments at Loki's Castle (hydrothermal vents in the mid-Atlantic Ocean) and Bay of Aarhus (a waterway in Denmark), and some other species from Auka hydrothermal vent field in the Pacific Ocean.[5] Its class, "Candidatus Heimdallarchaeia" is the group of archaea that eukaryotes emerged. A later study reports that their newly developed data shows that the promethearchaeon ancestors of eukaryotes are rooted in a group older than the "Candidatus Heimdallarchaeia.[6] The genus and its family, order and class are not recognized by LPSN as "pro-correct".[7]
