Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Geoarchaeota?
Summarize this article for a 10 year old
TACK is a group of archaea, its name an acronym for Thaumarchaeota (now Nitrososphaerota), Aigarchaeota, Crenarchaeota (now Thermoproteota), and Korarchaeota, the first groups discovered. They are found in different environments ranging from acidophilic thermophiles to mesophiles and psychrophiles and with different types of metabolism, predominantly anaerobic and chemosynthetic.[4] TACK is a clade that is sister to the Asgard branch that gave rise to the eukaryotes. It has been proposed that the TACK clade be classified as Crenarchaeota and that the traditional "Crenarchaeota" (Thermoproteota) be classified as a class called "Sulfolobia", along with the other phyla with class rank or order.[5] After including the kingdom category into ICNP, the proposed name of this group is kingdom Thermoproteati Guy and Ettema 2024.[6]
