Early in 2017 scientists have discovered a new family of eukaryotic bacteria in the thermal vents of Iceland. These eubacteria -named Locky and Aasgard after the Nordic Viking gods- are thought to be the source of all eukaryotic cells in the planet. True False
Solution
True. A report, published in the journal \"Nature\" in January 2017, suggests that the first eukaryotic cell emerged as a symbiotic merging between two archaeal cells. The host, Lokiarchaeota, had many eukaryotic features, while the endosymbiont, an alphaproteobacterium, was similar to current mitochondria. Recently, a superphylum of archaea, Asgard, has been discovered, which has phylogenomic and proteomic similarities between these bacteria and the eukaryotes.
