It is generally well accepted that eukaryotes evolved from the symbiosis of an archaeal host cell and an alphaproteobacterium, a union that ultimately gave rise to the complex, eukaryotic cells we see today. However, the catalyst of this merger, the exact nature of the cellular biology of either partner, or how this event spawned the vast majority of complex life on Earth remains enigmatic. In recent years, the discovery of the Asgard archaea, the closest known prokaryotic relatives of eukaryotes, has been monumental for addressing
