@em.myco: Just like the Norse God, Loki the Asgard is a shape-shifter. And its constantly changing morphology might explain why animals have organs and why plants photosynthesise. Note: Asgards were originally called “Lokiarchaeota”, but this has since changed to “Promethearchaeaceae” which I cannot pronounce. Sources: [1] Radler et al.
