Lokiarchaeon Genome Analysis Supports Hydrogen Hypothesis

[QUOTE="Ygggdrasil, post: 6007855, member: 124113"] In 2017, researchers identified a larger superphylum of archaea related to Lokiarchaeota (see [URL]https://www.physicsforums.com/threads/new-findings-about-the-evolution-of-complex-cellular-life.899972/[/URL]). I wonder if these results apply to the wider Asgard superphylum. This is an important question because it is not as if the Lokiarchaeota have stopped evolving since eukaryogenesis occurred. In the intervening ~2 billion years, the Lokiarchaeota will have undergone some evolution and might have been forced to occupy new niches as eukaryotes expanded to occupy niches previously held by Lokiarchaeota and other similar organisms. If Lokiarchaeota is indeed an obligate anaerobe as suggested by the Sousa et al. paper, it raises the question of how it would have encountered the (presumably aerobic) bacterium that would become the [URL="https://www.physicsforums.com/insights/when-did-mitochondria-evolve/"]mitochondria[/URL].
