Summary

Story summary

A recent study finds all complex life on Earth may trace back to Asgard archaea, with eukaryotes linked to Hodarchaeales.
Researchers analyzed hundreds of genomes to show that eukaryotes evolved from Asgard microbes adapted to oxygen-rich environments.
The findings challenge the view that Asgard archaea thrived only in oxygen-free habitats, implying a role in the emergence of complex life.
