WebLokiarchaeota and the eukaryotes probably share a common ancestor, and if so, diverged roughly two billion years ago. Evidence for common ancestry, rather than an evolutionary shift from Lokiarchaeota to eukaryotes, is found in analysis of fold superfamilies (FSFs). Fold super families are evolutionarily defined domains of protein structure.
