This 18 June 2018 video says about itself:

Phylogenomic-wide studies of evolutionarily conserved structures of protein domains suggest Archaea is the first domain of life to diversify from a stem line of descent and co-evolve with ancestors of Bacteria and Eukarya. The proposed co-evolutionary scenario by J. T. Staley and G. Caetano-Anollés challenges popular cell fusion and two-domain of life scenarios derived from sequence analysis.

Scientists identify rare evolutionary intermediates to understand the origin of eukaryotes

September 11, 2019

Summary: A new study provides a key insight into a milestone event in the early evolution of life on Earth — the origin of the cell nucleus and complex cells. Scientists peered deep inside current living cells, known as Archaea – the organisms that are believed to most closely resemble the ancient intermediates…
