The expanding Asgard archaea invoke novel insights into Tree of Life and eukaryogenesis.

ABSTRACT: The division of organisms on the Tree of Life into either a three-domain (3D) tree or a two-domain (2D) tree has been disputed for a long time. Ever since the discovery of Archaea by Carl Woese in 1977 using 16S ribosomal RNA sequence as the evolutionary marker, there has been a great advance in our knowledge of not only the growing diversity of Archaea but also the evolutionary relationships between different lineages of living organisms. Here, we present this perspective to summarize the progress of archaeal diversity and changing notion of the Tree of Life. Meanwhile, we provide the latest progress in genomics/physiology-based discovery of Asgard archaeal lineages as the closest relative of Eukaryotes. Furthermore, we propose three major directions for future research on exploring the "
