These results provide support for only two primary domains of life—Archaea and Bacteria—because eukaryotes arose through partnership between them.

The last universal common ancestor of cellular life is found to have predated the end of late heavy bombardment, and a timescale of life is derived, combining a reappraisal of the fossil material with new molecular clock analyses.

The results provide no support for the iconic three-domain tree of life, but are consistent with an extended eocyte hypothesis whereby vital components of the eukaryotic nuclear lineage originated from within the archaeal radiation.

It is shown that a recent analysis incorporating new genomes from uncultivated Archaea recovered a strongly supported three domains tree, consistent with a number of recent studies in which improved archaeal sampling and better phylogenetic models agree in supporting the eocyte tree over the three domains hypothesis.
Phylogenomics provides robust support for a two-domains tree of life

It is found that eukaryotes consistently originate from within the archaea in a two-domains tree when due consideration is given to the fit between model and data.

It is proposed that much of the lineage diversity previously thought to be cryptomycotan/rozellid is actually microsporidian, offering new insights into the evolution of the highly specialized parasitism of canonical Microsporidia.

- 1 October 2012
Microsporidian genome evolution appears to have proceeded in at least two major steps: an ancestral remodelling of the proteome upon transition to intracellular parasitism that involved reduction but also selective expansion, followed by a secondary compaction of genome architecture in some, but not all, lineages.

This study reveals that microsporidian genome evolution is a highly dynamic process that has balanced constraint, reductive evolution, and genome expansion during adaptation to an extraordinarily successful obligate intracellular lifestyle.
