Method (1st primary source:) Researchers examined functional and evolutionary patterns in the recently constructed set of 5,873 clusters of predicted orthologs (eukaryotic orthologous groups or KOGs) from seven eukaryotic genomes
Comments The prokaryote-to-eukaryote transition involved the origin of a multiplicity of new complex traits underpinned by some 3,000 new protein families (primary sources). 3,413 eukaryotic orthologous groups according to 1st primary source.
