5) but preceded the emergence of eukaryotes and even LUCA.
From such a precursor, which existed prior to LUCA, the SBHM domain apparently diversified into two forms, one that covalently bound organic radicals, and another that specialized in non-covalent interactions with proteins or nucleic acids.
Eukaryotes have maintained their introns because they confer the capacity to create evolutionary novelty through exon shuffling [ 2 ] . The introns-early theory predicts that at least some of the extant eukaryotic introns are direct descendants of the primordial sequences in the LUCA [ 2 3 4 5 ] . The alternate view, "introns-late", suggests that the last common ancestor was intron-free and that spliceosomal introns have originated in eukaryotes from recent invasions by autocatalytic RNAs (e.g.
Analysis of the conserved protein superfamilies within these folds and their phyletic distribution patterns suggests that diverse versions of these domains with distinct functions were already present in LUCA.
Although the major events in the evolution of polymerases occurred at very early stages of evolution and LUCA already had an advanced DDRP resembling the extant forms, subsequent lineage-specific elaborations of considerable magnitude have occurred.
