Abstract:
Close analysis of intron phase - the position of introns within codons - is claimed to provide novel evidence supporting the view that introns predate the divergence of bacteria and eukaryotes and, via 'exon shuffling', played a crucial role in protein evolution. But just how compelling is this evidence?
