Abstract：
:Does the intron/exon structure of eukaryotic genes belie their ancient assembly by exon-shuffling or have introns been inserted into preformed genes during eukaryotic evolution? These are the central questions in the ongoing 'introns-early' versus 'introns-late' controversy. The phylogenetic distribution of spliceosomal introns continues to strongly favor the intronslate theory. The introns-early theory, however, has claimed support from intron phase and protein structure correlations.
