Phylogenetic distribution of intron positions in alpha-amylase genes of bilateria suggests numerous gains and losses.

Most eukaryotes have at least some genes interrupted by introns.While it is well accepted that introns were already present at moderate density in the last eukaryote common ancestor, the conspicuous diversity of intron la rams crop top density among genomes suggests a complex evolutionary history, with marked differences between phyla.The question
