Molecular evolution: recent cases of spliceosomal intron gain?
The 'introns-late' theory holds that spliceosomal introns have been added to genes during eukaryotic evolution. Few clear examples of recent intron gains have been well documented, but two such cases have now been reported, one with possible identification of the source of the intron.
