Mean and median intron lengths in extant eukaryotic genomes and inferred mean and median lengths of introns in a hypothetical pre-LECA eukaryote. For each taxon, the genome with the highest values of mean and median lengths was chosen. The data are from the National Center for Biotechnology Information genome division (http://www.ncbi.nlm.nih.gov/Genomes/). (This figure appears in color in the online version of Journal of Heredity.)
