Abstract
The lengths of introns and exons in various parts of genes of vertebrates, insects, plants and fungi are tabulated. Differences between the various groups of organisms are apparent. The results are discussed and support the idea that, generally speaking, introns were present in primitive genomes, though in some cases they may have been inserted into pre-existing genes.Keywords
