Evolutionary study of long noncoding RNA (lncRNA) repertoires and expression patterns in 11 tetrapod species identifies approximately 11,000 primate-specific lncRNAs and 2,500 highly conserved lncRNAs, including approximately 400 genes that are likely to have ancient origins; many lncRNAs, particularly ancient ones, are actively regulated and may function mainly in embryonic development.
