Phylogenetic distribution of orthologs of the hsa-mir-1302 family. The phylogenetic tree was modified from the UCSC Genome Browser. Although in human there are 4 identical copies of hsa-mir-1302-2, in all other the species listed there is only one. Abbreviations: miR, miRNA; Gap, a gap in the genome; Large insertion, an insertion of more than 100 bp, except for a 17 bp insertion in the ortholog of hsa-mir-1302-4 in Pika; Ortholog not miR, the ortholog is not a miRNA; Ortholog and miR, the ortholog has been validated as a miRNA; MIR1-MIR8, the orthologs of hsa-mir-1302-1, hsa-mir-1302-2, hsa-mir-1302-3, hsa-mir-1302-4, hsa-mir-1302-5, hsa-mir-1302-6, hsa-mir-1302-7, and hsa-mir-1302-8 respectively.
