Analysis of MicroRNA Sequence Origin and Species Similarity. These 3 sources of information for our 1047 MicroRNA sequences have a significant amount of overlap (a) and include 81 that we have predicted based upon their presence in other species and other unfinished porcine genomes. Of these sequences, 454 are unique to pigs, 318 are shared among the four species (b), 55 are shared between humans and pigs but not mice and cows and 25 are shared between mice and pigs but not humans and cows
