| Research Abstract |
In the relation of the four species, Haliotis discus hannai, H. d. discus, H. madaka and H. gigantes, H. gigantes had a solid boundary between the other three species. Next, the clade of H. madaka belonged to the clade of H. gigantes, and it was derived from near the root, suggesting that H. madaka arose in crossing of Haliotis discus species and H. gigante. The results of genetic relations using a microsatellite and mitochondrial DNA were different and this inconsistency was found also between local populations. It was considered to be the difference from the rate of evolution and adaptation to environment nature, and it was guessed that specialization originated in various historical events instead of one way.
