The honey badger is the only member of the genus Mellivora. Although it was initially assigned to the badger group in the 1860s, it is now generally accepted that they bear very few similarities to the subfamily Melinae, instead being much closer to the marten family. Differences between Mellivora and Melinae include a different dentition. Though not related to the wolverine, which is a large-sized deviant of the marten family, the honey badger can be considered an analogous form of weasel (polecat). The species first appeared during the middle Pliocene in Asia. Its closest relation was the extinct genus Eomellivora, which is known from the upper Miocene, and evolved into several different species throughout the whole Pliocene in both the Old and New World.[4]
