Asian black bear
Biologically and morphologically, Asiatic black bears represent the beginning of the arboreal specializations attained by sloth bears and sun bears. Asiatic black bears have karyotypes nearly identical to those of the five other ursine bears, and, as is typical in the genus, they have 74 chromosomes. From an evolutionary perspective, Asiatic black bears are the least changed of Old World bears, with certain scientists arguing that it is likely that all other lineages of ursine bear stem from this species. Scientists have proposed that Asiatic black bears are either a surviving, albeit modified, form of "Ursus etruscus", specifically the early, small variety of the Middle Villafranchian (Upper Pliocene to Lower Pleistocene) or a larger form of "Ursus minimus", an extinct species that arose 4,000,000 years ago. With the exception of the age of the bones, it is often difficult to distinguish the remains of "Ursus minimus" with those of modern Asiatic black bears.

In Japanese culture, the black bear is traditionally associated with the mountain spirit ("yama no kami") and is characterized variously as "mountain man" ("yamaotoko"), "mountain uncle" ("yama no ossan"), "mountain father" ("yama no oyaji"), a loving mother and a child. Being a largely solitary creature, the bear is also viewed as "lonely person" ("sabishigariya"). Black bears feature very little in lowland Japanese folklore, but are prominent in upland Japan, a fact thought to reflect the bear's greater economic value in upland areas. According to the local folklore in Kituarahara-gun in Niigata, the black bear received its white mark after being given a silk-wrapped amulet by "yama no kami", which left the mark after being removed.
In Hindu mythology, the black bear Jambavantha (also known as Jambavan or Jamvanta) is believed to have lived from Treta Yuga to Dvapara Yuga. In the epic "Ramayana", Jambavantha assists Rama in finding his wife Sita and battle her abductor, Ravana.
