Asian black bear
species of mammal
The Asian black bear (Ursus thibetanus), also known as the Asiatic black bear, moon bear and white-chested bear, is a medium-sized bear species native to Asia that is largely adapted to an arboreal lifestyle. It is distributed from southeastern Iran, Pakistan, India and the Himalayas to mainland Southeast Asia, the Korean Peninsula, Taiwan, China and the Russian Far East to the islands of Honshū and Shikoku in Japan. It is listed as vulnerable on the IUCN Red List, and is threatened by deforestation and poaching for its body parts, which are used in traditional medicine.
Taxonomy
Ancestral and sister taxa
Biologically and morphologically, the Asian black bear represents the beginning of the arboreal specializations attained by sloth bears and sun bears. It has karyotypes nearly identical to those of the five other ursine bears, and has 74 chromosomes. It is considered the least derived of the Old World bears. It is either a surviving, albeit modified, form of Ursus etruscus, specifically the early, small variety of the Middle Villafranchian or a larger form of Ursus minimus, an extinct species that arose 4 million 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 the modern Asian black bear.
The Asian black bear and the American black bear are thought to have genetically diverged 3 million years ago, though genetic evidence is inconclusive. Both the American and Asian black species are considered sister taxa and are more closely related to each other than to the other bear species.
Begin with the source’s own compact description: “Asian black bear” is species of mammal. The dossier treats that line as a proposition to test through Asian, black and bear, not as a finished interpretation.
Why this record matters
The phrase “species of mammal” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 20, 2026. The linked authority identifier is Q124410. The Library of Congress control number is sh85119680. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
