The Red Deer Cave People were the most recent known prehistoric archaic human population. Fossils dated to the Bølling-Allerød warming, between about 14,500 to c. 11,500 years ago, were found in Red Deer Cave (Maludong) and Longlin Cave in Southwest China.

Red Deer Cave People
Temporal range: Late Pleistocene,
0.0145–0.0115 Ma
Reconstructed skull
Longlin 1, a partial skull
Scientific classification
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Primates
Family: Hominidae
Tribe: Hominini
Genus: Homo
Species: Undetermined

The fossils exhibit a mix of archaic and modern features and are tentatively thought to represent a late survival of an archaic human species, or of a hybrid population of Denisovan hominin and modern human descent, or alternatively just "robust early modern humans, probably with affinities to modern Melanesians".[1]

Evidence shows large deer were cooked in the Red Deer Cave, giving the people their name.[2]

Discovery and datingEdit

 
Mandibles

In 1979, the partial skull of a cave dweller was found in Longlin Cave in the Guangxi region of China. Additional human remains were excavated from Maludong ("Red Deer Cave"; Chinese: 马鹿洞), Yunnan Province, in 1989.

In 2012, the Red Deer Cave fossils were indirectly radiocarbon dated between 14,300 and 12,600 years before present, using charcoal found in the fossil deposits. The single Longlin fossil was dated to 11,500 years before present (mean calibrated age 11,510±255 95% CI).[3]

AnatomyEdit

In spite of their relatively recent age, the fossils exhibit archaic human features.[4] The Red Deer Cave dwellers had distinctive features that differ from modern humans, including: flat face, broad nose, jutting jaw with no chin, large molars, prominent brows, thick skull bones, and moderate-size brain.[5]

ClassificationEdit

Experts are reluctant to classify the Red Deer Cave people as a new species.[5] They might represent a previously unknown archaic human lineage, or the result of mating between Denisovans and modern humans,[2] or alternatively a thoroughly anatomically modern human population with unusual physiology.[5]
