Tianyuan man (Chineset 田園洞, s 田园洞, p Tiányuándòng Rén) are the remains of one of the earliest modern humans to inhabit East Asia. In 2007, researchers found 34 bone fragments belonging to a single individual at the Tianyuan Cave near Beijing, China.[1] Radiocarbon dating shows the bones to be between 42,000 and 39,000 years old, which may be slightly younger than the only other finds of bones of a similar age at the Niah Caves in Sarawak on Borneo.

Isotope analysis suggests that a substantial part of the diet of these individuals came from freshwater fish.[2]

DNA tests published in 2013 revealed that Tianyuan man is related "to many present-day Asians and Native Americans".[3][4][5][6][7] He had also clearly diverged genetically from the ancestors of modern Europeans.[4] He belonged to mitochondrial DNA haplogroup B.

Tianyuan man exhibits a unique genetic affinity for GoyetQ116-1 from Goyet Caves that is not found in any other ancient individual from West Eurasia.[8]
