Kenyah people (Uma Baka' people)

The Lebbo' people (also known as the Lebu') are part of the indigenous Dayak people of East Kalimantan province (east central Borneo), Indonesia. They generally regarded themselves as a subgroup of the Kenyah people.[1]

Before the modern era, the Lebbo' people were often hunter-gatherers or horticulturalists.

Most members of the Lebbo' live in the Sangkulirang-Mangkalihat Karst range and speak the Lebu’ Kulit (or Lepu' Kulit) language, also known as Wahau Kenyah (or Waha Kenya).

Population genetics

The Lebbo' have been of great interest to geneticists, due to their distinctive population genetics; these link them link them to most strongly to the Ma'anyan people of Central Kalimantan, as well as other minorities in South East Asia and, far more distantly, to some South Asian tribal peoples and indigenous Australians. In a small sample of Lebbo' males (12 individuals) the following Y-DNA haplogroups were found C* (M130) 13.33%, K* (M9) 6.67%), K2 (M526) 13.33%, O1b1a1a1a1a (M88) 33.33%, O1a2 (M50) 26.67% and O2a1b~ (M164) 6.67%.[2] A previous study found a small percentage of Lebbo' males (two individuals) to be the only known members of the rare C1b1a2a, also known as C-B67.[3] (The less rare sibling clade C1b1a2b/C-F725 has been found in members of the Murut people in Brunei, Malay people in Singapore, Aeta people in the Philippines, and Han Chinese in China.[3])

The most common Mitochondrial DNA haplogroups found amongst a small sample of 19 Lebbo' individuals were: B4a 21.05%, B5a 15.79%, M20 15.79%, M71a2 15.79%, R9b1a1a 10.53% and E1a 21.05% out of a sample size of 19 Lebbo' people.[2]
