Lebbo' people

The Lebbo' people are part of the indigenous Dayak people of East Kalimantan and North Kalimantan, Indonesia.
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 a variety of the Basap language.

Population genetics

In their full autosomal genome, the Lebbo' harbor both Austronesian-related and Mainland Southeast Asian ancestries, like most ethnic groups in the western part of Insular Southeast Asia. Additionally, they have a significant ancestral compontent related to Papuans.
In a small sample of Lebbo' males the following Y-DNA haplogroups were found: C* 13.33%, K* 6.67%, K2 13.33%, O1b1a1a1a1a 33.33%, O1a2 26.67%, and O2a1b~ 6.67%. A previous study found a small percentage of Lebbo' males to be the only known members of the rare C1b1a2a, also known as C-B67. According to a study by the same team of researchers published in 2022, C-B67 also has been found in one individual from Lembata and four individuals from Flores, both of which are islands in East Nusa Tenggara, Indonesia.
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.
