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.[1]
In their full autosomal genome, the Lebbo' harbor both Austronesian-related and Mainland Southeast Asian (=Austroasiatic-related) ancestries, like most ethnic groups in the western part of Insular Southeast Asia. Additionally (and – as of now – uniquely among peoples sampled from Borneo and other parts of western Insular Southeast Asia), they have a significant ancestral compontent related to Papuans.[2][3]
In a small sample of Lebbo' males (15 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%.[4] 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.[5] 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.[6] (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.[5])
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.[4]
