Kutanan "et al." (2020) have found F*-M89 in 50.0% (8/16) of a sample of Red Lahu, 47.1% (8/17) of a sample of Black Lahu, and 6.7% (1/15) of a sample of Lisu in Mae Hong Son Province of Thailand. All these Loloish-speaking members of F*-M89 in northwestern Thailand have been found to be quite closely related in the paternal line, with the TMRCA of their Y-DNA estimated to be 584 years before present. However, the aforementioned Y-chromosomes are only distantly related to instances of F*-M89 observed in samples of other populations of Thailand, including 5.6% (1/18) of a sample of Phuan from Central Thailand, 11.8% (2/17) of a sample of Soa from Northeast Thailand, and 29% (2/7) of a sample of Saek from Northeast Thailand. The TMRCA of the Loloish cluster from North Thailand and the Y-DNA of the Phuan individual from Central Thailand has been estimated to be 12,675 years before present. The TMRCA of the F*-M89 cluster from Northeast Thailand has been estimated to be 6,492 years before present. The TMRCA of all these F*-M89 individuals from Thailand has been estimated to be 16,006 years before present.
