Haplogroup	n	TMRCA	HPD	Origin
HPD: 95% highest posterior density (HPD) confidence interval. Origin refers to most likely origin of haplogroups inferred as most favorable scenario that considers both genome sampling chronology and regional genome variation. Time of the most recent common ancestor (TMRCA)
