Local origin or external input: modern horse origin in East Asia.

ABSTRACT:

Background

Despite decades of research, the horse domestication scenario in East Asia remains poorly understood.

Results

The study identified 16 haplogroups with fine-scale phylogenetic resolution using mitochondrial genomes of 317 horse samples. The time to the most recent common ancestor of the 16 haplogroups ranges from [0.8-3.1] thousand years ago (KYA) to [7.9-27.1] KYA. With combined analyses of the mitochondrial control region for 35 extant Przewalski's horses, 3544 modern and 203 ancient horses across the world, researchers provide evidence for that East Asian prevalent haplogroups Q and R were indigenously domesticated or they were involved in numerous distinct genetic components from wild horses in the southern part of East Asia. These events of haplotypes Q and R
