However, the recent whole-genome and larger mitochondrial DNA analyses revealed that Gobi and Himalayan brown bears are already diverged lineages and have a shared ancestry, the oldest lineage of all other brown bears. A 263 base-pair segment of the mitochondrial DNA was sequenced for 3 bears and a single haplotype was gained.
However, recent studies on whole-genome and larger mitochondrial DNA have demonstrated that Gobi and Himalayan brown bears are already separate lineages with a shared ancestry, representing the oldest lineage among all other brown bears.
