KUNMING, Nov. 16 (Xinhua) — Dogs have been humankind's faithful companions for millennia, and a new study of ancient dog DNA reveals how deeply intertwined their histories are with ours.
An international team led by Chinese scientists has discovered that dogs have faithfully followed human migrations across Eurasia for nearly 10,000 years.
They analyzed the genomes of 73 ancient dogs, including 17 ancient domestic dogs. This resulted in a map of the evolution of the domestic dog lineage from East Asia to the Western Eurasian steppes. Specifically, the study yielded the first genomes of 14 ancient Chinese domestic dogs. The results were published Friday in the journal Science.
Both the Northeast Asian origin of Chinese dogs and the western origin of steppe dogs reflect human migrations. The study shows that Neolithic dogs on the early Eurasian steppes were related to Eastern European hunter-gatherers, while Bronze Age dogs were related to Iranian farmers and Caucasian hunter-gatherers.
The study not only confirms the millennia-old connection between humans and dogs, but also reflects the interconnectedness of ancient civilizations.
The researchers say this approach could be applied to horses, cattle, small ruminants, and other domesticated animals, further clarifying their role in human history. -0-
