CHENGDU, Dec. 15 (Xinhua) — A new archaeological study published Thursday in the journal Science Advances indicates that residents of the Southern Qinghai-Tibet Plateau Cross-breeding yaks and cows (cross-breeding) since at least 2,500 years ago
Crossbreeding between local yaks and cattle is known. Production of hybrid animals that combine the yak’s tolerance for extreme environments. compatible with the cow’s ability to produce meat and milk
A team of researchers from Sichuan University (Sichuan), Northwest A&F University and Washington University in St. The remains of 193 yaks, cows and hybrid animals recovered from excavations at the Bangga ancient site in Shannan City were collected and analysed. which is about 2,350-2,700 years ago
Archaeologists have discovered the remains of more than 10,000 mammals dating from 2,200-3,000 years ago from the Pangka area. Pangka is a large and complex group of prehistoric stone structures. Located approximately 3,750 meters above sea level.
Genetic studies reveal that Cattle in the Panga area are genetically 12 to 20 percent similar to locally farmed yaks, while the ancestors of modern yaks lived on the Qinghai-Tibet plateau. Influenced by ancient cattle This genetic exchange shows that ancient Tibetans were already taking advantage of yak-cow crossbreeding at that time.
Furthermore, the DNA of cattle from the Panka area is similar to that of more ancient taurine cattle from northwestern China. This indicates that taurine cattle were likely brought to the Panga region from northwest China.
Livestock production Including barley and wheat cultivation in the Pangka area. It reflects that a diverse lifestyle combining agriculture and animal husbandry in the southern Qinghai-Tibet Plateau was formed about 2,000-3,000 years ago.
