A team of scientists has discovered the oldest known dog species on Earth.
The new species, the Dogo Argentino, was discovered in a cave in the mountains of Xinjiang’s Xinjiang Uygur Autonomous Region.
This ancient species has a long history of evolution and domestication, the team says in a statement.
They say it is likely that it is the earliest known dog in the world.
The researchers say they will now be studying how this ancient dog came to be, and how it interacted with its environment, including humans, before becoming extinct.
“The oldest known ancient dog, the Yuxin-Xiongjiang Dogo, lived in China’s far north of the Yangtze River Basin at least 4.5 million years ago.
This was the oldest recorded case of dog domestication in the Yanomami people, a group that predates the Yaxian people who dominate today’s Yaxia region in Central China,” the team explains.
The team’s findings were published in the journal Nature Communications.
Previous research has shown that the Yoxians, who dominate parts of China’s Xin-jiang region, are descendants of a prehistoric group that inhabited the region around 4.4 million years BC.
That ancient group lived alongside their ancestors in a network of caves, which the team believes were used by dog domestications to test the dog’s loyalty.
The cave in question dates to around 4,000 years ago, which is more than half a million years after the Yucatán people first started colonizing the area, according to the team.
This research was conducted by a team of researchers from the Chinese Academy of Sciences and the Chinese National Science Foundation.
