Ancient Dog Skull Shows Early Pet Domestication

Dogs are known to be the oldest domesticated animals. Common canine fossils show that they are 14,000 years old, finding one 26,500 years ago are very rare, but imagine finding one 33,000 years old is the rarest thing ever. In fact it has been discovered one 33,000 years old and new research shows that it is earliest well-preserved pet dog. It has been found in Siberia’s Altay Mountains. It has been discovered in the 1970’s but know new researched has searched morein depth.
In a much expanded historical record, scientists are trying to understand how and when wolves evolved into dogs, an evolution which could last from 50 to 100 years. Kuzmin and colleagues recently used radiocarbon dating to state how much the skull and the jaw was old. It was tested in three laboratories. Each lab confirmed that the age was around 33,000 years old.

Other artifacts found at the site suggest that hunters used space for something, and it's likely the dogs were their pets before death. Cold temperatures and non - acidic soil found in the cave is though that there were kept kept the dog's remains after decaying.
The team compared the Russian skull with modern domesticated dog, wolves and early doglike canine animals that lived before 26,500 years ago.

Since it isn’t a fully domesticated dog, it has some similarities with wolves and foxes. Kuzmin and his colleagues also did not found any likenesses to ancient or modern wolves or to dog breeds found somewhere in Russia. The discovery has discovered that this dog has began its association with humans independently, unlike the DNA proves.

In general, dogs likely became domesticated when during theStone Age wolves began to hang around Stone Age people. Animals who were more comfortable with humans, changed over time. It eventually changed their body: size, reproductive patterns and shapes, turning them into dogs. "The somewhat curious and less fearful 'first founders' became even more so as they interbred amongst themselves," Crockford said.
