A well-preserved 33,000 year old skull belonging to a dog in the early stages of domestication was found in the Atal Mountains of Siberia. Dogs and humans have long enjoyed a unique relationship – with dogs theoretically being the earliest animal domesticated. Interestingly, canines are the only universally domesticated animal – wherever you find humans, you find dogs (the same can not be said of cats, horses, pigs, etc).
While domesticated dogs were instrumental to the survival of humans in the region, the peoples of the Altal Mountains appear to have abandoned their animals towards the end of the ice age – possibly due to a greater scarcity of food.
