Posts Tagged ‘Yakutian wol’

yakutian megafaunal wolf

The Siberian Times reports that the head of a massive wolf was discovered in the permafrost in Yakutia (Sakha Republic of Russia).  The head includes much of the soft tissue, as well as its golden-colored fur. The head is 40 cm (15. 7 inches long), which is pretty large when compared to modern wolf specimens.

Researchers in Russia and Japan will be examining the DNA from the soft tissue to see where it fits in modern wolf and dog phylogeny of which there are still many questions.

This wolf is a good example of what have been termed “megafaunal wolves,” very large gray wolves that lived during the Pleistocene. Robert Wayne of UCLA, a leading canid molecular geneticists, thinks that some form of Pleistocene megafaunal wolf is the progenitor of the domestic dog.  These wolves would have been expert hunters of large bison, reindeer, and horses, and they may have been semi-nomadic, following large herds of ungulates across the steppes and taiga. These semi-nomadic wolves would have been quite easily attached to humans, who were hunting and traveling in much the same way.

Also of note, this wolf has golden colored fur.  In 2015, I postulated a speculative hypothesis that the original Pleistocene wolves were more often golden in color, rather than gray.  When humans started hunting wolves extensively during the Neolithic and into modern times, wolves that were gray were selected for because they could more easily hide from human hunters. Gray color in the dead of winter in many European and Western Asian forests would have been great camouflage against the winter tree trunks and undergrowth of the forest.

Some wolves, especially tundra wolves from northern Russia and Finland, are still often golden in color, as are those in Central Asia.

Golden sable color is quite widespread in domestic dogs, but it is far less common in wolves. So it is quite possible that this coloration is so dominant in domestic dogs because the wolves that gave rise to them were this color.

This massive wolf with golden fur certainly adds some credence to my speculations, but only time will tell what this ancient, massive wolf’s head has in store for us.

But is an amazing find. No doubt about it!

Update: Researchers in Sweden, not Japan or Russia, will be examining its DNA.
