Dog Skull 33000

January 25, 2012 by staff 

Dog Skull 33000, Researchers have uncovered a 33,000-year-old dog skull in the Altai Mountain region of Siberia in a cave called Razboinichya. This find is noteworthy for its historic value, however scientists also say it suggests modern dogs might be descended from multiple ancestors.

This prehistoric skull is the oldest known evidence of dog domestication. According to a Jan. 23 press release issued from the University of Arizona, this fossil, along with remains from an “equally ancient dog” found in a Belgian cave, jointly suggest that multiple geographic regions were domesticating dogs around the same time-frame. “In other words, man’s best friends may have originated from more than one ancient ancestor, contrary to what some DNA evidence previously has indicated,” the press release said.

“Both the Belgian find and the Siberian find are domesticated species based on morphological characteristics,” said Greg Hodgins, a co-author of the study. “Essentially, wolves have long thin snouts and their teeth are not crowded, and domestication results in this shortening of the snout and widening of the jaws and crowding of the teeth.”
