Skiing and hunting in the Winter Olympics originated in Scandinavia and evolved from ancient skiing and hunting. About 4000 years ago, Nordic ancestors from Scandinavia carved pictures of people skiing and hunting on stones. Later, in the Middle Ages, Nordic ancestors began to incorporate skiing and hunting into military training. In modern times, Norway became the first skiing+shooting club in the world at 186 1.
