The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided . Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn . Mont Blanc spans the French--Italian border, and at 4,810 m (15,781 ft) is the highest mountain in the Alps . The Alpine region area contains about a hundred peaks higher than 4,000 metres (13,000 ft). </P> <P> The altitude and size of the range affects the climate in Europe; in the mountains precipitation levels vary greatly and climatic conditions consist of distinct zones . Wildlife such as ibex live in the higher peaks to elevations of 3,400 m (11,155 ft), and plants such as Edelweiss grow in rocky areas in lower elevations as well as in higher elevations . Evidence of human habitation in the Alps goes back to the Palaeolithic era . A mummified man, determined to be 5,000 years old, was discovered on a glacier at the Austrian--Italian border in 1991 . </P>
