GeoWorld - Geological clock

Geological clock Bild 194

The earth's history in 12 hours.
Planet Earth is starting out as a fire ball with no protection from harmful UV radiation. The development of the ozone layer of the atmosphere makes the development of life on earth possible. Greenhouse gases prevent the earth from getting too cold and then, 56 minutes to 12 o'clock, life on land develops rapidly. Modern man only appears within the last 2 seconds! How long will our human life-form last for, we might ask!
