Look deep into nature, and then you will understand everything better. Albert Einstein

We live in a designed world- nature’s and our own. Life on earth evolved over 4.6 billion years into the complex systems and cycles that support our life, and all life, on earth today. Watch Evolution of Life in 60 Seconds to see periods of activity and inactivity in the generation of life on earth. Our planet and its forms of life are all made of the stuff of stars- nature, and people, too! What is our oldest relative? Did plants or animals come first? What came before humans? When did people arrive? Use the Evolution of Life Earth Clock to see the different eras and to discover how recent human beings are to the earth. Today scientists study the interaction between our atmosphere, biosphere, geosphere, lithosphere, and hydrosphere, looking for the biodiversity of life as it exists in the air, on land, and in the waters and continues to evolve.
