Nautilus

Life! Where did we come from? Where are we going? Out of the vastness of space a sequence of events beginning with the tiniest of life forms ignites the spiral of evolution. Through fish, plants, animals and birds the path eventually leads to mankind. A pool of life bringing water cascades from the treetops to form a pathway to a bright and hopeful future
