In the 4.6 billion years of the earth, traceable creatures began about 3.5 billion years ago with blue-green algae. At the beginning of the Phanerozoic Cambrian period 600 million years ago, all kinds of creatures have successively entered the stage of life evolution, contending with each other and showing their magical powers. The most representative ones are the trilobites in the Paleozoic era, the dinosaur dynasty in the Mesozoic era, and the mammals in the Cenozoic era developed rapidly. Walking on this evolutionary history trail, you will experience 1.8 million years of the earth's evolution history for every step of three tiles. From the clues of the fossils, paleontologists have composed a climax of the life history movement. Except for the magnification of the archaic blue-green algae and single-celled protozoa, the main organisms of the qualitative ages are all carved out with their real size, so that everyone can experience the miracle of life evolution.
If the entire history of the earth from Archean to the present is counted as 24 hours, according to the radioisotope dating method, the time of each generation on the earth’s age clock is calculated as follows: Precambrian for 17 hours, Paleozoic for 4 hours, Mesozoic 2 hours, 1 hour for the Cenozoic era, human beings of the spirit of all things appeared millions of years ago, which is equivalent to the last 1 minute that appeared in the history of life on the earth. It is really a moment in eternity, and it is insignificant.
在地球46億年的悠長歲月中，有跡可尋的生物大約始自35億年前的藍綠藻。6億年前的顯生元寒武紀開始，各類生物接續步入生命演化的舞臺，爭奇鬥豔，各顯神通。其中最具代表性的分別是古生代的三葉蟲、中生代的恐龍王朝與新生代的哺乳動物大肆發展。漫步在這條演化史步道上，每跨出三塊地磚的一個步幅，您將經歷180萬年的地球演化史。從化石的蛛絲馬跡，古生物學家譜出了高潮迭起的生命史樂章。在這裡除了太古代的藍綠藻和單細胞原生動物經放大之外，各地質年代的主要生物都用真實的大小刻劃出來，讓大家體會生命演化的奇蹟。
如果將地球的全部歷史，從太古代起到現在為止算作24小時，根據放射性同位素定年法，計算出來各代在地球年齡鐘錶上的時間是:前寒武占17小時，古生代4小時，中生代2小時，新生代1小時，萬物之靈的人類出現於百萬年前，相當於最後的1分鐘才出現在地球生命史上，真是永恆中的一瞬，微不足道了。
