高度认识古生物化石的价值 地球至今已有４６亿年的历史。人类根据现代生物的研究和对地层中保存的古生物化石的研究结果说明，地球早期是没有生命的，直到３２亿年以前，海洋中才有了低等的菌藻类生物，经过３２亿年的演化至今，生命才演化出植物界和动物界，从水生到陆生。 A high degree of understanding of the value of paleontology fossils Earth has a history of 4.6 billion years. According to the study of modern biology and the study of paleontological fossils preserved in strata, human beings have shown that there was no life in the early stage of the earth. Until 3.2 billion years ago, there were only low-grade bacteria and algae in the oceans. After 3.2 billion years of evolution So far, life has evolved flora and fauna, from aquatic to terrestrial.
