一、生物进化史是生物与灾害抗争的历史我们赖以生存的地球,滋生万物,养育着人类。大自然几十亿年来以其自身不可逆转的规律发展着、前进着,星转斗移、寒来暑往。地球自从它形成的那一天起,就有无情的水、火、雷、电,地球——母亲有沧海桑田的变化,即地质学中的造山运动,这些剧变周而复始地进行着,前进着。地球上的生物大约在20—25亿年前(也有专家认为是28—30亿年)开始在地球上出现。生物经过漫长的演化过程,由低级到高级,由简单到复杂。占领了海洋、陆地、大气的每个角落,形成了生物圈。生物一出现便参与了对岩石圈、大气圈和水圈的改造。而
First, the history of biological evolution is the history of biological and disaster resistance We live on the earth, breeding all things, raising people. For billions of years nature has developed itself with its own irreversible law. Since the day it was formed, there has been a ruthless water, fire, thunder, electricity and earth - changes in the mother’s sea and sky, that is, the orogeny in geology. These dramatic changes have been going on and on and on. Organisms on Earth began to appear on Earth about 20-25 billion years ago (some experts think it is 2.8-3 billion years old). After a long evolution of biological processes, from low to high, from simple to complex. Occupied the oceans, terrestrial, every corner of the atmosphere, the formation of the biosphere. As soon as the creature appeared, he was involved in the transformation of the lithosphere, the atmosphere, and the hydrosphere. and
