最原始的生物是什么
原生生物界:最简单、最原始、最低等的动物
最原始的生物是什么
原始地球温度很高,地质非常不稳定,时时都有地震和火山喷发,空中电闪雷鸣。原始的大气的成分跟现在有很大不同,跟火山气成分差不多。其中的水分等遇冷变成雨降下来,遇到高温的地面又蒸发。水跟空中的氨气等成分,在闪电的作用下可能生成氨基酸,核苷酸等构成生命的基本有机物。后来地球渐渐冷下来,水汇集到地面形成原始海洋,有机物就溶解在原始海洋中。
有机物相互作用发生化学反应,氨基酸缩聚生成蛋白质,核苷酸则生成dna或rna,dna和rna能实现自我复制,甚至能利用氨基酸生成蛋白质。在漫长的时间里,在一次又一次的偶然中,生命就诞生了。
然而这样的生命结构比现在的病毒(病毒由dna或rna和包裹在外面的蛋白质组成,没有细胞结构)还要简单,但是经过长时间的进化,生命越来越复杂,由没有细胞变成有单细胞,再变成多细胞,越进化越复杂,最终形成了今天的样子。至于具体时间
我们也只能从一些岩石或者遗迹中推算出来
估计是40多亿年吧
