当地球别的地方被海水浸泡时，这里的大地却被甘甜的淡水包围着，因而成了中生代的生物王国；
当地球别的地方一片荒凉时，这里绽开了地球上的第一朵花，成为芬芳花果的起源地；
当地球别的地方一片沉寂时，这里飞起了地球上第一群鸟，成为古鸟的园；
当地球别的地方初等动物尚未爬行时，这里乳汁育雏的生物类群，成了哺乳动物的摇篮；
当地球别的地方悄无声息时，这里蜜蜂采花、鱼翔浅底、恐龙奔跑、鸟语花香……，成了世界独一无二的水陆空辐射的生物群落。

3. 袋狼（1936年灭绝）。近代很有名的身上附有袋子的食肉类动物，产于澳大利亚和新几内亚，通常被称为塔斯梅尼亚虎。关于袋狼的起源可追溯到“第三纪中新世”的早期。尽管这个物种已经被认为是灭绝物种，但仍有关于目击袋狼的报道。
写一篇介绍一种事物的作文老虎怎么写如下：
老虎，以其独特的橙色条纹和强大的身体，成为了丛林中的霸主。它们是大型猫科动物中的一种，以其卓越的狩猎技巧和强大的领导力在动物世界中占据了主导地位。
老虎的体型高大，肌肉发达，具有强大的咬力和爪力。其橙色的条纹和白色的腹部是它们的显著特征，这种颜色组合使得它们在丛林中能够很好地伪装自己。老虎的头部特别引人注目，一双炯炯有神的眼睛，散发出自信和威严。
老虎是出色的猎手，它们通常在夜间活动，以狩猎其他动物为生。它们有着极佳的视力和听力，能够在黑暗中察觉到猎物的存在。在狩猎时，老虎会利用其强大的爪子和牙齿，迅速而果断地制服猎物。
老虎的生活环境非常特殊，它们喜欢栖息在茂密的丛林中，如印度尼西亚的热带雨林。在这些地方，它们能够找到足够的食物和避难所。然而，随着人类活动的扩张，老虎的栖息地逐渐减少，现在已经成为濒危物种。
老虎在许多文化中都有深远的影响。在许多传说和神话中，老虎都被描绘为力量和勇气的象征。同时，老虎也是许多保护项目的关注对象。世界自然保护联盟已经将老虎列为濒危物种，并采取了一系列措施来保护它们的生存环境。
总的来说，老虎是丛林中的霸主，它们的强大和独特性使它们成为了自然界中的一道亮丽风景线。

最早的是微生物菌母，以下是对它的介绍：
5亿年前的陆地上，到处是光秃秃的山脉和大地，除了石头就是沙子，没有任何生命，也没有生命赖以生存的土壤。
直到4亿2千5百万年前，海藻才在地球大气中积累了足够的氧，形成臭氧层来保护暴露在阳光下的生命，生物才可能浮出水面。
地球上最早的生命出现在45亿年前。这时的生命是像细菌一样的东西，它只有一个细胞，今天地球上所有的动植物都是由细胞组成的。 在以后漫长的岁月中，这种单细胞的小生命遍布海洋，孤独地生活了大约20亿年。
这时的地球上空旷、寂寞，空气是有毒的，根本无法呼吸。大气中没有氧气，也没有保护生命的臭氧层，直射地面的强烈紫外线辐射只要一个小时就可以杀死绝大多数生命。
大约7亿年前，单细胞生物又演变成多细胞生物，就像今天的植物一样，它们靠光合作用吸收二氧化碳，放出氧气。
