假如有一天,人类真的发明了时空穿梭机,来到三亿多年前的泥盆纪晚期,会看到这样一幅情景——在这被称为“鱼的时代”里,随着气候的变迁,湖泊日渐干涸,水质开始变坏,生活在水中的一些鱼类只好拖着细长的身体,靠鳍的支持爬上陆地去寻找新的水源。裸蕨植物的后代——石松、楔叶和真蕨植物大量出现,形成小规模的蕨类群落,大地出现了一点绿色,为陆生动物的发展提供了条件。
If one day, mankind really invented the space-time shuttle, to the late Devonian of 300 million years ago, we will see such a scene - in this so-called “fish era”, as the climate As the lakes dried up and the water quality began to deteriorate, some fish living in the water had to drag their slender bodies and climb up the ground to find new sources of water with the support of the fins. Naked ferns descendants - stone pine, wedge leaves and true fern plants appear in large numbers, forming a small fern community, the earth appeared a little green, provided the conditions for the development of terrestrial animals.
