我们在初中生物课上学过生命起源于海洋,那么,你知道地球上最早的动物出现在什么时候?长着什么模样吗?目前发现的最早的动物化石记录,是在6.35亿~5.41亿年前的埃迪卡拉纪。科学家由此推测,动物最早的祖先可能出现在7.2亿~6.35亿年前的成冰纪。在起源后,动物经历了一系列重要的演化过程,并最终在寒武纪早期发生动物门类大爆发,占领了从浅海到深海的广阔生态空间。你想探索动物的起源吗?让我们一起到埃迪卡拉纪去看看吧!
We learned biology in junior high school biology originated in the ocean, then, you know when the earliest animals on the earth appeared and what looks like? The earliest animal fossils record is found in 635 million to 541 million years Former Eddica Karachi. Scientists speculate that the earliest ancestors of animals may appear in 720 million ~ 635 million years ago Ice Age. After its origins, the animals underwent a series of important evolutionary processes, eventually triggering a large outbreak of animal species in the early Cambrian era and occupying a vast ecological space from shallow to deep sea. Do you want to explore the origin of animals? Let’s go to Eddie Carraji to see!
