地球的诞生距今大约有45亿年。假如把这45亿年压缩为普通一天的24小时,那么,第一批生命的萌芽,第一批陆地植物的诞生是在几点呢?第一只恐龙、第一个人类又是何时出现的呢?生命的诞生37亿年前,地球上出现了包含古细菌、蓝藻等在内的第一批单细胞生命。它们都在远古海洋中繁殖,到今天,这些最早来到地球的生命依然活跃在地球的各个角落。由此推算出,第一批单细胞生命出现在地 The birth of the earth is about 4.5 billion years ago. If we compress this 4.5 billion years into ordinary 24 hours a day, then what is the birth of the first batch of life and the birth of the first land plants? When did the first dinosaur and the first human emerge? The birth of life 3.7 billion years ago, the first batch of single-cell life including archaebacteria and cyanobacteria appeared on the earth. They all breed in ancient oceans. Today, these earliest arrivals to the earth are still active in every corner of the world. From this projection, the first single cell life appeared in the ground
