The chain began with the simple molecules found in the early cloud dusts, and culminated with the building blocks of life from which life on Earth first sprang. The chain leading to life.这条链条从早期云尘中发现的简单分子开始，到形成生命的基石，地球上的生命就是从这些基石开始萌芽的。一条生命...
gases, and water, all of which do not originate from living organisms. These spheres interact with each other and influence the Earth’s processes, shaping the environment in which life exists.

Some marine protozoans (single-celled organisms), called foraminifera, have shells that tell the temperature of the water where the animal lived. By studying the chemical make-up of these tiny fossils, the temperatures of prehistoric seas can be found, and changes in the ocean temperature can ...
