Question

Evidence has indicated that early Earth was violent place. Extremely hot temperatures, volcanic eruptions, collisions with objects from space and presence of deadly gases contributed to this hostile environment. This was not a place for living organisms. Not until Earth began to cool did the possibility of life emerge. When cyanobacteria emerged, life began to fluorish. Which of the following was the most likely trigger for the development of living organisms?

Answer 1

The emergence of cyanobacteria was the most likely trigger for the development of living organisms on early Earth.

Step-by-step explanation:

The most likely trigger for the development of living organisms on early Earth was the emergence of cyanobacteria (also known as blue-green algae). Cyanobacteria were able to withstand harsh conditions such as high temperatures and were adapted to live in anoxic environments. They began the process of oxygenating the atmosphere, allowing for the evolution of more complex life forms.
