Cyanobacteria were the first photosynthetic organisms. How were they responsible for allowing higher life forms to evolve? A. They released oxygen, which mixed to form iron, and later ferrous oxide, in the air. B. They released carbon dioxide, which evolving animals needed. C. They released oxygen, which created the ozone layer, resulting in reduced mutation rate.

I think the correct answer from the choices listed above is option C. Cyanobacteria is responsible for allowing higher life forms to evolve by releasing oxygen, which created the ozone layer, resulting in reduced mutation rate.
