Answer:
The condition of the Earth had to become favourable before it could support any form of life.
The formation of the different layers around the earth like the ozone layer was necessary before life could originate. Primitive species such as some prokaryotes were able to live in hydrothermal conditions during the initial times. With the passage of time, as the concentration of oxygen increased due to photosynthetic prokaryotes, situations became favourable for eukaryotic organisms to arise.
I believe it is the second one not 100% sure so don't blame me if you fail.
Atlantic cod is a special type of marine fish from the family Gadidae. It is a commercially important fish because it is consumed by humans. The Atlantic cod lives in the cold waters and in the deep seas throughout North Atlantic. The Pacific cod on the other side lives in the northern Pacific.
