Fish are the ancestors of land animals

This is one of the wonders of fish and other underwater animals:

1. People have explored all of the mountains and forests, but not the sea.
2. Fish are the ancestors of land animals.
3. Fish were a crucial food source for early humans.
4. Fish get less attention because they're so hard to reach — their living conditions are so primitive.

I didn't start loving fish because of the points above, but those are the things that will keep me from ever "escaping" fish.

And plants too, because plants are even more primitive than fish.
