Observe the two fish in the image. The cave fish and minnow are genetically related to each other and are similar in many ways. The cave fish lives very deep in the ocean where there is no light. It has only the remnants of eyes and is blind. Minnows live in shallow waters where the water has light. Their eye sight is important for their survival. Which statement below best describes these two fish?

• The DNA of the cave fish has changed over time to differ from the minnow. Since there is no light where the cave fish lives, it was not necessary to have working eyes. Over time, mutations occurred which proved to improve the survival of the cave fish, which is why they are now blind and have only physical remnants of eyes.

• The DNA has not mutated over time and despite all of the evidence that suggests these two are genetically similar, one has eyes and the other does not so they must not be related.

• Cave fish must have been attacked by predators, which is why they only have the remnants of eyes.

The dark moth came about because...

• The trees became dark due to pollution so the white moth needed to change color

• By chance the dark moth had a modified gene that caused it to be dark colored

• The white moth became covered in soot from the factories and turned a dark color

• Due to the soot in the air, the white moth mutated and became dark colored
