They sleep on just one side of their brain at a time
Explanation:
Dolphins are different from fishes that can breathe underwater.
It is necessary for them to get to the surface of the water at intervals to breathe air.
While sleeping, dolphins allows one hemisphere of their brains fall asleep while the other half is fully conscious. This means that If the left brain is sleeping, the right eye stays open and if the right brain is sleeping, the left eye stays open.
This happens so they always know when it's time to surface and breathe and when to escape when there is trouble.

The answer depends on the interpretation and understanding of the phylogenetic trees. The image shows the rooted phylogenetic tree consisting of the various kinds of organisms. The rooting of the tree is done by looking at how closely two species are related to each other. The species within a larger branch or archae are more similar to each other than with the species of the eukarya branch. The distance between the different branches of the tree also indicate how different they are. Larger the distance, the less related they become.
