why the wholes use the stars for navigate?
The reading and the listening lecture talk about the way that humpback whale uses to migrate. While the reading claims that those animals use the stars for navigation. The lecturer refutes this idea by providing refuting clues.
First of all, the reading states that humpback seems to be intelligent to use stars to navigate. Also, their brain is so complex giving them well developed cognitive ability to use the stars as a guide. The lecturer says that there is no connection between the intelligence and the using of stars. He states that ducks navigate by stars but it is not a clever animal and this property just borns with some animals.
In addition to that, the reading claims that the humpback maintains their movement in the straight direction because they orient themselves by stars, they provide them with external signs to keep that way of navigating. The professor counters this by saying that those animals have magnetite piece within their brain that it is sensitive to the earth magnetic, so this helps to direct them a straight way.
Lastly, the reading states that these wholes raise their head above the water to see the stars then they back to water because also they use the Phy-hopping to takes information from the sky to navigate. The professor claims that there are many animals like sharks use the Phy-hopping to hunt other animals, although they do not migrate. So it is not necessary to use this Hopping to follow the stars information.
