The reading provides evidence to explain why humpback whales are navigating by the stars to migrate long distances, however the lecturer thinks this fascinating theory has not convincing scientific basic and These arguments, one by one, can be challenged: first, according to the reading, the high degree of complexity and intelligence of whale' brain would to make them able to use the stars for orientation. on the other hand, the lecturer argues there is no any real connection between overall between animal's intelligence and their ability to use stars for navigating as we know, some birds like ducks are inborn with instinct ability to use the stars but they are not highly intelligent. second, the author of reading claims that whales use the stars as external objects for migrating in straight lines, nonetheless the lecturer proposed the Earth magnetic field for external object and he describes that whales have a bio-magnetic substance in their brain by which they can orient themselves. third, the author of the reading describes why whales sometimes float straight up and their head are above the water. this unusual behavior is so-called spy-hopping which is rare among marine animals and could be a explanation for using the stars to navigate by whales. Nonetheless, the lecturer contraticts this idea by indicating to sharks which they use spy-hopping to look animals to hunt rather and they do not migrate. Furthermore, whales also do spy-hopping in a day which illustrates it is not a good evidence. To conclude, the cases that seem to support that whales may be navigating by the stars , one by one, be refuted by The professor.
