Both the lecture and reading passage talks about humpback whales' migration. While the reading states the theory about how whales navigate using stars, the lecture refutes this, saying the theory is fascinating but lacks enough evidence to be true.
First of all, the reading article claims whales are intelligent and has high cognitive ability to use stars to navigate during the migration period for feeding and mating. However, the lecture argues that other animals like ducks, tend to use stars for navigation, but it's more of an instinct than intelligence. There is not enough evidence to establish the connection between overall intelligence and navigation using stars.
Next, the article states whales migrate in straight lines by orienting themselves according to external forces or objects. Birds use physical landmarks for navigation, since there are no landmarks in open oceans, whales use stars. The lecture counters this point by stating earth's magnetic filed acts as external force. In addition, whales' brains contain a chemical called bio-magnetite and it helps to orient whales using magnetic field rather than stars.
Lastly, the reading passage argues that whales display rare behavior called spy- hopping by floating on water and looking up towards sky to watch stars. The lecture refuses this claim by pointing out that, sharks also display similar behavior when they hunt. Moreover, the professor says whales exhibit spy-hopping during day when there are no stars, making the claim implausible.
In conclusion, the lecture disagrees with the theory and supporting claims presented in the reading topic and states that whales use stars for navigation is just a speculation.
