In the lecture, the professor discusses why the hypothesis in the passage that edmontosours migrated south to avoid wintertime is not reasonable.
To begin with, the passage claims that edmontosours lived too north to have sufficient plants for food, so they must migrate. However, the speaker refutes this by saying that in North Slope it was warm enough and had sunshine 24 hours a day in summer. So the plants were abundant and dead plants were sufficient winter.
Secondly, whilst the passage states that edmontosours migrated since they lived in herds, the lecturer points out that many animals living in herd actually do not migrate, but they get protection by doing so. Thus, it is not convincing that living in herds means edmontosours migrated.
Last, the professor argues that young edmontosaurs was incapable of running as fast as adults and they they must be accompanied by adults, which indicates that edmontosaur population is unlikely to migrate, as a response to the assertion in the reading passage that edmontosaurs could migrate simply because the adults can move really fast.
In conclusion, based on the reasons and analysis given by the speaker above, the lack of food in the north, living in herds and the wonderful locomotive power of adults can not be the evidence of the migration of edmontosours.
