The professor in the lecture believes that there are strong evidences about that the lines on the Sinosauropteryx were feathers. She gives three reasons that contradict the points in the passage.
At first, she states the lines on these fossils are not due to decomposition. Because the decomposition has not observed in any fossils of animals or birds, hence these lines should not have been due to decomposition. Therefore, she concludes that these lines are real that is on the contrary of the point in the reading that these lines were created after the death of the animal.
Second, the lecture acclaims that the lines are feathers, not frills. The professor mentions that these fossils have Beta carotene in their structures. She also illustrates that feathers contain Beta carotene and frills do not have this chemical material. Then she concludes that these lines were feathers, not frills. This point casts doubt on the reading that states the lines are not feathers and can be another part of the animal.
Third, the professor explains that all the feathers are not just for the flying. She explains about peacock as an example and illustrates that peacocks have a lot of feathers on their tail and back, which are not for the flying, however these are for the attraction of the mate. She also mentions that there are some evidences that show the lines on the fossils were orange and white, therefor the line are surely feathers. That refutes the point in the passage, lines located on the backbones, so they should have been useless for the flight and were very little, hence these were not feathers.
