The reading article talks about critics' view about a theory suggesting presence of feathers on a dinosaur fossil found in volcanic ash. The lecture dismisses the view and supporting explanations presented in reading.
First, the reading passage makes an argument, fine lines does not represent functional structure, rather formed after the dinosaur's death due to volcanic ash. The lecture counters this claim by pointing out, other fossils found at the same site of various animals does not show any sign of decomposition. In fact it shows how beautifully the structures were preserved.
Secondly, the article disputes the theory by saying, it is hard to tell what anatomical structure the lines represent as many dinosaurs donned frills and ornamental structures. However, the lecture argues that, there is difference between chemical compositions of feathers and frills. Feathers have Beta carotene. The chemical analysis of fine lines confirmed presence of beta carotene, proving those as feathers.
Lastly, the passage debates with third counter point, feathers assists with flying and maintaining body temperature. Since the lines found are on back and tail bones, doesn't qualify as feathers. The lecture scraps the claim by giving example of peacocks. Peacocks use colorful feathers on its back and tail to attract make and same analogy was applicable with the dinosaur fossil. Moreover, the professor adds, analysis on the structure revealed that the feathers were white and orange and used for display to attract mate.
In conclusion, the lecture dismisses all the doubts cast upon the theory in the reading article and says there are strong evidences to support the theory about feathers.
