Relationships. The. Evidence. The. Behavior. The. In the text, "Shedding Light on the Dinosaur-Bird Connection" the author demonstrates these three assertions. These explain the similarities and the way dinosaurs and birds are affiliated. The relationship between dinosaurs and birds is very analogous. Dinosaurs have gone extinct, but birds have descended from them. For instance, "Birds are living dinosaurs, and they are remarkably similar to their closest extinct relatives, the non-bird theropod dinosaurs." Birds are now the new dinosaurs, but they are smaller. Stating that, "The group called dinosaurs includes the extinct dinosaurs and all their living descendants. All its members, including living birds, descended from the very first dinosaur—their …show more content…

While discussing relationships, the authors also include evidence. In order to make a claim, evidence is needed for the reckoning. Indicating that, "When scientists study living animals, they can look at behavior, morphology, embryology, and DNA." It's hard finding evidence on a long extinct animal, which causes paleontologists to work harder. For example, "So understanding extinct animals and how they are related to living ones takes a special kind of detective work." Paleontologists use the clues found in ancient rocks: fossilized bones, teeth, eggs, footprints, teeth marks, and even dung." ("Shedding Light on the Dinosaur-Bird Connection"). These citations show how much work it takes to find evidence of the dinosaur and bird relationship. While not remaining on topic, the author also gives us insufficient evidence because it does not give us enough evidence to go by. The authors use personal, expert, and example as the classification triangle. There were many gaps and fallacious reasoning in the text including, how long it took to find out the truth, what steps they took, and also timelines. In order to make this text more accurate, we need graphs, pictures, and …show more content…

It shows that the behavior of brooding the nests that we see all around us today in living birds was already present in the non-bird ancestors of birds." Humans sometimes gather their behavior genes from their family, dinosaurs and birds can as well. Consequently, "The discovery of more and more non-flying dinosaurs with feathers dis- proved that explanation. For these dinosaurs, feathers may have served other functions, including gliding, insulation, protection, and display. Feathers play that same role in many bird species today." ("Shedding Light on the Dinosaur-Bird Connection"). These quotations demonstrate how behavior can show the different similarity traits. While remaining on topic, the authors implement examples, expertise, and detail to show the variety of evidence. The evidence given is sufficient, but there were many gaps made. The gaps and flaws listed point out their similarities on a graph. The authors should have provided the source of their information. What do birds really originate from? Dinosaurs and birds have relationships, they have evidence to prove it, and they have behavioral
