Skeletal. Behavioral. Behavioral. Behavioral. Behavioral. Brain. Initially these three claims in the text, "Shedding Light on the Dinosaur-Bird Connection," show how birds are so much more similar to dinosaurs than other animals. Initially, the first claim the authors make in the excerpt,"Shedding Light on the Dinosaur-Bird Connection" is the fact that the skeletal evidence of birds shows so much similarity to the dinosaur. As the authors remark,"[t]hey both have a hole in the hipbone, a feature that distinguishes most dinosaurs from all other animals." This evidence shows the similar features of the hipbone in both animals. Remaining on topic, the authors provide sufficient evidence by stipulating pictures of dinosaurs and birds. Additionally, …show more content…

However, these animals both built nests, laid eggs, and also brooded. As the authors state,"they see evidence of behaviors that are common to living birds, such as nest-building, egg-laying, and brooding." Therefore, these traits are very comparable. These traits show how equivalent these animals really are. Staying on topic, these two animals compare so much by the way the dinosaurs acted before going extinct and by the way the birds act nowadays. However, the authors include abundant amounts of evidence and pictures to show how the fossils, nesting, and brooding from both animals were so alike. Moreover, the two animals had other things in common, such as brain evidence. Finally, in the text,"Shedding Light on the Dinosaur-Bird Connection" the authors explain how similar the brains of these two animals are. However, the authors state,"In a recent study researchers were able to peer inside the brain cases of more than two dozen specimens, including birds and closely related non-bird dinosaurs." This evidence shows the machine they have is able to look at the brains of these two animals to know the possible
