Did Birds Really Derive From Dinosaurs?
The possibility that birds derived from dinosaurs has been under argument for years now. I personally believe that the two reptiles have too many similarities for them to not be related. Aside from their physical descriptions, dinosaurs and birds also use their clawed hands to obtain food. But these are only two vague examples, and not enough to support my theory. I plan on filling the next three paragraphs with information that will help you come to the same conclusion I’ve come to.
Starting with their teeth and expanding to their forelimbs, the common day bird resembles the now extinct dinosaur. They have flexible wrists, clawed hands, hollow bones, holes in their skulls, strap like shoulder blades, and many more features that the dinosaur once had.
I know what you’re thinking. How can an extinct animal be ancestor to a living creature? Well, I’m not saying that the two animals are closely related. In fact, this is where Darwin’s theory of evolution comes into play. Basically, animals evolve over time. Sometimes to better fit in with their environment, but most of the time there is no explanation. Think about how different we are from our ancestors, known as cavemen. Isn’t it essentially the same thing? Over billions of years things have changed, this includes animals.
As you can probably see, it’ll be a long time before anyone can really know for sure whether or not birds derived from dinosaurs. Although nothing is set in stone, I believe that birds, while probably not closely related, have derived from dinosaurs. And while I have no way of really being sure of anyone else’s opinion, I can only hope that after reading my article you can at least see my point and understand my reasoning.

dear Anna Louise,
ReplyDeletegreat job! Pointing the physical similarities of birds and dinosaurs was nice. Also, explaining Darwin's theory was really impressive. Well, I think if you write more evidences, it would be a better article. Anyway, well done AL!
