Similarities Between Birds And Dinosaurs

Register to read the introduction… There is very strong evidence to suggest that dinosaurs evolved into birds, but yet again there are many doubters of this theory. A very noticeable physical feature on both birds and some prehistoric dinosaurs is that they both have three toes on their foot going forward and one toe going back. This is an unusual feature that draws immediate attention to their physical similarities. Another likeness between birds and some dinosaurs is that each has a claw coming off of each one of their toes. Also, it cannot be overlooked that both birds and dinosaurs also have a wishbone right between their shoulder blades. This skeletal similarity is unusual and strongly supports a relationship between the species. Yet another noteworthy comparison between birds and dinosaurs is their very comparable bone structure. If one looked at the bone structure of their necks, one would notice that they both of their necks are very thin and are curved like an “s”. This further suggests a physical commonality between the species. One of the more compelling reasons to believe that this theory is true is that when examining the brain of a tyrannosaurus rex, it has very large olfactory lobes, which indicates that it had a very good sense of smell. Some birds, including turkey vultures, kiwi birds, and tubed nose sea birds, also have large olfactory lobes and a very good sense of smell. For all those reasons it makes good scientific sense to question the physical relationship that exists between birds and dinosaurs. If one accepts Darwin’s Theory of Evolution then it is reasonable to question whether or not dinosaurs ever truly went extinct. Instead it could be possible that dinosaurs evolved over time into birds. Instead of seeing dinosaurs as a separate species which went extinct, one might think of dinosaurs as the genetic ancestors to birds. Considering all of the physical similarities that …show more content…
For example, scientists have clearly observed that some insects have evolved over time in order to adapt to their environment, therefore increasing their chances of survival. For instance, when an insecticide is released into an insect population within a home, as soon as the poison reaches the bugs, most will die. The select few that survive the insecticide have shown a remarkable ability to genetically change in order to better protect itself against the insecticide meant to kill it. This lucky group of insects will continue to reproduce offspring and then their offspring’s offspring will reproduce more offspring and the cycle will continue with each generation better able to defend itself against the insecticide. Eventually there will be a greater percentage of the insects that are immune to the insecticide then there will be of insects that will die from the insecticide. This demonstrates Darwin’s Theory of Natural Selection, in which an organism that is better adapted to a certain environment will live longer and reproduce better and have healthier offspring than an organism which fails to adapt to its environment. Along the same line of reasoning, many people are interested in selective breeding. This is basically a form of evolution that humans create. By definition, selective breeding is when man chooses certain organisms to mate in order to produce off spring that will have desirable traits. This most commonly happens when humans choose two dog breeds to mate so that their puppies have attractive traits. When this happens hybrid breeds are formed such as the golden doodle, which is the puppy of a golden retriever and a poodle, and over time and after several generations of mixed breeding the new breed will be formally
