Dinosaurs Persuasive Essay

A dinosaur has an antorbital fenestra with an open hole hip socket. The definition differs from the term used informally because it helped understand how the dinosaur moved and how they were categorized as species. There are four general characteristics that dinosaurs have as a result of their synapomorphies which are permeated acetabulum, ball-shaped head on proximal femur, the Cnemial crest on the proximial tibia, and an ascending process on astragalus. These four dinosaur synapomorphies are related to vertical limb support.

So what killed the dinosaurs? Without having any background education in science it is hard for the general public to comprehend such matters and they rely on the knowledge of the scientists in this field. Although there has been much research on the subject nobody has come up with a conclusive answer. And we are left to read the countless articles, all having their own opinions as to the mass extinction. One such theory is that a shift in the solar system could have caused the mass destruction. According to an article published in Nature magazine,

Nobody knows for sure exactly how the dinosaurs became extinct. However scientists have speculated for decades about possible events that caused the dinosaurs to die out. Possibilities range from asteroids, to volcanoes, to climate changes. One of the more popular or well-known extinction theories involves the belief that an asteroid struck the Earth, causing devastating effects, and triggering mass extinctions around the end of the Cretaceous period.

In 1993, Steven Spielburg’s Jurassic Park introduced the concept of bringing extinct species back. In 2003, a team of Spanish and French scientists took Spielburg’s movie to the next level—they successfully brought back the Pyrenean ibex, a species of wild goat (93). With increasing rates of extinction, the scientific community is debating whether or not this process of de-extinction should continue to be pursued. Although it would be remarkable to visit an exhibit featuring a saber-tooth tiger or woolly mammoth, these animals went extinct for a reason; humans should not bring back extinct animals, but instead use the funding for more practical purposes.

Dinosaurs ruled the earth for over 65 million years and thankfully for the human race, they became extinct. Ultimately, only a major catastrophe could completely wipe out an entire species, let alone an entity of dinosaurs and the debacle on the causes of dinosaur extinction have flooded the minds of paleontologists for centuries. Geologist and zoologist Stephen Jay Gould published “Sex, Drugs, Disasters, and the Extinction of Dinosaurs,” to compare scientific and speculative causes of dinosaur decimation. Personally, I found this passage very informational and enjoyed reading it. Gould provides three theories that capture the reader’s curiosity, allowing room for pondering in one’s mind.

In Stephen Jay Gould’s “Sex, Drugs, Disasters, and the Extinction of Dinosaurs”, Gould investigates three possible theories hypothesizing the reason behind the extinction of dinosaurs. The first theory suggests that dinosaurs became extinct due to a rise in temperature, which caused sperm to die, leading to the sterilization of male dinosaurs. The second hypothesis offer that many dinosaurs consumed bitter plants that contained psychoactive agents which their lives could not detoxify out of their systems. The last speculation about the dinosaur’s extinction is that a large cloud of dust formed in the atmosphere after an asteroid hit Earth’s surface. This dust cloud blocked out the sunlight, causing temperatures to drop and made photosynthesis impossible. Gould uses these three theories to lead to his central claim that science isn’t just about making fascinating claims, but should have a well developed hypothesis.

Jurassic Park is a science fiction novel written by Michael Crichton which was published in 1990. The book follows a mysterious island that is inhabited by genetically engineered dinosaurs created by a bioengineering firm. The story lets us watch as visitors land on the island at the request of the rich billionaire who owns the island and the bioengineering firm, which is named InGen to revel in the wonder that they have created. We follow all the miss-steps until all is lost and the island has to be destroyed. The novel is one to give us insight into what can happen when we try to play god and foreshadows what possibly could go wrong by taking that next step into genetics that could be considered reckless and dangerous. Crichton lets us

Because dinosaurs are animals that lived millions of years ago, we are entirely dependent on the fossils that they have left behind for any understanding that we hope to gain. As any paleontologist will tell you, fossil hunting is difficult. There are no certainties, no guarantees. A certain amount of luck is as valuable as any scientific knowledge.

Imagine it’s 30 years in the future, you and your little grandchildren are going to the zoo to see the new and improved Wooly Mammoth. Except it’s not improved, it’s not even a purebred Wooly Mammoth, and its stuck in a cage. Scientist are trying to decide if they should resurrect the Wooly Mammoth, by breeding its embryo with an Asian Elephant. The Wooly Mammoth shouldn't be resurrected because, there is no habitat for them, costs, and is it even logically possible.

The story of Jurassic Park was written about fourteen years ago by a man named Michael Crichton. His book has now evolved into three movies of Jurassic Park I, II, and III. Steven Speilberg has taken the story of Crichton is transformed it into one of his action packed, suspense thrillers.

There are a lot of movies made about our world and what our world could be. They show

            At a time, scientists believed all dinosaurs were cold-blooded.  However, with a recent discovery of a dinosaur found with a fossilized heart in the northern part of South Dakota in 1993, many paleontologists are starting to think that there were some dinosaurs that were warm blooded.

The author is Michael Crichton, and the book is The Lost World. Many people have read this book, along with its predecessor, Jurassic Park, and many people have been enthralled with the thought of living dinosaurs in the 20th century. “What if the dinosaurs did not become extinct? What if they still exist?” (The Lost World takes off a couple years after the first book. A separate island is discovered, an island where the dinosaurs were actually created. There are two different research groups sent to the island. One to observe the dinosaurs in the wild and the other to bring them back for research purposes. The fighting starts from there. What many people don’t know, is that these books, along with countless other

Dinosaur extinction: An analysis of events and theories that possibly led to the dinosaurs' demise.

With nearly millions of animals dying each year from being captive, or endangered species being hunted down and killed, we need to discover a new way of displaying that our world is full of beautiful animals and wildlife. Wild animals are suffering both physically and mentally from the lack of freedom that confinement imposes. These harmful environments are preventing animals from having the opportunity to live in, and be exposed to their natural habitats. Keeping animals imprisoned in cages and small enclosures just for the sake of human observation causes stress and frustration, which is risking animals overall health and well being. These morally unacceptable and cruel actions of retaining wild animals in captivity is certainly wrong.
