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,
Stephen Gould’s essay “Sex, Drugs, Disasters, and the Extinction of the Dinosaurs” completely agrees with Joseph Williams and Gregory Colomb’s essay “Argument, Critical Thinking, and Rationality.” Gould’s essay deals with three theories for the extinction of the dinosaurs, two of which he argues are entirely invalid because they are not in accordance with the basic rules of argument laid out by Williams and Colomb in their essay. Gould also states that the third theory of dinosaur extinction, natural disaster, follows all the rules that Williams and Colomb espouse, and thus is a sound argument. Gould, Williams, and Colomb all state that the world has a problem with irrational arguments being shoved down people’s throats, and call for a
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.
It is said that there has been rare and precious Dinosaur bones discovered in the Eromanga sea, this almost proves that Dinosaurs once roamed around the shores. Also many of the significant events in Geological history, over the past 600 million years can be observed at Hallett Cove. Some of the oldest rocks have been found in these seas. The finding of the Ediacaran could potentially mean that there can be dinosaur fossils found in the ocean, or even that relatives of the ediacaran could be considered fossils and could be found in the sea.
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 the two essays being discussed we learn that science has a vast range of definitions. Science is the effort to understand (or to understand better), the history of the natural world and how the natural world works with observable physical evidence as the base of understanding. Science is about how the hypothesis is developed and how well it is defended.
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.
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 were over 1,000 different species of dinosaurs (“Dinosaurs”) that lived and evolved for almost 185 million years (“Dinosaur Facts”). Dinosaurs were some of the largest and most mysterious creatures to walk the Earth. Dinosaurs have helped scientists to understand the Earth and it 's past by studying different types, how they lived, their characteristics and what caused their mass extinction.
The author of the passage aims to provide information about the extinction of the dinosaurs. So there was one man called Alvarez, and he got a nobel prize about the extinction of the dinosaurs.
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
However, such mass extinction opens up speciation – when new species are developed. After the K-Pg extinction, new groups of organisms were on the rise. Giant boid snakes (12 – 15 meters) began appearing on land and the teleost fish (diverse class of ray-finned fish) filled marine niches left vacant. Most significantly, “Paleocene mammals would spread and evolve into the many ecological niches left open by the extinction of the dinosaurs,” (“Cretaceous: Extinction of the Dinosaurs”).
Nobody can really say what actually eliminated the species, although everyone has their very own idea. Asteroid impact, atmospheric changes (hot to cold), catastrophic eruptions and astronomical events (supernovas etc.). Some have ventured that early mammal inhabitation slowly “pushed” the dinosaurs to extinction. The most favored theory in the scientific field is that of the meteor impact. As always though, knowing when is part of discovering how and why.
