The extinction of dinosaurs can be seen as a lot of speculation. In “Sex, Drugs, Disasters, and the Extinction of Dinosaurs” Stephen Jay Gould explains how “science, is a fruitful mode of inquiry, not a list of enticing conclusions.” (Gould, 216). What makes something speculation and not science, which of the three theories are speculation, and what makes Gould question the theories. In “Sex, Drugs, Disasters, and the Extinction of Dinosaurs” Gould explains the differences of science and speculation

Dinosaur extinction is still a major mystery of earth history. In this review article, extinctions in the geological record will be briefly mentioned. Many of the imaginative theories for the extinction of the dinosaurs will also be presented. Within the uniformitarian paradigm, the meteorite impact theory, once considered ‘outrageous’, now is the dominant theory. However, the volcanic theory is still believed by a majority of paleontologists. Both theories have their strengths and weaknesses. The

the extinction of the dinosaurs. According to one theory, dinosaurs were slowly driven to extinction by environmental changes linked to the creeping withdrawal of shallow seas from the continents at the end of the dinosaur era. Proponents of this theory propose that dinosaurs dwindled in number and variety over several million years. An opposing theory proposes that the impact of asteroid or comet caused catastrophic destruction of the environment, leading to the extinction of the dinosaurs. Evidence

primary discussion for a very long time, but what exactly is evolution? Naturally, there are two theories. One religious, and the other scientific. The religious theory states that god is the creator of all living things, but on the other hand, the scientific theory states that the ‘Big Bang’, an explosion, is the base for living things. I decided to write about the evolution and extinction of dinosaurs because the whole idea of a species so majestic, large and powerful getting completely wiped out

Extinction . As Dead as a Dodo! For every species that is alive today, perhaps a thousand more have lived previously and become extinct. Most of these extinctions occurred before humans evolved, and the species are known to us only through fossils The Dodo The dodo was a large (50 lb) flightless bird that lived on Mauritius, an island in the Indian Ocean. It lived undisturbed for so long that it lost its need and ability to fly. It lived and nested on the ground and ate fruits that had fallen

the force an asteroid can have when impacting firsthand. There is evidence of asteroid impacts covering the surface of the earth and other surrounding planets in space. There are also many theories involving asteroid impacts causing mass extinctions on Earth, the most common being the extinction of the dinosaurs 65 million years ago (deGrasse Tyson, 2005). Most of the impact evidence shows that the earth has been attacked by these asteroids since its formation billions of years ago. Evidence all around

of the greatest scientific mystery has involved the comet that caused extinction of dinosaurs and mass destruction to food chain that has existed. Although the modern world has advanced significantly in technology and science, there is still much more mystery to be discovered about the early earth and the events that took place for the extinction of many species. Many scientists have created multiple theories on how the dinosaurs and other species went extinct. Walter Alvarez, a Berkeley scientist

Review the theories put forward in the literature that attempt to explain why there was a mass extinction at the end of the Cretaceous period. You should aim to outline the main theories, the claims they make, briefly explain any supporting evidence, and compare and contrast the rival theories. Reasons for the Cretaceous mass extinction have been hotly debated for more than 200 years, since the founding days of geology. Cretaceous mass extinction is referred to the mass extinction that happened

the Mesozoic towering dinosaurs and extended hominid human family. The unique fossils, concrete interactive displays and recreated sea and terrestrial landscapes help the compelling story of evolution- the single process that connects everything that has ever lived on earth. Evolution of life on Earth occurred 4.5 billion years ago, the Precambrian Eon. This Eon makes up ninety percent of Earth’s history. Organic compounds were the building blocks on Earth; two theories exist of how these forms
