Sex, Drugs, Disasters, and the Extinction of Dinosaurs by Stephen Jay G

Sex, Drugs, Disasters, and the Extinction of Dinosaurs is written by Stephen Jay Gould, professor of geology and beast at Harvard. This essay is one of more(prenominal) than a hundred articles on evolution, zoology, and paleontology published by Gould in national magazines and journals. It tells about scientific proposals for the extinction of dinosaurs a confusing but an exciting problem that humans tries to solve. By analyzing and describing each of the claims for the reptiles demise sex, drugs, and misadventures Gould differentiates bad wisdom from good skill and excuses what makes some theories silly speculations, while the different, a testable hypothesis. Any hypothesis, Gould says, begins with the collection of facts. In this early stage of a conjecture development bad science leads nowhere, since it contains either little or contradicting evidence. On the other hand, Gould suggests, testable proposals are authorized temporarily, furthermore, new collected fa cts confirm a hypothesis. That is how good science works. It is self-correcting and self-developing with the flow of time new information improves a good theory and makes it more precise. Finally, good hypotheses create logical relations to other subjects and contribute to their expansion.The disaster theory, Gould claims, is an example of good science. It has testable evidence and has an impact on studies in other fields of science, it develops further and explains why the extinction of dinosaurs occurred simultaneously with other events. This theory suggests that a large comet hit the Earth sixty five one thousand million years ago, causing the cloud of dust to rise into the sky and to dodge sunlight. As a result, world temperatures went down significantly, the ice age bega... ...r best temperatures, hot climate caused the dinosaurs to heat up beyond their optimum. However, the heat didnt kill them, but sterilized the males, because their testes functioned at certain temperat ures. Gould argues that this theory is untestable, and the experiments with the mould of extreme temperatures on modern alligators do not necessarily explain the extinction of dinosaurs. Furthermore, many questions are not answered because of the absence of evidence. Gould states that this theory is other example of bad science.Sex, drugs, and disasters are both popular topics that grab usual attention and scientific theories of the extinction of dinosaurs. While sex and drug hypotheses plant silly speculations, the disaster claim is good science it provides testable evidence, has an impact on other scientific fields, and generates continuous research.
