Stephen Jay Gould Sex Drugs Disasters And The Extinction Of Dinosaurs

Decent Essays
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. Defining science in his own words, Gould states…show more content…
At the beginning of the passage, he tells the readers that two of these theories are speculation and the other is pure science but each one is hard to dismiss. Testicular malfunction, the first example, cannot provide enough evidence to support this theory, solely because a paleontologist cannot extract samples and information from a fossil and simply because testicles do not fossilize. The scientists proving this theory, E. H. Colbert for an example, admitted that testicular malfunction is just a hypothesis. Therefore, Gould believes that this theory is merely unusable, but not as disadvantageous as psychoactive overdosing. Drug overdosing, like sex, can not be tested because again, like testicles, livers do not fossilize. In addition, there is also not enough evidence to prove this theory explicable, thus becoming another speculation proposal. Consequently, the theory of asteroidal zapping is the exponential scientific reasoning for dinosaur extinction. This theory can be proven by Luis and Walter Alvarez, a father-son geologist team, who became the first to propose the idea of asteroidal collision. The father and son duo collected sediment samples from deep in the Earth’s core in which they found extremely high amounts of iridium. Iridium is a highly testable chemical, therefore allowing the theory of asteroid and earth collision to be plausible. Gould’s final analysis proposes that asteroidal collision is the most scientific theory among the three. The author believes the asteroid colliding with earth and changing its temperatures allowed for evolution to happen. In summary, Gould distinctly and carefully analyzes the three theories, showing his reasoning for his scientific
