Extinction is one of the first scientific concepts that children learn about; when small children play with toy dinosaurs they learn that the dinosaurs died a long time ago.
Strange as it sounds, a small child living in the 21st century has a better grasp of the history of life on Earth than scientists did thousands of years ago. Aristotlefor instance, wrote a long treatise on animals without considering the possibility that some animals went extinct.
Though the concept of extinction is relatively uncontroversial today even children know about itscientists only realized that animals go extinct very recently. Kolbert will study the process by which scientists introduce a new idea for example, the idea that animals go extinct —usually, the idea is dismissed and ridiculed at first, but eventually becomes an accepted fact.
Active Themes. Mass-extinction and Morality. Scientists first proposed the concept of extinction in the late 18th century. A naturalist named Georges Cuvier studied the fossils of an animal now known as the American mastodon, or Mammut americanumand concluded that all such creatures must have died out in the distant past. Cuvier introduced the then-revolutionary idea that animals go extinct.
Natural Selection and Mass-extinction. Related Quotes with Explanations. European explorers probably discovered mastodon teeth in the early 18th century; then, inCharles le Moyne, the Baron de Longueuildiscovered mastodon bones while exploring present-day Ohio.
Louis kept the mastodon bones in his museum. One of the most important stages in scientific theory is gathering evidence. For most of the 18th century, French scientists debated the origins of the mastodon remains. Some argued that the bones actually belonged to the sixth extinction elizabeth kolbert pdf download or three creatures, including a hippopotamus. Even Thomas Jeffersona naturalist as well as a statesman, wrote a paper in which he argued that the remains must belong to an existent, undiscovered animal, probably the largest animal alive.
Jefferson hoped to track down the sixth extinction elizabeth kolbert pdf download mysterious animal somewhere in the American continent. The mounting evidence of fossil records showed that some animals died out a long time ago. However, before Cuvier and even afterwards, for a timescientists and naturalists were convinced that the fossils belonged to species that were still in existence.
This shows a moment when the dominant paradigm was fracturing based on evidence, clearing the way for a new theory. Cuvier lived in Paris at the end of the 18th century, and worked as a lecturer for the Paris Museum of Natural History. On April 4,Cuvier delivered a revolutionary lecture the sixth extinction elizabeth kolbert pdf download which he discussed the Mastodon remains from Ohio, as well as the remains the sixth extinction elizabeth kolbert pdf download a similar creature that had been discovered in Russia.
Cuvier proposed that the two sets of remains belonged to huge, elephantine creatures—two new animal species, neither one of which had survived. Finding evidence of other lost creatures among those remains, Cuvier concluded that they must have belonged to vanished species. He extrapolated these findings to conclude that there must be a huge number of species that died out over time, the sixth extinction elizabeth kolbert pdf download.
Cuvier did not, however, understand what could have led these lost species to die out. First, notice that Cuvier based his findings on his analysis of all available evidence—the fossils from Ohio, Russia, and other places. Mastodon teeth are huge and brownish, but they have the same basic structure as human teeth; dentin, surrounded by brittle enamel. Many of the fossils that Cuvier examined hundreds of years ago are still located in the same place—the Paris Museum of Natural History.
Furthermore, notice that, in those hundreds of years, Cuvier has gone from a controversial, revolutionary figure to a celebrated scientific hero.
However, Cuvier needed to find more fossils to bolster his claim that the Earth was once full of now-extinct species. Cuvier investigated the quarries surrounding Paris, eventually identifying twenty-three new species that he believed to be extinct. Even after he developed his theory of extinction, the sixth extinction elizabeth kolbert pdf download, Cuvier continued to move the scientific discourse forward.
First, he continued to travel around the world, searching for more extinct species that could prove his controversial theory. But second, and perhaps more importantly, Cuvier made an effort to popularize his theory for the general public—a crucial part of the process by which a scientific theory becomes accepted. The theory of extinction was particularly popular in the early United States, owing partly to the influence of Thomas Jefferson. Kolbert studies the way that extinction theory was received in the United States.
Notice, the sixth extinction elizabeth kolbert pdf download, that the lasting confusion between mammoths and mastodons which are two different animals reflects the difficulty of popularizing technical and complex scientific theories. Toward the end of his life Cuvier became a hero throughout Europe and the U. One fossil hunter discovered the remains of a huge, lizard-like creature, the ichthyosaur.
Slowly, the sixth extinction elizabeth kolbert pdf download, scientists began to notice a pattern with fossils—the older the fossil, the deeper in the earth it was likely buried fossils discovered near the surface likely belonged to non-extinct animals. Even though Cuvier had been a controversial figure as a younger man, he died a popular, respected scientist.
This goes to show that paradigms fracture and evolve gradually—important leaps forward in knowledge can be accompanied by the remains of outdated and false ideas. Even when his ideas were wrong, Cuvier was using the scientific method to advance them. Science, in other words, is a human process that is not infallible. Cuvier had determined that some species went extinct over time.
But the sixth extinction elizabeth kolbert pdf download still needed an explanation for why this happened. At first, he proposed that one great disaster in the distant past had wiped out species simultaneously. Inthe sixth extinction elizabeth kolbert pdf download, Cuvier wrote an influential essay about the possibility of ancient, cataclysmic events. Although Cuvier made a point to cite multiple religious texts in his essay, the predominately Anglican staff of Oxford and Cambridge ensured that, when the essay was translated into English, it favored a Christian interpretation.
However, his basic idea that species go extinct over time paved the way for future research. Interestingly, Cuvier pointed out that the American mastodon went extinct about 13, years ago, which is correct. However, though he thought this was due to floods or other large natural disasters, the mastodon probably went extinct because human beings hunted it to extinction. Cite This Page.
