What Is Tardigrade Possible Extinction?

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

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.

My trip to the La Brea Tar Pits, taught me of the biodiversity that was within California, from the Columbian Mammoths, Shasta Ground Sloth, Dire Wolves, and Sabretooth Cats. The museum emphasized that most of the extinct animals that were on display were extinct due to climate change or hunted by the earliest tribes throughout California and North America. The museum points out that most of these animals were large, but doesn’t show the reason as to why the larger animals went extinct, but the smaller animals survived the extinction. The museum also mentions that night-stalking animals weren’t found in the pits as during the cool temperatures throughout the evening would solidify the asphalt. This extinction was known as the Pleistocene

De-extinction offers the possibility for extinct species to be brought back to life by reproductive cloning. Critics argue that de-extinction will reduce the will of society to protect endangered species, as well as harm the existing ecosystem upon species’ reintroduction. However, supporters argue that many species would be great candidates for de-extinction and will possibly be beneficial to the ecosystem. I will argue that de-extinction should not be pursued. I will argue that reintroduction of unextinct species could cause humanity to become disinterested in protecting endangered species due to the loss of finality of extinction. Furthermore, re-introduction of extinct species into ecosystems would negatively shift the balance, and may cause endangerment and potential extinction of otherwise unharmed populations.

The book I choose The Sixth Extinction, is by a woman who is a journalist for The New Yorker. So when I did my search, articles by her were the first that presented themselves. I have to admit, I cheated a little bit in that I used the first three news links that were not by her.

As a result, humans are slowly destroying the bear's ability to reproduce, and function in a normal way. By removing chemicals such as mercury, DDT, PCBs and lindane to name a few from our waste it is possible that the world may be able to retain our population of arctic polar bears, and preserve the beautiful creature for generations to come. Alternatively, people should use this as a warning of things to come if they continue to be so irresponsible about their waste. The implications to other ecosystems could be sufficiently more devastating than what is being witnessed in the arctic, and it is humanity's responsibility to take action now before it is too

Chapter 2: In chapter two of The Sixth Extinction the book explains how extinction is one of the first scientific concepts that children learn in school. Also, it talks about how children in the modern times know more about extinction than scientists did hundreds of years ago. Scientists first theorized the concept of extinction in the late 18th century. In this chapter the book also talked about how a naturalist named Georges Cuvier studied the fossils of an extinct animal called the American Mastodon, or Mammut Americanum, and decided that this creature, like many others, must have all died in the past. In his lifetime, many of Cuvier’s ideas about extinction were harshly criticized, but now, hundreds of years later, Cuvier is praised for

The Smilodon, commonly known as the Saber-toothed Tiger, was an intense carnivore in which was completely unrelated to today’s common Asian Tiger. Saber-toothed cats are predicted to have gone extinct towards the end of the Pleistocene era, 12,000 years ago. The exact cause of the extinction is unknown, however, scientists believe it to be due to the extinction of animals they preyed on, with the possibility of climate change. Smilodons lived in North and South America, generically in grasslands, shrubby areas, and pine forests that also supported the plant-eating lifestyle of animals that Saber-tooths so frequently preyed on. The fossils of this particular species was first discovered in 1842, in Brazil. Currently, the largest known collection

Sharks play a crucial role in the ecosystem. They are an apex predator and are critical to keeping balance and safety of their community and even their ecosystem. Due to overexploitation, many species of sharks are close to extinction and this can lead to devastating impacts in the ocean ecosystem. The shark keeps the food webs in balance. The keep the population of many prey under checked. For example since the population of sharks have dwindled down, the cow nose ray population blew out of proportion. Because of this the ray destroyed the population of one of their main source of food, the bay scallops. If it were not for sharks, many species would overpopulate and cause the same harm as the cow nose ray. While keeping prey from overpopulation,

During Late Pleistocene a megafaunal mass extinction took place. It’s still debated whether humans are to blame for this, since this megafaunal extinction happened after the arrival of humans or if climate change is entirely to blame. Fossil evidence has been of great help in finding what factors might’ve caused this extinction. This mass extinction that took place is related to the Anthropocene because if humans were the main cause, humans need to be more careful now because their actions may lead to more extinctions. The observations made were the types of species that went extinct with climate change, and what humans did to contribute to this mass extinction.

The Cretaceous-Tertiary extinction or K-T extinction, which marks the Late Cretaceous, is a massive and large-scale extinction of animal and plant species that occurred over a short period of time 66 million years ago.

Tardigens are usually the first living creatures on new lands, even though humans claim all the glories Tardigrades are actually the first to land on the new land even if its a harsh land. They can live in as cold as minus 328 degrees Fahrenheit or highs of more than 300 degrees F (148.9 C), according to Smithsonian magazine. Not even radiation, boiling liquids, massive amounts of pressure of us to six times the pressure of the deepest part of the ocean and even the vacuum of space without any protection can harm the (for a good 10 days at least). Even though tardigrades can live just about anywhere they prefer to live in moist environments such as lakes, moss,

During the Devonian period, most of the oceans were filled with stromatoporoids, brachiopods and corals. The Devonian period gave rises to some of the first tetrapods, amphibians, sharks, insects and boney fish. The first real land plants were also formed, giving rise to the first forest. The first plants were only about a foot tall and had no roots or leaves. By the late Devonian, plants had formed roots and leaves.

Tardigrades: the durable wonder of the animal kingdom. These nearly indestructible, microscopic organisms can be found just about anywhere in the world either in water or on moss and lichen plantation(1) Even though tardigrades prefer to live in a moist environment or on the surface of plants, they are not picky. Tardigrades are able to survive in the vacuum of space of space as well temperatures ranging from -200°C to 151°C.(2). There have been over 1,000 described species since this organism was discovered back in 1773 and there are more being discovered all the time.(3) The question is, are tardigrades living or nonliving?

Frogs and Koala bears are commonly known throughout the world. However, they are facing threatening consequences. The article states that, they are both losing their homes and are becoming extinct. Many people try to help with this problem.
