Woolly Mammoths: Article Analysis

The idea of using genetics to bring forth extinct animals is thrilling. Scientists and civilians alike consider all the insight and information we will discover once we construct animals that lived thousands of years before modern times. Unfortunately, there is a problem. With the CRISPR technology we can only edit genes, not change them completely. A prime example of this is the wooly mammoth. According to Lila Shapiro, the author of We May Resurrect the Mammoth Sooner Than You Think, she stated that CRIPR would recreate a hybrid, not a genetically correct mammoth. In Shapiro’s article, Dr. George Church is the leading scientist in de-extinction. His works is primary evolve around woolly mammoth. To bring them back from extinction, George

Imagine it’s 30 years in the future, you and your little grandchildren are going to the zoo to see the new and improved Wooly Mammoth. Except it’s not improved, it’s not even a purebred Wooly Mammoth, and its stuck in a cage. Scientist are trying to decide if they should resurrect the Wooly Mammoth, by breeding its embryo with an Asian Elephant. The Wooly Mammoth shouldn't be resurrected because, there is no habitat for them, costs, and is it even logically possible.

In 1813 a man by the name of John James Audubon witnessed a beautiful sight. Pigeons filled the skies of Ohio. Men and boys would shoot at the pigeons and the number decreased significantly. In 2003, Spanish and French scientists were focused on a wild goat named the bucardo. When the last bucardo died they tried to clone it, but it died after birth. Scientists have been trying to brink extinct animals back by using the preserved DNA. The most famous attempt is to bring back the Wolly Mammoth by using the preserved DNA found in chunks in Siberia. The use the Mammoth’s DNA and mix it with that of an elephant, the mammoth’s most closest living

Yes, I do believe that mammoths can really be brought back from extinction. Bringing these mammoths back to life is still a process. A scientist named George Church, along with his colleagues are using a process called de-extinction to achieve this very goal. A pro of this is because we get to study animal life and see how our ancestors work with mammoths. Also, in the process of trying to bring the mammoth back to life; we can learn a lot more about how de-extinction really works. On the other hand, there is a con. I feel as though adding another animal into the ecosystem comes in between the balance of things. Mammoths are extinct for a reason, bringing them back will only shorten other animals resources to survive. In the past it has been

According to Lister, the author of Mammoths: Ice age giants, woolly mammoths have been found frozen with different stages of digestion occurring in their stomachs, allowing their diet to be easily determined. They survived off of plants such as, grass and sedges, accompanied by, flowering plants, shrubs, mosses, and tree bark. Isotope analysis did prove that woolly mammoths ate mostly C3 plants. However, their diet did vary slightly by the location of their habitat. Woolly mammoths ate a wide-range diet to obtain their needed nutrition. Therefore, their molars were adapted to grind course grasses; the sharp enamel ridges ground the food by sliding across each other, and were wear-resistant to allow large quantities of food to be chewed. Also,

Not all of the mammoths went extinct in the same range of time, the extinction was a lot more spread out and based on the different circumstances each group of the mammoths were in.

The most rare method to find fossils is to find original skeleton material. some insects have been found in amber. The amber gives some scientists the chance to examine the skin, hair, and organs of prehistoric beings. The rarest form of fossilization is the preservation of original skeletal material and even soft tissue. For example, some insects have been preserved perfectly in amber, which is ancient tree sap. In addition, several mammoths and even a Neanderthal hunter have been discovered frozen in glaciers. The rarest form of fossilization is the preservation of original skeletal material and even soft tissue. For example, some insects have been preserved perfectly in amber, which is ancient tree sap. In addition, several mammoths and

As humans we are constantly intrigued by the idea of bring species that have been long extinct back to life in order study them and gain more knowledge about them. It has been estimated that about 99% of the four billion species on earth are extinct. Scientists and researcher gather what information that they can from the resources available, but there is so much more that we do not know, and are yet to find out. And with advances in cloning and genetic, that thought is not very far from becoming a reality.

“Our species has played a role in the extinction of these and many other species. But now some scientists are proposing a radical turn of the tables: Bringing lost species back from the dead” (Switek). Brian Switek, an author, says this in his article, How to Resurrect Lost Species because he thinks that this proposal will be difficult and extreme and that bringing extinct animals back will be a long process and may have some consequences behind it. Some scientist say that bringing back extinct animals will improve the environment and society because people will know what cloning technology is capable of and these animals may help environmental surroundings. Others say that it will be an irresponsible decision because it is a waste of money,

Recently, he and a team of colleagues confronted a new question: If molecular biologists can potentially reconstruct extinct species, such as the woolly mammoth, should society devote its limited resources to reversing past wrongs, or on preventing future extinctions? "If you have the millions of dollars it would take to resurrect a species and choose to do that, you are making an ethical decision to bring one species back and let several others go extinct," Dr.

Scientists estimate that 150-200 species of plants, insects, birds and mammals become extinct each day. Although the idea of bringing extinct or endangered animals back to it’s original population may be quite promising, animals that are used for this research may include those who are in poor living conditions. Plus,

The woolly mammoth or Mammuthus primigenius was one of the last species of mammoth to be alive during the Pleistocene epoch. Approximately 400,000 years ago in East Asia, the elephant like animal separated from the steppe mammoth. The Asian elephant is the closest relative to the woolly mammoth who still exists today. The difference between the two relatives are that woolly mammoths have a thick layer of brown fur to keep their bodies warm in the Arctic’s rough weather. The species had massive curved tusks that were used for self defense on predators and also digging for meals under the snow. Unfortunately, these species became extinct about 10,000 years ago. There are a few reasons why woolly mammoths became extinct and the research will prove that.

The article begins with a brief introduction as to what de-extinction projects consist of, saying that, “[“De-extinction”] projects propose to re-create or “resurrect” extinct species” (Page 131). It is later stated that “Such “de-extinction” projects are complicated, costly, and tremendously difficult. The author also raises a host of challenging philosophical and ethical questions, the most basic of which is whether or not they ought to be pursued at all. The thylacine, or better known as the Tasmanian tiger, is introduced with a story about their extinction, and how they became extinct. Most believed that they would stay extinct forever, but a genome replication created a ‘replica’ of the extinct species, which made people question if extinction truly is forever.

All that is known at this moment is what current literature work say in relation to the approximately 16000 endangered species (Panda, 2013). However, I do not intend to focus on such a large number of animals. Therefore, I will narrow down my investigation to focus on blue whale, polar bear, tiger and the mountain gorilla. Despite the fact that these animals are few, their number is significantly reducing and something needs to be done in order to save them. Another issue that I wish to investigate if the extermination of these five species of animals is likely to affect our very existence as humans.

There are presently over 8000 specimens of tissue samples in the San Diego frozen zoo in California. This come from 800 species or sub species and this is just a tip of the ice burg a million. Other such tissue banks are being put up around the world so that “they can be revived if necessary" (Lepage 2). This saving of human tissue should not be the answer to the problem of possible extinction of the various animals in the world. It is upon human beings to find ways to reduce their impact on animal life so as to safeguard instead of threaten the animals with extinction and then look to revive this animal life. It is much simpler for humans to change their ways such as stopping the rapid deforestation and encroaching in animal habitats and using of fossil fuels and polluting of the rivers with refuse from excesses of consumerism than it is to try and reintroduce this species when they go extinct because even the chances of man mimicking millions of years of creation are very slim at best. In South Africa in the Cape region they have seen that it is important to facilitate evolution instead of try to put it in a bottle. Dr. Richard Cowling of the Nelson Mandela Metropolitan University, Port Elizabeth says that ""You 've got to preserve the processes."(Le Page, 2) Scientists have tried to invent
