The Pleistocene epoch spanned from 1.8 million years ago to 10,000 years ago [1]. Many genera and even species such as conifers, mosses, flowering plants, insects, mollusks, birds, and mammals from that era still survive today [1]. Others, such as the long-horned bison, saber-toothed cats, giant ground sloths, and the mammoth did not survive [1].
The woolly mammoth was commonly found during the last ice age [2]. These animals were similar in size to today’s elephants but were adapted for living in the extremely cold conditions typical of an ice age [2]. Mammoths had narrower skulls, shorter tails, and smaller ears than elephants do, and they were protected by a full coat of coarse hair that secreted oils and insulated them from the cold [2]. The mammoths also had tusks that they used to clear away snow in their search for food [2].
Mammoths went extinct approximately 4,000 years ago after their numbers began to diminish about 10,000 years ago [2]. Mammoth fossils have been uncovered on every continent except for South America and Australia [2]. It is not entirely clear what led to the extinction of the mammoth [2]. Some of the current theories for their extinction include climate change, meteorites or comets, and predation by humans [2].
The most recognized reason for the mammoth’s disappearance is that as the Earth warmed, the climate became too much for the mammoths to handle since they had evolved in a cold environment [2]. It is also possible that the global climate change led to the extinction of some of the mammoth’s vital mineral-supplying plants which in turn led to the extinction of the mammoth [2].
Researchers have also found some evidence of an asteroid hitting the Earth which may have resulted in a massive climate ch...

...ts and more species will begin to go extinct [13].
Other researchers believe that bringing back the mammoth and other extinct species will increase conservation efforts [4]. They argue that by creating more species that are in need of a home, people will be driven to preserve land where they can survive [4]. In fact, a nature preserve covering a sixty-square-mile area has already been established in Siberia in the hopes that it will one day soon be inhabited by mammoths [4].
While society may not currently be ready for the revival of creatures that went extinct thousands of years ago, technology certainly has that goal in its sights. Since cloning and genome sequencing techniques are still in need of refinement, it will give naysayers time to come to terms with researchers aspirations. After all, it seems that sooner or later, mammoths will walk the Earth again.

Cloning is a Good Thing Essay - Imagine seeing dinosaurs or other extinct animals roaming the world. Instead of going to museums to see motionless statues of them, see them alive and living. While this may be a bizarre concept, scientists have found a way to clone and make animals by just having a single strand or data of DNA. For example, if they happen to find a strand of hair from a wooly mammoth, scientists can actually create the creature. Cloning should be legalized because it can be used for many propitious purposes, from medical research, to bringing back endangered species, to cloning embryonic stem cells for medical uses, to cloning animals that contain meat for food, and cloning human body parts for people in ca...   [tags: stem cells, rhetorical] 587 words

Cloning Essay - It all started back in the fifties when James Watson and Francis Crick discovered the structure of DNA (D’Souza NA). Ever since there has been talk of human and animal cloning. It all seemed out of reach and basically impossible, but in 1997 that all changed when a sheep, named Dolly, was the first ever mammal to be cloned. She was cloned for the purpose of curing disease and research on animal organs for human transplantation (Schaeffer 3). Now that scientists know that it is possible to clone literally anything with DNA, the world has become a rather scary place....   [tags: DNA ]

The Benefits of Cloning Essay - The Benefits of Cloning Imagine having a twin that looks and acts exactly like you. Even more interesting this twin is a product of scientific cloning. If scientists have their way, identical replicas of human beings will be roaming the earth. This scientific vision may occur a lot more recent then many think. Cloning can be (better) understood by looking at it’s definition, process, and some examples. This first step to better understanding cloning is to hear precisely what it is. Cloning can be defined as an organism or group of organisms derived from another organism by an asexual reproductive process....   [tags: essays research papers fc]

Essay on A Case for Cloning - One reason people protest the idea of cloning is because may are mystified as to how it could be used and what its purposes can be. I know that if it were your child, you would use every possible measure to keep them alive. The fact that we, as humans, might be able to figure out how to clone so that lives could be saved is extremely exciting and inspiring. On the other hand, there is a time and a place for everything, including research. While cloning is justifiable in certain circumstances, I would want to make sure other healthcare issues were taken care before donating money to research for cloning....   [tags: Cloning] 1446 words

Essay on History of Cloning - Cloning is defined as the different processes for duplicating biological materials such as tissues and new life forms (“Cloning Fact Sheet” 2009). The cloning of human tissue should be allowed because the fields of medicine benefit from it; however, the full cloning of humans is a mockery of life because it creates a population of people who will not evolve or adapt to changes in the environment. Therefore, the government should financially support the research of therapeutic cloning while condemning the act of reproductive human cloning....   [tags: Cloning]

Essay about Cloning - For the last few decades, cloning was a fictitious idea that lay deep within the pages of some sci-fi novels. The very idea that cloning could one day become reality was thought to be a scientific impossibility by many experts but on one exhilarating day, what was thought to be "purely fiction" became reality. That fine day was February 22, 1997. A team from the Roslin Institute which was lead by Dr. Ian Wilmut changed the face of history forever by revealing what looked like an average sheep. That sheep was what was going to be one of the most famous if not the most famous sheep in modern day....   [tags: Biology Cloning] 937 words
