The woolly mammoth was a prehistoric animal that resembled an elephant and lived during the Ice Age. Some versions of the species are known to have survived until 6000 BCE, although most became extinct around 12000 BCE. Its extinction is best explained by a combination of climate change and over hunting by predators.
The woolly mammoth was well-adapted to the frigid, icy climate of the Ice Age, but as the period of cold concluded and the planet started to become warmer, the environment became unfriendly to woolly mammoths. The hair that kept them insulated against icy weather was approximately fifty centimeters long. Once the climate became warmer, however, this adaptation undoubtedly created serious problems for these animals and caused their populations to dwindle considerably.
Furthermore, during this climate change, predators like the saber-toothed tiger continued to hunt the mammoth. Saber-toothed tigers were roughly the size of lions and had twenty-centimeter-long teeth, allowing them to pierce through the fat of woolly mammoths effortlessly. Saber-toothed tigers also hunted in packs, offering them an important hunting advantage over the woolly mammoths. It is likely that saber-toothed tigers had a significant role in the woolly mammoth's extinction.
Finally, the woolly mammoth was a desirable animal to hunt for many wandering human tribes. Nearly all parts of woolly mammoths could be used by humans, making it a popular target for tribes-the mammoth's thick skin provided insulation against the cold, its bones could be used to create tools and the meat provided necessary protein and calories. Because woolly mammoths were so desirable, humans probably concentrated the majority of their hunting efforts on woolly mammoths alone, which dramatically diminished woolly mammoth populations and eventually led to their extinction.
According to the article, the wooly mammoth, which height near an elephant and lived during the Ice Age, became completely extinct about 6000 BCE. In this regard, the author stats tow effective reason for this extinction: the climate change and overhunting. On the contrary, the lecturer finds that arguments mentioned by the author hard to believe. I will explain the arguments stated by the author and the lecturer below.
First, it is stated in the reading that, because the climate changed into a warmer temperature and the woolly mammoth get used to living in cold temperatures so they cannot adapt to the new climate and extinct. However, the lecture questions this argument and mentioned that they could migrate into northern territories that were colder in order to cope with climate change. Therefore, this cannot be a good reason for their extinction.
Next, the reading puts forward to the idea that saber-toothed tiger, which has long teeth, during the climate change starts to hunt woolly mammoths. It was so large that had a significant role in extinction. In contrast, the lecturer refutes the role of the saber-toothed tiger. She believes that there is not sufficient evidence that proves that type of tiger was able to overhunt the woolly mammoth. It also had had a thick skin that probably that tiger cannot overcome it owning to its size.
Finally, the passage goes on to mention that humans overhunted the woolly mammoth in order to use its organs such as thick skin or its bones in various situations. While the lecture disputes this idea mentioning that there were other species like the buffaloes that humans could hunt them easier than the woolly mammoth in order to achieve those types of tools which they made by the woolly mammoth organs. So it is very problematic to accept overhunting by humans as a reason for the woolly mammoth extinction.
