Megafauna of Africa

For the past 700,000 years Earth’s climate has fluctuated with ice ages occurring about every 100,000 years with short warm spells or “interglacials” of about 10,000 years between them. Mammoths were able to migrate from Africa to around 6.7 million years ago and stay for about 4 million years before moving up into Southern Europe. But because the mammoth lived in the Arctic, many remains of the species have been found preserved in the permafrost. Mammoths survived in the climate until nearly 1650 BC before they became extinct. Scientists say the extinction of the mammoths was a combination of climate change and human intervention. Neanderthals hunted the large animals about 10,000 to 40,000 years ago encouraging the megafauna extinction. In the Americas nearly 75 percent of all animals weighing more than 100 pounds disappeared after humans arrived. At this time, scientists are still unsure of which of the two factors killed off the mammoth discovered in Oklahoma but are performing further…

thousands of years. Secondly, the extinctions of the large mammals directly correlate with the appearance of humans in those regions. Humans would have also targeted the large mammals as a primary desired food source. Additionally, the large megafauna in Africa had evolved together with the humans in the area, and thus the large mammals understood that humans were dangerous and adapted to living among humans. On the contrary, the large mammals in northern Eurasia and the Americas had never…

The Pygmy three-toed sloth is an endangered species of the South American Amazon rainforest, and there is estimated to be less than 100 individuals remaining. The sloth has pale grey-brown fur and a tan-colored face with a distinctive dark band around the eyes. On the sloths fur you’ll see a greenish tint which is actually a unique species of symbiotic algae, which helps them camouflage. Little information is know about the life span of the pygmy three-toed sloth, but most species of sloths live…

According to National Geographic, the Giant Sloth, the Cuban Red Macaw, the New Zealand Giant Moa, the Tasmanian Tiger, and the Woolly Mammoth are all among the faction of species that are extinct but that could possibly be revived. In fact, a poll issued on National Geographic’s website allows users to simply and effortlessly vote for which extinct species they would like most to see resurrected. Astonishingly, scientists have actually finagled a way to potentially make this poll useful.…

Almost the entire skeleton of a mammoth was dug up in Michigan, and it has raised many questions as to what exactly happened to the woolly mammoth, the great best of the Ice Age. Did Humans Kill the Mammoth? Dan Fisher, paleontologist Dan Fisher proposes that prehistoric people may have killed and butchered the newly discovered mammoth, and what they didn’t consume immediately was refrigerated in the depths of a frigid lake. Other scientists argue that there is no certainty as to what killed…

In the novel “The Sixth Extinction” by Elizabeth Kolbert, humans are destroying the world by burning fossil fuels, polluting oceans, rivers, lakes, and the air but, is it really the individuals human 's fault or is it corporations caring too much of profit that they will do anything to make an extra pennie? How many times have you heard about oil spills? Personally I have lost count of the ever increasing number of oil spills. Deforestation is also caused caused by corporate greed acording to…

species that reside there. In his article, Corwin begins his argument by relating the extinction of several current day species to that of the Holocaust. He vividly describes a situation in which nearly fifty percent of all living species have become extinct and the world is facing a “global crisis” (472). Corwin then goes on to address the cause of this mass extinction, us. In his article, Corwin explains that humans are currently the cause of so many species going into extinction and only we,…

Bison, or buffalo, are the tallest mammal in North America standing at six and a half to twelve and a half feet from feet to head, that is taller than an average male! Many breeds of bison are around the world, North American, European, and the Wisent are all breeds of the bison. The North American and European bison live on flat plains with fresh grass, which is a buffalo’s most common food they eat, but the bison in North America are only located along the west side of the U.S. Bison are…

The anaconda, also known as the green anaconda, is the heaviest, largest, and second longest snake in the world. The only snake larger than it is the reticulated python, found in Southeastern Asia. Male anacondas are usually 3-3.5 meters, while females range from 4.6-5 meters long. Anacondas are only found in South American countries which are east of the Andes mountains, such as Bolivia, Columbia, Venezuela, Guyana, Peru, Brazil, Paraguay, and Ecuador. They mainly live in the Amazon river basin…

dystopia has no occasion to be talked about because the risk of this situation is equal to the risk of invasion of aliens. Changlong Shi claims that the desire of the human being causes almost all global problems, which can be considered as the elements of dystopia. Firstly, he argues that racism, one of the most serious discriminations, is caused by the desire of the human being (Shi). He said that “it is generally accepted that the group of black people suffers racism. Some people think that a…
