The Late Quaternary Extinction happened approximately fifty to ten thousand years ago‚ and recently in the nineteenth century new light was shed upon why this extinction had happened and why it this extinction primarily targeted large animals. This extinction is vastly studied because it appeared to be more selective of large mammals than pervious extinction in North America. With recent advancements of carbon dating there has been hypothesis other than the over kill hypothesis which was primarily

There have been many investigated causes for this‚ but the scientific community cannot decide on one for sure. This is due to lack of evidence for each theory. The most common current theories about the extinction are over hunting‚ climate change and disease. One of the possible causes of extinction of the megafauna is climate change. This is predicted as the megafauna all around the world became extinct close to the end of the last ice age and just and the climate was getting warmer (Florek‚ 2015)

Memory is interpreted by scientists in mainly three different distinctions among the different types of memory. One of these distinctions is the distinction between episodic and semantic memory which are the distinctions within the declarative memory type. Episodic memory can be described as a recall of personal facts and can be more commonly known as memories of autobiographical events. These facts are a matter of how the person interpreted an event that they have remembered from their point of

The Sixth Extinction According to the information given by Niles Eldredge‚ about 30‚000 species go extinct annually. The first five major extinctions that have happened in the past were due to natural causes. The first started with severe and sudden global cooling and lost 25% of families. The second happened near the end of the Devonian Period and may or may not have been the result of a global climate change of which 19% of families were lost. Evidence suggests that a bolide impact similar

Biomes and Diversity Extinction is a natural selection process. Should humans strive to preserve a representative sample of all biomes or aquatic zones? Why should humans be concerned with the extinction rate? This is an interesting question. Lets consider the fact that it begins by stating extinction is a natural selection process. This seems to stifle one side of this argument.The side of the argument that rallies humans to be concerned with the extinction rate and strive to preserve a representation

In the article titled “Meteor likely caused the Earth’s Greatest Extinction Event” the author states that “About 60 meteorites five or more kilometers across have hit the earth in the past 600 million years. The smallest ones would have carved craters some 95 kilometers wide. “Most scientists agree that one such impact did in the dinosaurs‚ but evidence for large collisions coincident with other mass extinctions remained elusive until recently.”The increased attention brought about the discovery
