The first piece of evidence that supports the land bridge theory or the Clovis theory is that during the ice age in the Pleistoraene Era, the sea levels would have been lower in the Bering sea (Lebel & Orr). Because or the low sea levels there could have been a grassy plain known as Beringia linking Siberia with Alaska (Lebel & Orr). This evidence suggests that there would have been a path in which the first peoples could have traveled by. The distance would have only been seventy kilometers apart.…
Lastly, the last part of the paper will connect the historical evidence to the theories to prove whether or not the theories are supported.…

2. There are many scholarly disagreements about the research described in 1491. If our knowledge of the past is based on the findings of scholars, what happens to the past when scholars don’t agree? How convincing is anthropologist Dean R. Snow’s statement, "you can make the meager…

A: The book states that in order for something to be considered scientific there must be some test or possible observation that could disprove it, if there is not a way to disprove it, and then it cannot be supported by science.…
It is said that sometime 10,000 years ago, the people from China are believed to have crossed over the Bering land bridge from Siberia to what is now Alaska. From there, they are believed to have spread out over the course of millennia. Once they got here they started diverging genetically and populating North and South America. The problem is that the only real evidence they have is maps and some artifacts, which from carbon dating trace back to 2200 B.C. These generally have been found on the coasts of Florida, South Carolina, New York and Canada.…
The well known ecologist Charles Darwin exhibited the hypothesis of natural selection. He went on numerous trips to the wildlife, taking after his interest of the nature and the change that happens in the nature. After examining different kinds of living organisms, he clarified Natural Selection as "preservation of favorable variations and the rejecting of injurious variations."(900). Darwin utilized relations and demonstrations to show that distinctive changes happened in the same specie, which assisted them with adapting to their environment.…
The logical fallacy that Sarah has fallen into is the “ad hominem”, it tends to discard a theory not because of the lack of evidence or any evidence that runs against it, but it is totally depending on an individual person who argues for it.…

The geological record does not support Darwin’s theory because there are no intermediate species found in fossils and sometimes groups display abrupt modifications. However, this can be the result of changes in the earth’s surface, unfitting conditions for fossil formation, the destruction of existing fossils, and the lack of discovery of fossils. Darwin uses these possibilities to argue against the naturalists, saying that there is not enough knowledge about the history of earth to draw conclusions on…
When you’re trying to prove a discovery videos, sightings and footprints aren’t solid evidence because scientist can tamper with their videos, sightings and footprints to make believers believe what they want them to see which would result in not being true. With the technology in today’s society scientists don’t have a problem animating or editing videos to make believers believe about a Sasquatch and making it look real. When in realty Sasquatch doesn’t exist at all because there has been no real discovery of it.…
Scientists do not believe in the theory that the flood from the Bible was the cause of the ice age because they don’t think this provides enough evidence as to how it all began, but other people do believe that there is evidence onto how it all began and how it had happened. Although the bible contradicts most science theories, some people do believe this theory.…
Natural Selection is when each generation of a species develops new characteristics and adapts more to the environment to survive. This theory of evolution caused some controversy because it contradicted the beliefs of many religious leaders. It also caused scientists studying the field to reevaluate everything that they had learned! Some people tried to use this theory to justify acts like slavery and genocide. Natural Selection was used to imply that these behaviours were natural.…
Theories are generally formulated and to explain unsolved matters based on available evidences. However, considering the available credible explanations of UFOs and government’s relation to it, conspiracy theories can be considered as merely interpretation, speculation with no credible data. According to Benjamin Radford in UFO Conspiracy Theories has Holes, UFO conspiracy theorists have a difficult time explaining why world are so concerned about the public being aware of aliens and what the purpose of a cover-up would be (Radford). Furthermore, Neumayer UFO is another sighting that occurred in the Antarctica, which a video of the identifying object was videotaped and put on YouTube. Benjamin wrote that “if it was indeed a spacecraft instead of a balloon or some other mundane object, why would the government – which routinely accused of going to extraordinary lengths to cover up all evidence of aliens – intentionally release the video to the public? “ (Radford). This is due to the fact that theorists don’t have credible evidences, or scientific evidences to hold their theoretical ground, which then can cause the theories to be only speculation.…
