How and when the first people landed up in the Americas, has always been a topic of passionate debate. We know they inhabited this land around 16,500 years ago, but we never really asked “how?” The Land Bridge Theory, The Coastal Theory, The Atlantic/ Pacific Theory, The African Theory, and The Native Perspective, are generally accepted theories of how the first people got to this side of the world. Despite the fact that these are just theories, several people make them out to be true. The Land Bridge Theory states that the first people, walked in search of food due to shortages in their native place. It is also said that the people followed the herds across the Bering Strait and landed in North America. People who believe the Coastal Theory claim that North America was connected to the rest of the world by a series of islands that no longer exists. Next up, the Atlantic/Pacific Theory. Those who believe this theory, state that people built boats and crossed the oceans to get to North America from places like Alaska. The African Theory states that people built boats to get from Africa to North America and then down to populate South America. Finally, the Native Perspective. Those who assume this theory to be true, is based less on evidence and DNA matches and more on spiritual beliefs.The most widely accepted theory of al six theories is the Bering Land Bridge Theory. It was in 1950, that the Spanish Missionary Fray Jose de Acosta produced a written record to suggest the building of the Bering Strait. The Bering Strait is an 82 kilometre strait that connects Russia to North America. This theory states that the native people were looking for ways to hunt larger animals due to lack of food in their area. The larger animals moved across Bering Strait and the people followed suit, hence landing up in North America. They then later moved down North America and then to South America, populating America. With low water levels and spreading ice caps, Beringia is said to have connected the Native Americans to America. Like most people in North America, I too believe this theory. The reasons as to why I suppose this theory to be correct is because scientists have found pieces of pottery, hunting tools, and a variety of other artifacts in the shallow waters of Bering Strait. These pieces of evidence could be true as the people would have needed tools in order to build boats and walking tools such as sticks, and possibly even shoes to cross the bridge. Moreover, DNA tests prove that the native groups in North America have similar DNA patterns to the natives in north western Asia. I presume this theory to be true also because it seems highly possible that there may have been a strait connecting Asia to North America as water levels were much lower than what they are today. This may have been because of the amount of available water or the shape and volume of the ocean basins. Also, the strait was covered in ice sheets due to freezing temperature. However, today, there is only water between Asia and North America, though evidence such as hunting tools and DNA patterns to prove that the Bering Strait did exist. Either way, it is a high possibility that people crossed the Bering Land Strait to get here.However, there are several researchers that believe Beringia was flooded before the people had a chance to cross into North America. This challenged the idea that the Land Bridge was only a route in and people had to build boats and ferry themselves to populate the rest of the Americas. Backing for this theory has been found in the form of DNA extracted from a 10,000 year old tooth. Researchers found that only one percent of modern natives they sampled had the tooth’s genetic markers. However, other genetics’ researchers suggest that the first people lived on the Bering Land Bridge for several years before crossing of to the Americas due to it’s exceeding length.
