Land Bridge Theory As Evidence Of Migration To America

Imagine a long, long time ago, an Indian holding a spear in his hand. He pulls it back, and launches it at a wooly mammoth. How do you think humans migrated to America? There are several theories such as the Land Bridge, the Clovis theory, the Coastal Route theory and many other theories as well. I think they got here using the Bering Land Bridge. Many people may not have heard of the Land Bridge theory before. In the following paragraphs I will explain to you the Land Bridge theory, as well as evidence of the land bridge being used for the people to migrate to America. “What is the Land Bridge theory,” you may ask the following question. Well, the Land Bridge theory, which is also known as the Bering Strait theory, is a model of migration
Scientists have done several studies on DNA to try and make connections as proof of the Land Bridge being used for the migration to North America. In doing more than a dozen studies, geneticists studied modern and ancient DNA samples from Native Americans, looking for genetic mutations that define human lineages. They found that native people in the Americas went off of four major lineages. To find the start of the lineages, the geneticists searched for human populations in the old world whose genetic diversity included all four lineages. Only the modern inhabitants of southern Siberia matched the genetic profile, this is a discovery that indicates that the ancestors of the first Americans came from an East Asian
One of the articles I read, which was titled “Land Bridge Theory,” suggested that the people that were migrating to America across the Land Bridge were dressed in warm, tailored hide garments that were stitched with bone needles by an expert during that time. The weather conditions would definitely not have been the best for traveling. Huge glaciers would have capped the valleys of Asia, at the same time ice sheets covered most of Canada, New England and several other northern states. Based on the data saved in the ice cores from Greenland and the measurements of the sea levels in the past, it shows that the ice sheets reached their maximum length at least 22,000 and 19,000 years ago. David Meltzer, an archeologist at Southern Methodist University, states, “Their entire existence – and the existence of everyone they knew and the existence of their ancestors – was about adapting. They had a toolbox of tactics and strategies.” This quote is basically saying that the people migrating into America would have needed to adapt, and whether or not they could adapt, and how they adapted would affect the
