This article examines a National Geographic news article relating to the history of the first Americans entitled "En route to the New World, the first Americans made a pit stop of 10,000 years ". The first Americans may have remained on the Bering land bridge after separating from Siberia, which would explain some things about the genetic variances between the two groups. Why does research think early Americans lived on the Bering Land Bridge? Are the reasons for believing in it justified? This article attempts to answer these questions. This National Geographic article is based on a recent study conducted by Dennis O'Rourke and two colleagues. O'Rourke and colleagues' study suggests that early Americans may have lived in Beringia for 10,000 years. (Than, 2014) This idea is not new; This is called the rolling cessation hypothesis. This hypothesis states that the first Americans probably lived elsewhere for a long period, after separating from the Siberian population, before landing in Alaska. (Than, 2014) The reasoning behind this hypothesis is that archaeological evidence has shown that the oldest site of early Americans was approximately 15,000 years old, while genetic evidence shows that early Americans split off from Siberia ago approximately 25,000,000 years ago. (Than, 2014) It was assumed that early Americans lived in Beringia, but there was no archaeological evidence to support this speculation and Beringia was considered inhospitable. However, according to this article, O'Rourke and colleagues' study shows that Beringia might actually have been hospitable. Examination of sediment cores from the Bering Sea and Alaskan peatlands revealed that Beringia may have contained trees such as birch, willow, spruce, alder, and bushy shrubs. This setting, according to O'Rourke, made...... middle of paper ......age from Siberia to arrive in America. An argument against Feders' theory could have been: the first Americans did not come from Siberia because it takes about 25,000 years for DNA to change and the first Americans arrived about 13,000 years ago. This article shows that it is likely that the first Americans came from Siberia. This article also discusses Clovis culture, linking it to early Americans through genetics. Feder also talks about Clovis culture in his book and highlights the debate over its origins. However, it appears that with genetic evidence showing that a young boy from the Clovis culture shared DNA with early Americans, this debate will come to an end. In conclusion, it seems very likely that the first Americans settled in Beringia for 10 millennia. This article presents good evidence for the status quo hypothesis while objectively discussing other views..
