Much archaeological evidence supports the widely held view that the first people to migrate to the American continent entered through a land bridge, which at one time joined Eastern Asia with North America. This land bridge, known as Beringia, was a wide

According to the lecture, the different evidences suggests that the early inhabitants of Americans dated back earlier than what Clovis-first theory suggests. In contrast, the author explains that first people to migrate to America continent entered through land bridge called Beringia during ice age from Asia. First of all, the author points out that the people from Eastern Asia migrated across the grassy tundra of Beringia which at the time was fully covered with ice sheets. However, the lecture refutes this by explaining that ice sheets which covered land mass would have make the travel not difficult. Secondly, although the Clovis period was 11000-13000 years ago, many archaeological evidence were found to be older than Clovis. Furthermore, the lecturer provides evidences that the site of eastern United states was 19000 years old and of South America was 15000 years old which was way before Clovis period. The lecturer cast doubts about Clovis-first theory by explaining that the dating techniques provide evidences of record 15000 years ago and he further argues that it would have taken century to pass the huge Beringia. Thirdly, the lecturer mentions that the older remains don’t look like native American rather it fits to pacific or norther Japan. He further puts his view that many American resembles Siberian which might have migrated around 40, 000 years ago. Lastly, he explains there were different people from different area that traveled to America which is extremely complex. Thus, the Clovis theory is doubtful.
