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 expanse of terrain that emerged from the ocean as the sea levels dropped due to widespread glaciation at the time of the last Ice Age. Groups of humans could have slowly migrated across the grassy tundra of Beringia, feeding on herds of animals or coastal marine life. At the time, much of North America including what is now Canada, would have been covered with thick ice sheets making further movement southward a physical impossibility.
At a later period, the ice receded and humans would have been able to traverse an ice-free corridor in a southerly direction, and gradually settle the vast uninhabited continent. The ending of the Ice Age also caused the ocean levels to rise, thus submerging Beringia and isolating the new migrants from peoples on the Asian side. During the next centuries the descendants of the pioneers who crossed Beringia gradually peopled the entire landmass of the Americas. This view of the origins of the first Americans is often known as the Clovis-first theory (named after the site in New Mexico where stone artifacts made by these settlers were first found). Many subsequent finds of Clovis tools demonstrate this culture's extensive penetration throughout the continent.
The article states that first people to migrate in American conten came from Eastern Asia through Beringla - a land bridge that joined both the continents during ice age. However, the professor explains that the many remains found didn't tally with the clovis first theory and refutes to each of the author's reasons.
First, the article states that due to ice age the water level of ocean dropped and a terrain emerged from ocean, which served as bridge. But the professor refutes to this point by saying that the ice sheets at that time would have prevented them from migrating.
Second, the professor says that the clovis theory estimated the time of migration about 11000 to 13000 years ago. While the professor pointed that many archelogical remains were found which dated back 19000 years. And with this evidenvce it can inferred that prior to this time people would have migrated here. And archelogical remains dated back 15000 year ago were also found in South America. The later one highlights that it took century for people to migrate to South America.
Third, the professor says that many remains found were essentially matching with the tradition from pacific island and japan. And adding to it the DNA analysis, the professor here mentions that the report gives a new prospect to this theory and shows that siberian people would have migrated 40000 years back. And from this the professor concludes that numerous difference have been in the data and the validity of this theory is doubtfull.
