What is the evidence of the asiatic theory?
The Asiatic theory suggests that Native Americans originated from Asia and migrated to the Americas via the Bering Land Bridge. Evidence supporting this theory includes genetic studies showing similarities between Asian and Native American populations, as well as archaeological findings of ancient tools and artifacts in both regions that are similar in style and construction. Additionally, linguistic studies have identified similarities between certain Native American languages and languages spoken in Siberia.
What does the land bridge theory explain form about 10000?
The land bridge theory suggests that around 10,000 years ago, a land bridge called Beringia connected Asia and North America, facilitating the migration of early humans into the Americas. This theory helps explain how humans first populated the Americas by crossing from Asia into North America.
Where is the land bridge linked?
Land bridge theory it was believed that land bridges could explain the occurrence of species in separate continents and the resemblances of geologic formations on different continents. Many land bridges were criss-crossing large areas of ocean. However, when the sea bed of the Atlantic Ocean was mapped using echo sounding between 1924 and 1927, no remains of land bridges could be found. Though this was a strong argument for Alfred Wegener's theory of continental drift, it would take about 50 more years until mainstream geology fully acknowledged the motion of continents.
How Wegener try to prove the theory of continental drift?
Alfred Wegener proposed the theory of continental drift in 1912. He collected evidence from various fields, such as the fit of continental coastlines, matching rock types and structures across continents, and similar fossil distributions. However, his theory was not widely accepted until decades later when the concept of plate tectonics provided a mechanism for how continents could move.
American biologist who provided evidence for the endosymbiotic theory which explains the origin of chloroplasts and mitochondra?
Lynn Margulis is the American biologist known for her work on the endosymbiotic theory. She proposed that chloroplasts and mitochondria evolved from ancient prokaryotic cells that were engulfed by a host cell. Her research provided evidence supporting the idea that these organelles have their own DNA and replicate independently within eukaryotic cells.
The theory that Native American Indians migrated across a land bridge from Asia to settle in North America is based on?
They crossed over the land bridge called Beringia
What is the most popular theory as to how the early American Indians came to live in the north American continent?
The most popular theory would be that they traveled across the Barring Straight Land Bridge.
Where did I dians first land in America?
No one knows how the Native Americans got to America, but there is a theory called the "land-bridge theory" that offers an explanation that many agree with. The northern American aboriginals walked across from Siberia to Alaska thousands of years ago when the ice age froze up huge amounts of water in the Bering Strait.
The earliest inhabitants of North America were thought to have come across a bridge of land thousands of years ago?
Yes, this is a theory which is believed by many people in the modern world today, it is believed that people from Russia and Siberia crossed the Baring Strait when it was frozen over 20 000 - 40000 years ago and spread out across North America, and when settlers came they became know as Native Americans. However Native American's refute this theory and state they have lived on the land since the beginning of time itself.
How did the native American Indians get to the Americas?
Some will tell you that they have always been here. My belief is the land bridge from Siberia. Ocean crossings has become a popular theory as of late but doesn't offer a large population change. We do know Native American's go back to the ice age.

Most original Native American governments lend support to the?
evolution theory
How did the first native Americans probably reach north America?
The truth is we don't know. The common theory has been by walking across the Bering Land bridge, but equal evidence supports by sea from Europe, Asia, and Oceans by hundreds to tens of thousands of years earlier.
Where did the first American live?
According to the currently most accepted theory, the first people to occupy the Americas came across a huge ice bridge that connected northeastern Asia with what is now Alaska toward the end of the last Ice Age.
How did the first humans arrive in US?
It is believed that there was a land bridge between the area of present day Russia and Alaska. People walked across for a still unknown reason, it is thought they were chasing food sources. They then spread out all over the North and South American continent and formed the Native American Tribes.
Should Native Americans be given greater credit for helping develop the theory behind the American system of government?
Almost all of the theory behind the American system of government was developed long before George Washington discussed it with Native Americans. The main Native American contribution was to show that such a government actually worked in practice for a secular government and not just for a religious one.
Why couldn't people from the Western Hemisphere discover the continents in the Eastern Hemisphere?
Modern science supports the theory that humans in North and South America migrated from Asia across a land bridge that connected Alaska and Siberia. Because of a more simple culture among Native Americans, advanced ship building was never necessary, and therefore travel across the oceans was not possible.
