1. Why did early humans migrate to North America?

Early humans might of migrated because of food.  They might of killed off the animals and had to move to survive.  Also, they might of moved because of the climate change.  It might of gotten to hot and they would have to move.  “In fact, so many animals got killed that some of them became extinct.  But, in most cases, their disappearance wasn’t because of the hunters… After the Ice Age when the climate, warmed up, mammoths could not adjust.”  (Blue Book).

2.  Who were the 1st Americans?

I think the first Americans were the Indians.  I think that they came over the land bridge to the Americas and settled there.  They were not Native because everyone’s ancestors was born in a different place.  So I believe people from Asia were the first Americans.  “Genetic findings suggest that a single population of modern humans migrated from southern Siberia toward the land mass known as the Bering Land Bridge as early as 30,000 years ago, and crossed over to the Americas by 16,500 years ago. Archaeological evidence shows that by 15,000 years ago, humans had made it south of the Canadian ice sheets.”  https://www.nps.gov/bela/learn/historyculture/other-migration-theories.htm

1) Why did the the early humans migrate to America?

The early humans migrated to North America for many reasons . One of the reasons the early humans of the climate change. The climate change probably caused the early humans to migrate because it was probably hard for humans to live and survive at different temperatures  and hard to grow and harvest crops. Another reason for them to migrate is because of them being nomadic. Being nomadic, they could have been chasing after the animals and searching for new hunting grounds. (Source: Blue Book.)

2) Who were the first Americans?

The first Americans were to be believed as the descendants of Northeast Asia. The fist Americans were to be traveling across a land bridge that had connected Siberia and Alaska. This had happened about 12,000 yearsago.http://news.nationalgeographic.com/news/2003/09/0903_030903_bajaskull.html

1.Why did early humans migrate to North America?

The early humans migrated for many different reasons but the opportunity came when the ice age started. The ice sank sea level and created a land bridge between russia and Alaska. The animals they hunted were going extinct and so naturally they looked for new settlements.

2. Who were the first Americans?

According to http://news.nationalgeographic.com/news/2003/09/0903_030903_bajaskull.html
The first americans were southeast asians and came around 13,500 years ago to north america and they formed different tribes all along america and crossed the Bering Strait. They all had different ways of living, whether farming or hunting, or nomadic and permanent shelters, they were native americans.

1. Why did the early humans migrate to North America?

I believe that the early humans moved to north america because some of the early tribes moved around and followed their food to survive. Another example is that after the Ice Age the big animals started to leave for colder places and early humans followed them. My last reason is the weather. during the Ice Age the temp. went up making it hard for them to farm and hunt where they were.
(Blue book)

2. Who were the first Americans?

he question of who colonized the Americas, and when, has long been hotly debated. Traditionally, Native Americans are believed to have descended from northeast Asia, arriving over a land bridge between Siberia and Alaska some 12,000 years ago and then migrating across North and South America.
But recent research, including the Baja California study, indicates that the initial settlement of the continent was instead driven by Southeast Asians who occupied Australia 60,000 years ago and then expanded into the Americas about 13,500 years ago, prior to Mongoloid people arriving from northeast Asia.

1. Why did the early humans migrate to North America?

It might have become too hot, cold, wet, dry or humid to live in the area so they had to move. Climate change also then affects food supply, which might have led them to migrate in search of food AND better living conditions. Also the fact that the food the were hunting for many years was becoming extinct. Link

2. Who were the first Americans?
Asians from northeast asia near siberia (according to national geographic) because when they came over from the land bridge, the other end of the bridge was Asia therefore they were Asians from the siberia area and northeast asia. http://news.nationalgeographic.com/news/2003/09/0903_030903_bajaskull.html

1. Why did early humans migrate to north america?

One reason why early humans migrated to north america could have been from the climate change. The ending of the ice age made most of what they hunted extinct. Another reason why they migrated to north america was because of a land bridge that connected Asia and north america. Scientists believe that early humans traveled on that to follow herds of animals they hunted.

2. who were the first americans?

recent research has shown that Southwest Asians who resided Australia 60,00 years ago, then came to the americas about 13,500 years ago. Baja California has found skulls with slender faces which has maybe only have been from only 100 years ago. in 1996, archaeologists in southern Chile found tools from 12,500 years ago. In Brazil, they found some of the oldest human remains in the americas, that is more than 11,000 years old.

1.) Why did early humans migrate to North America?

The early humans migrated for many reasons , First of all the large animals they usually hunt started to become extinct when the ice age began to end. They also moved to North America because there was a lot of land to discover. Also, their land changed because of the ice age so temperatures went up making it harder to live where they were.
( Blue book)

2.) Who were the first Americans?

Some believe that the first Americans were people from Asia that crossed the land bridge from Siberia to Alaska 12,000 years ago then migrating across North and South America. But recent research shows that the first settlement was instead driven by Southeast Asians in Australia to expand into the Americas 13,500 years ago.

1.) Why did early humans migrate to North America?

Early humans migrated for many reasons. First off they large animals they were so used to hunting began to go extinct when the ice age ended. Another reason the may have migrated was because of drastic temperature and climate changes. The weather they were so used to changed so they had to find a different source to get food.

1. Why did early humans migrate to North America?

Early humans migrated for many reasons. One reason they migrated was for food. Early humans followed the prey from Asia to America.They usually preyed on bigger animals like mammoths and bison. But the early humans had over hunted and had to find new sources of food. Another reason why early humans migrated was because of climate change. The temperature rose and caused all of the Ice caps and glaciers to melt. This caused floods that forced people to migrate. For more information click the link below.

2. Who were the first Americans?

The first Americans were Early humans that migrated from Asia using the landbridge. They eventually settled down and became the Native Americans we know today. The Asians crossed a land bridge between Alaska and Siberia. For more information click the link below. http://news.nationalgeographic.com/news/2003/09/0903_030903_bajaskull.html

Who were the first Americans?1. Why did early humans migrate to north America?

The humans migrated so they could find food, because they killed all the animals.  They needed more food so they moved to north America to start over until food is gone a again.

1. Why did the early humans migrate to America?

People Came to America
because they were in search of food, due to the climate and over hunting problems. Also they could have come because they were Nomads which also ties back to food, because Nomads are people who travel from place to place i search of food, Also One idea is that the conditions at home were so bad that they decided to migrate. Finally, People could have migrated due to land conflicts and conflicts over hunting grounds.

2. Who were the first Americans?

The First Americans were most likely East Asians that traveled across Beringia (the land bridge) and settled down and whose ancestors became the native americans we know today. They Most likely came around 13,500 years ago. These people were most likely Nomads who traveled in search of new hunting Grounds.

1.Why did the early humans migrate to North America?

The early humans migrated for many reasons, the Beringia theory is one. Scientists believe the bridge was used for people to go to Alaska from Siberia. The early humans used this land bridge to track large herds of animals for food. Climate change is one of them as well. These early humans traveled to get away from the cold. They migrated to somewhere warm and had more herds. The Asian Arctic was a problem too, the ice sheets where covering up the north of Asia and literally sucked up the earth. This made sea levels drop almost 300 feet. Almost 15,000 years ago the people penetrated the land south of the ice. Within 1,000 years, with the help of the land bridge, the early humans made it to the tip of South America.

2. Who were the 1st Americans?

It is known that the Native Americans came by the land bridge 12,000 years ago then migrated across North and South America. All though, recent studies including the Baja California study show that the settlement of the continent was driven by the Southeast Asians who "owned" Australia more than 60,000 years ago and then expanded to the Americas. "Our results change the traditional idea that all modern Amerindians present morphological affinities with East Asians as a result of a single migration," said Rolando González-José of the University of Barcelona, Spain. If the Native Americans didn't come first, did the Southeast Asians come before them? Need to cite this source.

1. Why did early humans migrate to North American?

Early humans migrated to North America because wherever they had been, the climate could've been changing and made it hard to live there. If the climate is changing, it would be hard to grow crops and harvest there.  Another reason early humans migrated to North America is because they were nomadic. They could've been 'chasing' the animals and hunting as they were exploring new land, without even knowing it.  Maybe, the early humans were being chased. There wasn't as strong of a government then as there is now, so they could've been in a war.  Another theory is that they came here because they could. According to studies, humans seemed to have a 'universal penchant for moving around' which basically means they were very laid back and were ok with people moving around.

2. Who were the first Americans?

Although it is traditional to think that Native Americans were the first Americans, recent studies are showing that it might have been Southeast Asians who occupied Australia 60,000 years ago and then expanded into the Americas about 13,500 years ago, prior to Mongoloid people arriving from northeast Asia. This was discovered when some archeologists found some skulls off the coast of Baja California. Also, in 1996, archaeologists in southern Chile found ancient weapons. When they got the results from the radio carboning, they learned that the weapons were from 12,500 years ago. Also, in Brazil they found some of the oldest human remains in the Americas, among them a skeleton that is more than 11,000 years old. The skeleton was named Luzia. Luzia didn't look like that American Indians. Her facial features just didn't match theirs. She looked more like the native Aborigines in Australia. These researchers believe that Luzia is a part of the people that go by the name Paleoamericans.  Scientists have done a lot of research and they have compared Luzia's skull to many different ones. These skulls just don't have an of the same traits as the Native Americans we thought were the first americans.

1. Why did the early humans migrate to north America?

The early humans migrated to north America for several reasons. One of these reasons is that the large mammals they often hunted went extinct about 15,000 years ago, when the ice age began to end. The end of the ice age was another reason they migrated. The temperatures rose and glaciers began to melt, causing the environment they had lived in so long to change drastically.

2.Who were the 1st Americans?

The first Americans originally came from Asia, and to get to America they probably crossed a land bridge that used to exist in the Bering Strait, between Russia and Alaska. Some tribes were nomadic, others were farmers. There were many different tribes who had various methods for living, such as gathering food and water, and how they built their homes. All of these things depended on the climate. The Pueblo, who lived from A.D.1 to A.D. 1300, lived in the region of the four corners, and managed to farm in the desert through irrigation. The Adena were hunters and gatherers who lived in the Ohio River valley from about 800 B.C. to A.D.100. The Hopewell lived between 200 B.C. to A.D. 500. They were farmers and traders who built huge burial earthworks in shapes of birds, snakes, and bears. The Hohokam lived from about A.D.200 to A.D.1400 in Arizona. They irrigated water to their crops by digging hundreds of miles of channels. They produced pottery, carved stone, and etched shells with acid. Sometime after A.D.900, the Mississippians were alive, and they built some of the largest known earthworks complex in present day Illinois.

1.Early humans migrated to North America for many different reason, but one stood out the most is that their climates changed, Many people support this answer like  Meredith F. Small who is a Professor at Cornell University, she says that ¨the climate had changed and made life impossible. It might have become too hot or too cold or too wet, which in turn would have affected not only quality of life but also make survival a shaky proposition." This shows that it might have been because of the climate they moved North, Another reason is they might have lacked the food they needed this also connects to the climate because if they lack food from the climate they would need a new source of food.

2.The 1st Americans could have been anyone but a lot of sources say that it was most likely that the Asians travelled over a land bridge in the ice ages, one source states that the first people came from Asia also another source states written by Mohi Kumar a Scientific Content Editor for AGU's Eos. states that¨New genetic evidence supports the hypothesis that the first people in the Americas all came from northeast Asia by crossing a land bridge known as Beringia. When sea levels rose after the last ice age the land bridge disappeared." this states that more the first Americans were actually Asians that were found in America 9000 years ago.
