The first people to live in the Americas are referred to as Paleo
The first people to live in the Americas are referred to as Paleo-Indians. There are two viable theories on how these people ended up in the North America area. Both theories have scientific findings to support them, and it is entirely true both cases occurred many, many years ago.
The first theory states that a group of people traversed from what we now know as Siberia. The world was experiencing the Ice Age, which lasted for thousands of years. As a result of the Ice Age, the seas near the Bering Strait were frozen in ice caps. Consequently, the sea level had dropped almost 400 feet below the sea level and a natural land bridge was revealed situauted between Siberia and the Alaska region in the Bering Strait. Fossils discovered and carbon dating shows that hunters in search of mastodons, mammoths, and bison crossed over the land bridge to the Americas. The time frame for this theory indicates the Paleo-Indians arrival came about 15,000 years ago.
This theory has the hunters moving south to eventually form the nations of the Aztec, the Incas, and the Mayas. The Mayas were settled along the coast of the Gulf of Mexico such as at Chichen Itza, the Aztecs settled in central Mexico near what we now know as Mexico City, and the Incan villages were placed high in the mountains of Mexico and the Yucatan areas.
The second theory for people coming to the Americas is the coastal theory. The voyagers were thought to have arrived in small boats and landed along the shore areas. These people hunted whales, seals, and gathered shellfish along the ocean areas. There are found relics and dating as well to support this theory. These people came from Asia and landed on the coastal areas from Washington, California, and Mexico. They eventually worked their way to the west and down the coastlines of South and North America. It is thought that this migration happened about 40,000 years ago.
It is entirely possible that both scholarly theories are correct. The scholarly evidence certainly indicates this possibility. And what scholars are sure of is that 12,000 to 9,000 years ago the Ice Age ended as the climate began to warm. The combined warmer weather and influx of Paleo-Indian killed off the mammoths and other large mammals. The grasslands tended to shrink in land size as the wooded areas increased in size. With the extinction of the large animals, the hunters killed less and gathered more. The Paleo-Indians also began to develop skills of racking and hunting smaller animals. These style changes in survival and food gathering created an expansion through the North and South Americans.
The lands became more diverse, people scattered and explored in different areas, and the America’s became a group of 375 different spoken languages by 1492. All of these events occurred due to a land bridge trek and coastal voyages and landings many, many years ago.
