What is the history of Paleo-Indians? how did they appear in america?

Paleo (means ancient) Indians are considered to be the oldest known people to occupy the Americas.  They were commonly found in the southwest and New Mexico in America.  They were the longest running culture in America and existed for a period of around 30, ooo years.  There has been limited evidence of their existence.  They were a nomadic tribe that traveled from one region to another to cope with seasonal changes.  They traveled in groups of about two dozen people and brought their belongings on their backs.  They did not use any mode of support as they traveled by foot.  As time passed they migrated around other areas of the Americas.  Clothing consisted of things from nature such as plant fibers and animal skins.

To obtain food they gathered and hunted plants and animals.  Their techniques were simple and weaponry was limited.  They made simple stone and wood tools that they used for grinding seeds and cutting meats.  They used flint making skills and chipped off stone and bones to make useful items.  Most of the relics from their society have been found by large bodies of water.  Spear points were used for big game hunting but they mostly relied on small or weak animals.  Other hunting techniques include forming in groups and chasing an animal off of a cliff so that it would become injured or die.  They most likely hunted mastodons in the same manner that the Plains Indians hunted bison.

For thousands of years Earth’s land was covered and locked together by ice during The Ice Age.  Animals and humans are believed to have crossed the Beraing Straight, Beringia.  The Paleo Indians were nomadic and wander through into the Americas.
