Explanation:
Tribal territories and the slave trade ranged over present-day borders. Some Native American tribes held war captives as slaves prior to and during European colonization. Some Native Americans were captured and sold by others into slavery to Europeans, while others were captured and sold by Europeans themselves. In the late 18th and 19th centuries, a small number of tribes adopted the practice of holding slaves as chattel property, holding increasing numbers of African-American slaves.
European influence greatly changed slavery used by Native Americans, as pre-contact forms of slavery were generally distinct from the form of chattel slavery developed by Europeans in North America during the colonial period. As they raided other tribes to capture slaves for sales to Europeans, they fell into destructive wars among themselves, and against Europeans.

The remnants of dozens of mammoths whose furs, tissues and internal organs were preserved intact for thousands of years in the ice and permafrost of Siberia have been examined by scientists who autopsied the bodies determined that many of these animals died suddenly as a result of fatal falls into crevices and holes hidden in the terrain. Other are believed to have died during violent blizzards that got the mammoths into a state of hypothermia very quickly.
