text: Where the canoe played a key role in history, such as the Northern United States, Canada, and New Zealand, it remains an important theme in popular culture. For instance, the birch bark canoe of the largely birch-based culture of the First Nations of Quebec, Canada, and North America provided these hunting peoples with the mobility essential to this way of life.
  Canoes are now widely used for competition — indeed, canoeing has been part of the Olympics since 1936— and pleasure, such as racing, whitewater, touring and camping, freestyle and general recreation.
  The intended use of the canoe dictates its hull shape, length, and construction material. Although canoes were historically dugouts or made of bark on a wood frame, construction materials later evolved to canvas on a wood frame, then to aluminum. Most modern canoes are made of molded plastic or composites such as fiberglass, or those incorporating kevlar or graphite.
  History
  The word canoe came into English from the Spanish/Portuguese word canoa, which in turn was  adopted from the Arawakan languages of the Caribbean for a dugout canoe, kanawa.
  Dugouts
  Many peoples have made dugout canoes throughout history, carving them out of a single piece of wood: either a whole trunk or a slab of trunk from particularly large trees. Dugout canoes go back to ancient times. The Dufuna canoe , discovered in Nigeria, dates back to 8500-8000 BC. The Pesse canoe, discovered in the Netherlands, dates back to 8200-7600 BC. Excavations in Denmark reveal the use of dugouts and paddles during the Ertebølle period, ().
