DNA profiling in the context of "Forensic biology"

Genetic genealogy is the use of genealogical DNA tests, i.e., DNA profiling and DNA testing, in combination with traditional genealogical methods, to infer genetic relationships between individuals. This application of genetics came to be used by family historians in the 21st century, as DNA tests became affordable. The tests have been promoted by amateur groups, such as surname study groups or regional genealogical groups, as well as research projects such as the Genographic Project.

As of 2019, about 30 million people had been tested. As the field developed, the aims of practitioners broadened, with many seeking knowledge of their ancestry beyond the recent centuries, for which traditional pedigrees can be constructed.

Hōkūleʻa (Hawaiian pronunciation: [ˈhoːkuːleʔɐ]) is a performance-accurate waʻa kaulua, a Polynesian double-hulled voyaging canoe. Launched on 8 March 1975 by the Polynesian Voyaging Society, it is best known for its 1976 Hawaiʻi to Tahiti voyage completed with exclusively traditional navigation techniques. The primary goal of the voyage was to explore the anthropological theory of the Asiatic origin of native Oceanic people (Polynesians and Hawaiians in particular) as the result of purposeful trips through the Pacific Ocean, as opposed to passive drifting on currents or sailing from the Americas. DNA analysis supports this theory. A secondary project goal was to have the canoe and voyage "serve as vehicles for the cultural revitalization of Hawaiians and other Polynesians."

Between the 1976 voyage and 2009, Hōkūle‘a completed nine additional voyages to Micronesia, Polynesia, Japan, Canada and the mainland United States, all using ancient wayfinding techniques of celestial navigation. On 19 January 2007, Hōkūle‘a left Hawaiʻi with the voyaging canoe Alingano Maisu on a voyage through Micronesia (map) and ports in southern Japan. The voyage was expected to take five months. On 9 June 2007, Hōkūle‘a completed the "One Ocean, One People" voyage to Yokohama, Japan. On 5 April 2009, Hōkūle‘a returned to Honolulu following a roundtrip training sail to Palmyra Atoll, undertaken to develop skills of potential crewmembers for Hōkūle‘a's eventual circumnavigation of the Earth.
