Fluxus is an international and interdisciplinary group of artists, composers, designers and poets that took shape in the 1960s and 1970s.
 Dutch gallerist and art critic Harry Ruhé describes Fluxus as "the most radical and experimental art movement of the sixties".
 Fluxus is known for experimental contributions to different artistic media and disciplines.
 Fluxus is also known for generating art forms that were new when Fluxus artists created them.
 These art forms include intermedia, a term coined by Fluxus artist Dick Higgins, concept art, first developed by sometime Fluxus artist Henry Flynt, and video art, first pioneered by Nam June Paik and Wolf Vostell.

 It is the main constituent country of the Kingdom of the Netherlands.
 The European portion of the Netherlands borders Germany to the east, Belgium to the south, and the North Sea to the northwest, sharing maritime borders in the North Sea with Belgium, the United Kingdom, and Germany.
 The four largest cities in the Netherlands are Amsterdam, Rotterdam, The Hague and Utrecht.
 Amsterdam is the country's capital, while The Hague holds the Dutch seat of parliament and government.
 The port of Rotterdam is the largest port in Europe and the world's largest outside east Asia.
 Utrecht is a central node for road and railway communications, commerce, and cultural events.
In human genetics, the Y-chromosomal most recent common ancestor (Y-MRCA, informally known as Y-chromosomal Adam) is the most recent common ancestor (MRCA) from whom all currently living humans are descended patrilineally.
 The term Y-MRCA reflects the fact that the Y chromosomes of all currently living males are directly derived from the Y chromosome of this remote ancestor.
 The analogous concept of the matrilineal most recent common ancestor is known as "Mitochondrial Eve" (mt-MRCA, named for the matrilineal transmission of mtDNA), the most recent woman from whom all living humans are descended matrilineally.
 As with "Mitochondrial Eve", the title of "Y-chromosomal Adam" is not permanently fixed to a single individual, but can advance over the course of human history as paternal lineages become extinct.
