Question: The Omphalos hypothesis is named after the title of an 1857 book written two years before which Charles Darwin book ?
Context: The Omphalos hypothesis is the pseudoscientific argument that God created the universe recently (within the past ten thousand years, in keeping with flood geology), but also introduced false evidence that the universe is of great age.  It was named after the title of an 1857 book, "Omphalos" by Philip Henry Gosse, in which Gosse argued that in order for the world to be "functional", God must have created the Earth with mountains and canyons, trees with growth rings, Adam and Eve with hair, fingernails, and navels ("omphalos" is Greek for "navel"), and that therefore "no" evidence that we can see of the presumed age of the Earth and universe can be taken as reliable.  The idea saw some revival in the 20th century by some creationists, who extended the argument to light that appears to originate in far-off stars and galaxies. Omphalos: An Attempt to Untie the Geological Knot is a book by Philip Gosse, written in 1857 (two years before Darwin's "On the Origin of Species"), in which he argues that the fossil record is not evidence of evolution, but rather that it is an act of creation inevitably made so that the world would appear to be older than it is.  The reasoning parallels the reasoning that Gosse chose to explain why Adam (who would have had no mother) had a navel: Though Adam would have had no need of a navel, God gave him one anyway to give him the appearance of having a human ancestry.  Thus, the name of the book, "Omphalos", which means 'navel' in Greek. The Life and Letters of Charles Darwin is a book published in 1887 edited by Francis Darwin about his father Charles Darwin.  It contains a selection of 87 letters from the correspondence of Charles Darwin, an autobiographical chapter written by Charles Darwin for his family, and an essay by Thomas Huxley "On the reception of the 'Origin of Species'". The BBC Darwin Season is a series of television and radio programmes commissioned by the BBC in 2009 to celebrate the bicentenary of the great naturalist Charles Darwin (1809-1882) and the 150th anniversary of the publication of his revolutionary book, On the Origin of Species in November, 1859.  In partnership with the Open University, the BBC produced a special documentary, Charles Darwin and the Tree of Life, narrated by David Attenborough, and three major series.  Other presenters involved are Andrew Marr, Melvyn Bragg and Jimmy Doherty.  The overall commissioning editor for the season is Martin Davidson, the BBC's commissioning editor for specialist factual (in-house).  Contributing units of the BBC are BBC Science, the Natural History Unit, the Religion and Ethics department and the children's channel, CBBC. On the Movements and Habits of Climbing Plants is a book by Charles Darwin first printed in book form in 1875 by John Murray.  Originally, the text appeared as essay in the 9th volume of the "Journal of the Linnean Society", therefore the first edition in book form is actually called the ‘second edition, revised.’  Illustrations were drawn by Charles Darwin’s son, George Darwin. Darwin: The Life of a Tormented Evolutionist is a biography of Charles Darwin by Adrian Desmond and James Moore.  It is considered one of three scholarly biographies of Darwin, along with "Charles Darwin: The Man and His Influence" (1996) by Peter J. Bowler and Janet Browne's two volume biography, "Charles Darwin: Voyaging" (1995) and "Charles Darwin: The Power of Place" (2002). More Letters of Charles Darwin, a sequel to "The Life and Letters of Charles Darwin" of 1887, was a book in two volumes, published in 1903, edited by Francis Darwin and A. C. Seward, containing as the title implies, additional publications of 782 letters from the correspondence of Charles Darwin. John van Wyhe is a historian of science, with a focus on Charles Darwin and Alfred Russel Wallace, at the National University of Singapore.  He holds some academic and research positions, ranging from founder and director of The Complete Works of Charles Darwin Online, Scientific Associate, The Natural History Museum (London), a Fellow of the Linnean Society and a Member of the British Society for the History of Science.  He has given more than 50 public lectures on Darwin in more than a dozen countries.  He lectures and broadcasts on Darwin, evolution, science and religion and the history of science around world.  He also wrote "The Darwin Experience", a biographical book about Charles Darwin. The Voyage of Charles Darwin was a 1978 BBC television serial depicting the life of Charles Darwin, focusing largely on his voyage on the HMS "Beagle".  The series encompasses his university days to the 1859 publication of his book "On the Origin of Species" and his death and is loosely based on Darwin's own letters, diaries, and journals, especially "The Voyage of the Beagle" and "The Autobiography of Charles Darwin".  It starred Malcolm Stoddard as Darwin and Andrew Burt as Captain Robert FitzRoy. The Voyage of the Beagle is the title most commonly given to the book written by Charles Darwin and published in 1839 as his Journal and Remarks, bringing him considerable fame and respect.  This was the third volume of "The Narrative of the Voyages of H.M. Ships Adventure and Beagle", the other volumes of which were written or edited by the commanders of the ships.  "Journal and Remarks" covers Darwin's part in the second survey expedition of the ship HMS "Beagle".  Due to the popularity of Darwin's account, the publisher reissued it later in 1839 as Darwin's Journal of Researches, and the revised second edition published in 1845 used this title.  A republication of the book in 1905 introduced the title "The Voyage of the "Beagle"", by which it is now best known.
