"There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved." - from Charles Darwin's The Origin of Species From a review. "Darwin's idea explains the production of differing species through natural selection. Darwin did little to explain evolution, or the change, of species, but this book fully outlines how the mechanism of selection would make sure such random changes would produce complex organisms. The mechanism Darwin proposes is at once so simple and seems so obvious with hindsight. It is something evident to any dog breeder--that traits can be selected and passed on to different generations--and Darwin even draws upon knowledge of artificial selection in birds and dogs to bolster his claims. Ultimately, however, the evidence for evolution by natural selection lies not in a vague analogy to artificial selection, but in the predictions Darwin's theory made and fulfilled. Darwin's expectation of biological similarity in ancestors and descendants is fulfilled by simply looking at exterior features or even bone structures. He also notes that his theory thoroughly predicts and explains the existence of rudimentary features like teeth in whale embryos and flightless wings in birds. The fact that island species correspond most with similar species on the nearest continent, instead of in distant lands, shows that these species are descended from them and changed after migrating to a separate environment. Darwin also showed how his theory explained the difficulties with classifying species, because evolution thoroughly broke down the distinction of species as pure and distinct."

YOU ARE LOOKING AT A TRIBUTE TO THE GREAT PHYSICIST, POLYMATH, RENAISSANCE MAN, RICHARD P. FEYNMAN. IT FEATURES A PHOTOMANIPULATED FACE OF THE MAN WITH THE COLOURFUL LOGO "TUVA OR BUST" WRITTEN ABOVE. IT WAS A FAVOURED MOTTO USED BY FEYNMAN. HOPE YOU LIKE AND WILL CONSIDER CHECKING OUT MY OTHER DESIGNS. I TAKE REQUESTS TOO! HERE IS A TRUNCATED DEFINITION OF "TUVA OR BUST" FROM THE NET: Tuva or Bust! (1991) is a book by Ralph Leighton about the author and his friend Richard Feynman's attempt to travel to Tuva. The introduction explains how Feynman challenged Leighton, at the time a high school math teacher, "Whatever happened to Tannu Tuva (the Tuvan People's Republic)?" Since Feynman had a reputation as a prankster and had proven himself entirely capable of inventing a fictional country name to confound friends, Leighton assumed it was made up. But the country existed, and the pair became fascinated with this hard-to-reach destination, at the geographic center of Asia, which had become a republic in the Soviet Union. They made it a goal to travel there, which, for Americans in the late 1970s and early 1980s, was extremely difficult. In many ways, the attempt to travel to Tuva is an allegory for Feynman's perpetual curiosity to discover new things, and how he inspired his friends, admirers and protégés to do the same. During their decade-long quest to travel to Tuva, Feynman was suffering from cancer, and died shortly before the visas finally arrived; this book describes "Richard Feynman's last adventure". The book describes the difficulties and various attempts Leighton and Feynman made to obtain permission to travel to Tuva. It also describes the culture, language and history of the place. Included with some editions of the book is a small plastic turntable record of Tuvan throat singing. Feynman never managed to get to Tuva. Instead of him, the trip was realized by his daughter Michelle. Michelle Feynman travelled to Tuva on June 8, 2009.
