Darwin and Inheritance - for iPod/iPhone The Open University How are genetic traits handed down through generations? How did you inherit your grandfather's red hair whilst your parents are both black-haired? Even Charles Darwin himself never really understood the causes behind this. This album traces the development of our understanding of the laws of inheritance. The tracks on this album, drawn from an Open University programme first broadcast in 1998, explore the discoveries of scientists such as the botanist Mendel, and the chemist Friedrich Miescher who first identified DNA, and see how they come together with Darwin's theory of evolution to form the concepts which lie at the heart of modern genetics. Contributors include Richard Dawkins, Colin Tudge, John Maynard Smith, Steven Rose and Steve Jones. Publishing The Origin of Species - for iPod/iPhone The Open University John Murray VII tells the fascinating story of how his ancestor, John Murray III, was offered the manuscript of Charles Darwin's The Origin of Species. Drawing upon original letters, photographs, family stories and the help of a set of live pigeons, he gives a unique insight in to the early history of this epoch-making book, telling how early readers advised John Murray against publishing it and revealing the small but crucial revisions that Darwin made to subsequent editions of the book. The tracks on this album were produced by The Open University in collaboration with the British Council. They form part of Darwin Now, a global initiative celebrating the life and work of Charles Darwin and the impact his ideas about evolution continue to have on today’s world. © British Council 2009. Darwin and Evolution - for iPad/Mac/PC The Open University 2009 marks the 200th anniversary of the birth of Charles Darwin and the 150th anniversary of the publication of On The Origin Of Species. This album introduces Darwin's great revelation: that species change and adapt according to their environment. Apparently diverse specimens and fossils reveal surprising results, such as the common ancestry of the hippopotamus and the dolphin, whose evolutionary paths diverged when their habitats changed. Research on sparrows show how particular characteristics are linked to success at surviving in the wild, and the selective breeding of dogs for aesthetic purposes shows how humans can influence the evolution of other species.
