In this free course, Evolution through natural selection, we describe the theory of evolution by natural selection as proposed by Charles Darwin in his book, first published in 1859, On the Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Life. We will look at natural selection as Darwin did, taking inheritance for granted, but ignoring the mechanisms underlying it.

Can Darwin's theory of evolution be applied to cultural institutions like the family? If so, how can it help us to understand how family structures have evolved? If not, what are the limitations of a Darwinian approach? In this album, Ruth Mace, Professor of Evolutionary Biology at UCL in London, reveals how she uses a Darwinian approach to study diverse human populations. In particular, she focuses her discussion on family size, exploring how Darwinian concepts such as evolutionary trade-offs can help explain why modern families are getting smaller and smaller.

Just how controversial was Charles Darwin? Was he a reluctant revolutionary? And how did he reconcile his religious convictions with his scientific values? When Darwin's theories were first published in the nineteenth century, he initially felt that the whole scientific establishment was against him. It took many years for Darwin to finally pluck up the courage to reveal his revolutionary theories and he only did so when a fellow scientist seemed to be about publish something remarkably, and coincidentally, very similar. This album puts Charles Darwin into context and explores the complex moral environment in which he worked, and in particular the perceived clash between evolutionary theory and traditional creationist beliefs. Jim Moore, Professor of the History of Science at The Open University, leads this exploration of Darwin and his times.

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.

Why are we still interested in Charles Darwin, 200 years after his birth? Are his theories still as relevant? And what celebrations are planned for his anniversary? This album provides a solid introduction to Charles Darwin's groundbreaking theory of evolution. The geneticist Steve Jones and the historian Fern Elsdon-Baker explain and comment on Darwin's theoretical approach, and explore how evolutionary theory is relevant to modern environmental concerns and recent developments in genetics. Fern Elsdon Baker introduces the Darwin Now project and discusses some of the events which are planned for 2009. But in the midst of the all the adulation, Steve Jones sounds a note of warning, musing if at some stage in the future, Darwin will be eclipsed by new theorists, with a very different approach to evolution.

The Galapagos Islands are famous for inspiring Charles Darwin to form his Theory of Evolution based on the biodiversity he'd observed there. This year marks the 150th anniversary of the publication of his "On the origin of species", and the unspoilt islands still fascinate researchers. Some of the plants and animals that live here are found nowhere else on Earth. Today that biodiversity is under threat from an increasing population, tourism and invasive non-native species. The video tracks on this album retraces Darwin's first steps on the Galapagos islands, looks at some of the species that fascinated him, and at how threats to the environment are being managed. It also follows the day-to-day research of two biological scientists - Beatrix Schramm, who tries to get a faecal sample from a Giant Tortoise to learn more about what triggers them to mate, and Martin Wikelski who studies marine iguanas and the problems they face as a result of their choice of food. In the audio track, Open University biologist David Robinson talks about his long relationship with the Galapagos Islands and explores some of the issues raised in the video tracks.

This album explores the science of waves. Five video tracks feature two pair trawling fishermen from the Cornish village of Looe. Their lives and livelihoods depend on gadgets like radio, GPS and radar. This album explores the physics behind this technology, gives a simple introduction to wavelengths and looks back to the discovery of electromagnetism and the invention of radio. To demonstrate just how vital waves are, the two captains turn off their modern communication tools and try traditional methods of keeping in touch. In addition, two bonus video tracks explore Newton's laws of motion and Einstein’s special theory of relativity, which give us our most basic insight into space and time. This material forms part of the course S207 The physical world.
