Melvyn Bragg and his guests discuss the work of Alfred Russel Wallace, a pioneer of evolutionary theory. Born in 1823, Wallace travelled extensively, charting the distribution of animal species throughout the world. This fieldwork in the Amazon and later the Malay Archipelago led him to formulate a theory of evolution through natural selection. In 1858 he sent the paper he wrote on the subject to Charles Darwin, who was spurred into the writing and publication of his own masterpiece On the Origin of Species. Wallace was also the founder of the science of biogeography and made important discoveries about the nature of animal coloration. But despite his visionary work, Wallace has been overshadowed by the greater fame of his contemporary Darwin.

Ice Ages

Jane Francis, Richard Corfield and Carrie Lear join Melvyn Bragg to discuss ice ages, periods when a reduction in the surface temperature of the Earth has resulted in ice sheets at the Poles. Although the term 'ice age' is commonly associated with prehistoric eras when much of northern Europe was covered in ice, we are in fact currently in an ice age which began up to 40 million years ago. Geological evidence indicates that there have been several in the Earth's history, although their precise cause is not known. Ice ages have had profound effects on the geography and biology of our planet.

Melvyn Bragg and his guests discuss the Putney Debates. For several weeks in late 1647, after the defeat of King Charles I in the first hostilities of the Civil War, representatives of the New Model Army and the radical Levellers met in a church in Putney to debate the future of England. There was much to discuss: who should be allowed to vote, civil liberties and religious freedom. The debates were inconclusive, but the ideas aired in Putney had a considerable influence on centuries of political thought.
