The Forgotten Voyage: The Story of Alfred Russel Wallace

The Forgotten Voyage was the dramatised story of Alfred Russel Wallace, the 19th century naturalist who published the theory of evolution by natural selection together with Charles Darwin in 1858 - more than a year before Darwin's book "On the Origin of Species" was released.

This film was written by Elaine Morgan and directed by Peter Crawford. Actor Tim Preece played the part of Alfred Russel Wallace, the 19th Century naturalist. It was Wallace's eight year voyage of discovery to the East Indies in search of wildlife that prompted Darwin to publish his revolutionary theory on the evolution of life by Natural Selection.

Darwin’s Darkest Hour

Darwin's Darkest Hour tells the remarkable story behind the unveiling of the most influential scientific theory of all time, Charles Darwin's theory of evolution by natural selection. Darwin spent years refining his ideas and penning what he called his "big book." Yet, daunted by looming conflict with the orthodox religious values of his day, he resisted publishing–until a letter from naturalist Alfred Wallace forced his hand. In 1858, Darwin learned that Wallace was ready to publish ideas very similar to his own. In a sickened panic, Darwin grasped his dilemma: To delay publishing any longer would be to condemn his greatest work to obscurity–the brilliant argument he had pieced together with clues from his voyage on the Beagle, his adventures in the Andes, the bizarre fossils of Patagonia, the finches and giant tortoises of the Galapagos, as well as the British countryside. But to come forward with his ideas risked the fury of the Church and perhaps a rift with his own devoted wife, Emma, who was a devout Christian.

What Darwin Never Knew

Earth teems with a staggering variety of animals, including 9,000 kinds of birds, 28,000 types of fish, and more than 350,000 species of beetles. What explains this explosion of living creatures—1.4 million different species discovered so far, with perhaps another 50 million to go? The source of life's endless forms was a profound mystery until Charles Darwin brought forth his revolutionary idea of natural selection. But Darwin's radical insights raised as many questions as they answered. What actually drives evolution and turns one species into another? To what degree do different animals rely on the same genetic toolkit? And how did we evolve? (from pbs.org)

What Darwin Didn’t Know

Documentary which tells the story of evolution theory since Darwin postulated it in 1859 in 'On the Origin of Species'.

The theory of evolution by natural selection is now scientific orthodoxy, but when it was unveiled it caused a storm of controversy, from fellow scientists as well as religious people. They criticised it for being short on evidence and long on assertion and Darwin, being the honest scientist that he was, agreed with them. He knew that his theory was riddled with 'difficulties', but he entrusted future generations to complete his work and prove the essential truth of his vision, which is what scientists have been doing for the past 150 years.

Evolutionary biologist Professor Armand Marie Leroi charts the scientific endeavour that brought about the triumphant renaissance of Darwin's theory. He argues that, with the new science of evolutionary developmental biology (evo devo), it may be possible to take that theory to a new level - to do more than explain what has evolved in the past, and start to predict what might evolve in the future.
