The Siamese fighting fish is so aggressive it will fight its own reflection until it is exhausted. Recent research shows that the fighting behaviour varies and depends on the personality of the fish! Male kangaroos were once pitted against humans in the boxing ring, with the most impressive male kangaroos being solid blocks of muscle with a kick that can kill. Why do they fight and what skills must a winner have?

The second episode of Andrew Marr's exploration of Darwin explores the impact of Darwin’s ideas on society and politics. Darwin’s first port of call on the Beagle was Salvador in Brazil – then a major port for the international slave trade. His experience there confirmed his enlightenment views of liberty and progress and his hatred of slavery. But his theory of evolution that began to take root on that epic voyage would describe a world of conflict, ruthless competition and struggle. It would be taken up and abused by some of the most reactionary movements of the late-19th and 20th centuries. The phrase “survival of the fittest” would help propel Darwin’s theory as a scientific justification for eugenics, enforced sterilisation and genocide. But after the Second World War, Darwin’s theory finds redemption in the United Nations statement on race which confirms Darwin’s long-held view that all humans are members of the same race and deserving of equal treatment. This is further reinforced in the extraordinary work of a small Jewish community in New York who used DNA testing and a voluntary and anonymous form of selective breeding to eliminate a debilitating disease from the Jewish community. DNA testing is the final frontier of Darwin’s Dangerous idea. But the lessons from history suggest that the new choices we face about what to do with the knowledge Darwin has given us when combined with genetics and DNA testing remains a major social and political challenge.

Elephant seals are the first animals to return to the beaches of the subantarctic islands in spring, forming large breeding colonies, where the males fight fierce battles to gain and retain permanent access to a large number of females. They mate with the females as soon as they are receptive again. Millions of Macaroni Penguins form huge colonies on the islands to breed.
