We are the only species on earth that cooks its food - and we are also the cleverest species on the planet. The question is: do we cook because we're clever and imaginative, or are we clever and imaginative because our ancestors discovered cooking? Horizon examines the evidence that our ancestors' changing diet and their mastery of fire prompted anatomical and neurological changes that resulted in taking us out of the trees and into the kitchen.

When the Second World War ended, the people of liberated Europe celebrated their freedom from Nazi tyranny. Their years of suffering had ended, but for millions of Germans, the end of the conflict opened a new and terrible chapter. They suffered the appalling violence meted out to the defeated, especially to those ethnic Germans who had lived peacefully for centuries in neighbouring countries". Savage Peace uses rare and unseen archive film, the documentary tells a harrowing story of vengeance against German civilians, which mirrored some of the worst cruelty of the Nazi occupiers during the years of war. The Savage Peace includes the unique testimony of eyewitnesses and victims, who recall the horrors with searing clarity, their memories undimmed 70 years after the events took place. This a story that has, until now, been untold amidst the justified celebration of an end to an unspeakable tyranny. But as the writer George Orwell said, the treatment of the defeated Germans was a terrible crime that has gone unpunished.

Among the ranks of the Wehrmacht there was limited opposition to Hitler. Most officers initially felt enthusiastic about the prospect of war and were grateful to Hitler whose war-mongering had furthered their personal careers. Furthermore all soldiers had to make an oath of allegiance to the Führer and, up until the very end, there were many who felt unable to break this pledge. There were, however, some officers who opposed Hitler. For some it was on moral grounds and for others because they thought that his military tactics would lose them the war. There were plots against Hitler and attempted coups, the best known being the July bomb plot led by Claus von Stauffenberg. Some soldiers refused to bear arms and were shot, others deserted, others still carried out quiet acts of sabotage and subversion. By and large, however, the Wehrmacht carried out the orders Hitler issued, even if it involved perpetrating acts of atrocity.
