Humans are everywhere. How did we get from the savannahs of Africa across to the most northern reaches of Alaska and Greenland, to the outbacks of Australia and the islands of the Pacific millennia ago? How did we master fire, figure out how to craft tools and survive the Ice Ages?

In this episode Dan is joined by Professor Chris Stringer, Research Leader in Human Evolution at London's Natural History Museum, to talk about how Homo Sapiens managed to outlive other human cousins like Neanderthals and Denisovans and cross oceans s hape landscapes and one day, build cities and space shuttles.

Produced by James Hickmann, Mariana Des Forges and edited by Tim Arstall.

For thousands of years, ancient cuneiform - the script of the ancient Mesopotamians was lost to time, until being dramatically rediscovered in the 19th century by an adventurous group of unlikely Victorians. A dashing archaeologist, an officer turned diplomat and a reclusive clergyman raced to decipher it and unlock the secrets of long-lost empires.

Joining us is Joshua Hammer, a former war correspondent and author of 'The Mesopotamian Riddle'.

Following the defeat of Nazi Germany in 1945 some of its most egregious war criminals sought to escape justice by fleeing Europe, most famously to South America. The escape routes they used, established by Nazi sympathisers, came to be known as 'ratlines'. The escaping Nazis had helped from an unexpected source; senior figures within the Catholic Church.

The story of SS officer Walter Rauff exemplifies how these networks operated and the subsequent lives of the escapees. Rauff was responsible for the deaths of hundreds of thousands of people during the Second World War and was a key perpetrator of the Holocaust. After escaping to Chile, he would eventually come to work for the brutal Chilean dictator Augusto Pinochet. There he would go on to inflict further miseries on the Chilean people. Rauff was never put on trial, but is it possible to obtain a different kind of justice for his numerous crimes?

Philippe Sands, a renowned British-French lawyer and author, joins Dan to provide insights from his book '38 Londres Street: On Impunity, Pinochet in England and a Nazi in Patagonia', which explores Rauff's life and actions and the involvement of the Catholic Church.

Produced & edited by Dougal Patmore.
