In today's episode of Lost Origins, Andrew and CK link up with season two veteran, Bruce Fenton. Fenton returns to the show to continue the conversation started last season by explaining his work regarding the migration patterns of ancient peoples. As outlined in his book, The Forgotten Exodus, the origins of our ancestors leave much to be discovered.

While archaic hominids have walked the Earth from around 5 million years ago, we now know that close to 750,000 years ago something extraordinary began to happen to the genome of these distant ancestors, changes which marked the beginning of a unique species, Homo sapiens - us. Modern humans are quite unlike their primate relatives, but what was it about our slow trek through a prehistoric world that left us the black sheep of the global ecosystem? What epic trials did our ancestors pass through? How did we become so reliant on our technologies? Where on Earth did the critical scenes in our story play out?

Bruce Fenton is a British multidisciplinary scientific researcher and media personality. He curates the popular paleoanthropology website AncientNews.net. Fenton graduated from Anglia Ruskin University with a Higher National Diploma in Information Systems.
