Origins of Us tells the story of our species, homo sapiens. In every one of our bodies is the evidence of how we evolved away from our ape cousins to become the adaptable, successful species we are today. Anatomist and physical anthropologist Dr Alice Roberts reveals the key adaptations in our body that has contributed to our extra-ordinary success. Far from being inevitable, the evolution of our species is a product of pure chance. And with each anatomical advantage comes a cost, which many of us are still paying today. Bad backs, painful childbirth, impacted wisdom teeth are all a by-product of our evolutionary success. This is a journey through your own body, 6 million years and 300 000 generations of our family, from a tree dwelling ape in the forests of Africa, to you and the six billion other humans on Earth today.

Épisode 1 - Bones
17 octobre 2011
In the first episode, Dr Alice Roberts looks at how our skeleton reveals our incredible evolutionary journey. Trekking through the forests of our ancient ancestors, she goes to meet the apes who still live there today - chimpanzees. In six million years we have become very different, and what kick-started this can be found in an extraordinary fossil - Sahelanthropus. A single hole where the spine was attached suggests that our ancestors started the journey to being human by standing upright. We take it for granted, but standing up and walking is surprisingly complex - each step involves the co-ordination of over 200 muscles. Charting the major advances from Australopithecus to Homo erectus and beyond, Alice tells the epic story of human evolution through our body today. New research has uncovered clues in our ankles, waists and necks that show how our ancestors were forced to survive on the open plain - by walking and running for their lives. From the neck down we have inherited the body of our ancestor Homo erectus, who lived on the plains of Africa nearly two million years ago. Finally Alice looks at probably the most important advance in our evolutionary story. A fortuitous by-product of standing up was freeing up our hands. With pressure-sensitive gloves, she demonstrates how the tiniest of anatomical tweaks to our thumbs and little fingers transformed hands that evolved to grasp branches into ones that could use tools. And with our dexterous hands, our species, Homo sapiens, would change the world. Erratum: The fossil cast at 08:40 in the Bones show is in fact KNM-ER 1813 rather than TM266-01-60-1. However, the information stated about the fossil Sahelanthropus is correct.
Épisode 2 - Guts
24 octobre 2011
In this second episode Dr Alice Roberts charts how our ancestors’ hunt for food has driven the way we look and behave today – from the shape of our face, to the way we see and even the way we attract the opposite sex.
Épisode 3 - Brains
31 octobre 2011
In the final episode Dr Alice Roberts explores how our species, homo sapiens, developed our large brain; and asks why we are the only one of our kind left on the planet today?
