The hidden history in our DNA - Part 2 - Travel and Culture
Our genomes are more than just an instruction manual for our bodies. They are maps, diaries, history books and medical records of our and our ancestor's lives...if you know how to read them. In the second part of BBC Inside Science's special, series, Adam Rutherford, UCL geneticist Lucy van Dorp and other scientists discover how travel and even culture of our ancestors can be decoded in our DNA today.
