10,000 years ago the last mammoths to walk the earth were trapped on Wrangel island, northern Siberia. New genetic insights reveals, how many were trapped, how their population grew and perhaps even how they became extinct. I chatted to geneticst Marianne Dehasque about her fascinating research into the dna of the last mammoths.

If you are at all interested in archaeology (and occasional paleontology), I cannot recommend Stefan Milo more.
