I had seen TV-programs similar to the ones on this DVD before. Probably on NatGeoTV. But I thought Iain Stewart's account – a new face, as far as I am concerned – did a very good job of reviewing everything science has been able to find out so far, about continental drift and its history, that goes back to the time when the Earth had but one continent – that we've all agreed to call "Pangea". But Pangea split into several pieces, and over the centuries the pieces drifted apart, until the geography looked like it does today. But the continental drift continues, and millions of years from now, the Earth's map will look very different from what it does today.
In particular, I liked how Iain – from Scotland I presume – related the various phases of geological history to the evolution of plants and animals, and how we've became what we are and how we are, due to these various geological stages, that have all left their traces in our build, our faculties and our abilities. A great set of documentary programs, and a great update on the latest geological knowledge!
