A very interesting documentary (about 6 hours long) is "how art made (built?) the world" it may be available to borrow from your local library.
A+++ would watch again.

you can get your DNA analysed under the National Geographic/IBM project for about £130 and it will tell you the route your ancestors took out of Africa. Try it, its fun and very educational.

In a related documentary, some 95,000 year old painting of a hash pipe and mushrooms, along with animals were discovered. The intresting part is the painting were made from a resin oil composit. O.o
