I’m stuck on a History question and need an explanation.

History relies upon a multitude of other disciplines, which makes it exciting and dynamic. The possibilities for cross-disciplinary work are huge. The importance of archeology for historians is huge. Where would we be without the work of archeologists in Egypt, Mesopotamia, or the prehistoric cave art ? I found this fun TED talk on the importance of archeology and new methods of doing it that I thought some of you might enjoy. IF you listen to it and then post a 150 word reply, I’ll deposit 2 extra credit points into your Treasure of Merit.
