Today we say goodbye to the Pre-Pottery Neolithic B with a look at the collapse of the PPNB world system. Of course, as it is still up in the air as to whether we ever actually HAD a PPNB world system, we can also have a look at whether or not we actually have a PPNB collapse. Have a listen and tell me what you think. Does the PPNB collapse, or not? If you have any questions or comments you can email me at [email protected] or reach me on the website at prehistorypodast.com.
