Yeah I've found that we greatly over exaggerated the moors. We also under estimate the European too much.
May there have been some cacs living in caves and crawling on all fours in certain parts of Europe, sure. But that doesn't account for North East and North West Europe, nor Russia.
There's always at least two classes of whatever group, and there were cacs in oarts of Europe and Asia who didn't need to be taught to wipe their ass' and they came thru and crushed the buildings for the entire world.
