That wasn't the claim. You should read the reply chain but the point isn't about archaeology but our interpretation of civilization outside Rome and Greece. You wanted to know why these civilizations get that share of work...the reason why is that their thought was more relevant to us (again, most Europeans believed in Aristotelian science until humanism). And, again, these civilizations were more African than European...it is nothing to do with racism (which was the implication).
That wasn't the claim. I will explain, although you would do just as well to go back and read what I said more closely...again. The point is: many people who are perceived to be part of the European tradition (i.e. Rome/Greece) are not Europeans. So when someone says: Europe has got a disproportionate share of work, these regions are ignored, their civilizations are ignored...this is wrong. Most of these civilizations were mutli-culutural/multi-national, and included Africa (the other big contributor would be the Middle East). Again, attempting to read the current political view onto the past. And the point about Augustine is that he was African, the point about academics who say things like: we are too Euro-centric is that they define Europe in a way that makes no historical sense (unsurprisingly, as they are usually arguing about things in the present, not anything related to history...the concept of Europe itself is not something with a clear historical meaning).
