Wikipedia has a known bias of having mostly the historical events present that western world has written down. This map seems almost balanced, how come it used a better or at least perhaps fairer datasource?
Sigh, because certain civilizations wrote things down more than others. Also, some environments don't lend themselves to preserving things, others are. These will naturally create biases because if you are studying somewhere wet, almost nothing not made of stone will survive, even and especially things that are written upon. In the desert, things will be preserved for centuries, including things made of clay, leather or paper.
