Part of the issue is Asia, Africa and so on do less indigenous studies. Some of that may be due to less interest in who the previous occupiers were. That said, there are ample maps showing migrations and settlement patterns through history of Europe and the Middle East in particular usually in rough slices of time but aren't represented here. The black sea area and the Middle East had lots and lots of turnover as there were movements and conquests after conquests and movements.

One reason not to include them on the map is that would illustrate the nature of waves and conquests thought-out the ages until relatively recently when territories congealed. however, this would undermine the notion that the Americas had little turnover of land control and that there was less intertribal warfare and that extra continental conquests are different.
