.... Never seen one start with the earliest point at the bottom and go up. Left to right is Massively more common than top to bottom though.

Egypt (and most of north Africa, for that matter) has, for most if not all of its history, had much interaction with the middle east and Mediterranean civilizations. On the other hand, aside from the occasional border skirmish with its neighbour to the imediate south, and probably some trade there, it had very little interaction with the rest of Africa. (Well, I have vague recollections of a comparatively brief period of someone from the south taking over for a bit. But the operative word is vague). Going by their infrastructure, they had more contact with India than they did with most of Africa. Sure, they're on the African Continent, but to call them an African civilization is so misleading as to be functionally false.

@Ledabot ... Dark ages are explicitly regional and indicate only that the records for that place in that time period have been lost, or were never made, which the chart represents quite well. Further, if you actually pay attention, the non-european cultures also experience major shifts not far to either side of the European ones. Given the need to put dividers in Somewhere, and that the European shifts are usually closest to the average points each time, the location of the dividers would be weirder anywhere else. As for the names of each age, they've been established for centuries at this point. You could follow the same rather dishonest logic as that responsible for the whole CE/BCE shift (which if you break it down is primarily a product of ignorance and bigotry rather than any sort of enlightenment or being of any practical benefit) but it really wouldn't achieve anything other than annoying people trying to find more information because no other source would use the new system created just for this chart. I mean, the most accurate change that didn't just make the whole thing objectively less useful for no gain would be to drop a big "dark ages" box or five over most of the Americas and Pacific sections and otherwise leave it as is, at least in English.
