Why are ethnics always either short or tall?

[Napoleon1800]

All the ethnics I've seen are either 5'9 and below or 6'0 and above. Never in the average height range.

5'9 is actually tall for ethnic also if 5'9 is short for your standarts then 6'0 is not tall either

5'9-5'11 is average height range in the west
