Now im 3/4th asleep and the last 1/4th is running on nodoz and monster so hopefully i make sense.
Now that said how about lower (1/2 or less) gravity with bigger people taking much longer strides, as time has passed humans have gotten bigger, for example in biblical times the average hight for males was 4'8" to 5'2" depending on which paper you read and what area of the world with some ADULT male remains as short as 4', today the average hight is roughly 5'10" or more with 6'0-6'2" not that unusual.
Now.assume this trend keeps up, 2k years was a gain of 8 inches at least 1 foot 10 inches at most, that would mean in 3500 years you would have humans at a minimum of 7 foot a max of 8'7"
This is not taking into account things like generations on a low G worlds making them taller, mutations, bio engineering, bio weapons, cyro sleep ect.
But its a start, to someone 9 foot tall on a low G world 5km would be far shorter and easier to cross then someone 6 foot tall in 1 G, just a thought, im going to bed now
