Haplogroup I and height

[Podlachian]

Here states, that original Europeans were short. Higher height came to Europe from Asia.

"Height is one of the defining features of people from northern Europe, but it seems they owe their towering stature to an ancient group of nomads from central Asia's steppes. Researchers studying DNA from Stone Age human remains have, for the first time, been able to track some of the key genetic changes that shaped modern Europeans. In particular, they found that people from northern Europe owe their height to Bronze-age populations from the Eurasian steppes who migrated into the region. Southern Europeans, on the other hand, owe their short stature to Neolithic hunter gatherers and later copper-age farmers living in Iberia."

I don't think there is a correlation between haplogroup I and tall people. About 45% of Sardinians have I haplogroup and we are not very tall.

Interesting theory, though I don't think haplogroup alone determines height. For example my Dad is 6', I am 5' 7.5" and my bro is 5' 5.5". While our dad is tall, in a Western context my bro and I are considered short despite having the same haplogroup.
