I've seen many times how a person born in one place, goes to another country for a long time, and then they start looking more like the people there, but I never found out how it works. This report claims that second generation Japanese, born in the US are taller and heavier than those living in their native lands (there had been no intermingling of races).

  • To what extent do the genetic/environmental factors control human morphology ?
  • What factors apart from the diet can bring about such morphological differences ?

I think this needs to be referenced as an actual phenomenon in order to be answerable. – Rory M Apr 22 '13 at 12:00
I'm searching for any relevant research documents right now, and I only find blog posts of people wondering the same thing, but the answers are only based on guesses. – user1306322 Apr 22 '13 at 12:24
@user1306322: added a reference for you.. co-incidentally someone told me about this just few hours ago :) – WYSIWYG Apr 22 '13 at 14:06
I think that particular instance probably reflects dietary changes more than anything else. – dd3 Apr 22 '13 at 14:45
