Do guys from Portugal look like guys from Brazil?

Um, I guess it depends on them, you really can't tell. Brw, Brazilians are more than just the descendants of Portuguese settlers and migrants, they may have Italian, German, Japanese, black, Indian, Arab and many more ancestors, whereas most of the Portuguese are simply European who may descend from Iberians, Romans (well, roman soldiers mostly from current Hungary in fact), Celts, Visigoths, Moors, Vikings too and more.
