You knows how to distinguish races by seeing images? that is, to differentiate between a German white and a Mediterranean white, between a French and a Spanish and an Italian, between a Russian and a German? Evidently a slight resemblance between Hitler and Merkel is seen, but the things in which they resemble are Germanic features and that can be found in a fairly considerable percentage of the population. It is my opinion. There are videos about it on youtube. Even so, the first time I heard that theory I was very impressed, because I had not had other factors in mind.
