Israel/Palestine was the crossroads of the ancient world between Europe, Asia, and Egypt. That is one of the reasons it was so fought over and could not establish itself as a kingdom except when there was power vacuums in Babylon and Egypt, such as when the Kingdom of Saul, Jonathan, and David arose. . . and for a time flourished. However, that crossroads meant that the people intermarried with people from many cultures as they passed through. . . or were forced into different locals. Mitochondrial DNA studies show that some Jews are descended from European females in the distant past. . . and today approximately 35% of the Levantine Jews are of a genotype that are not the "swarthy, Jewish looking chap" type you are expecting, but can be tall, lanky and European in appearance. . . some with darker to lighter hair. Recall that the Greeks had ruled Egypt for some three and a half centuries.
A census of a first century Jewish cemetery in Jerusalem, conducted in the 1980s, found that male skeletons averaged 5' 8 3/8" tall. . . 1/8" shorter than the average height of men in the United States today. Their Roman male conquerers averaged 5' 5 1/2" tall. Given a normal height distribution, heights of Jewish men of over six feet was not unusual, just as it is in today's America, and in fact several such skeletons were counted in the cemetery. They were rarer in Rome.
However, I do tend to agree with you that the 2004 regression shows a lot of pious artistic license and made the boy a tad too angelic. (grin) I detect a slight (maybe more than slight) religious bent to the artist who programed the regression. . . and perhaps he/she put a little too much female into the mix?
