This is a question that wouldn't occur every day. Actually I thought of this while walking though the exhibits of the "King Tut" exhibition at the Field Museum in Chicago. Among the many artefacts, there was a statue that looked kind if strange – it was the head of Amarna Princess (note: I believe the name is misspelled on the official site). She had an abnormally prolonged head. As I am not too fond of Creationism, and Darwinism, I started thinking what could have caused this elongated skull? Did she have special powers, being it religious or of other kind. Or was her skull just artificially deformed, as found in some ancient cultures.
This prompted me to do a quick research, and I found some interesting stuff. Actually some ancient races with natural elongated skulls may have existed indeed. Starting from ancient pre-Incan South America to Babylon and pre-dynasty and early Egypt – when the Great Pyramid was built (~1000 years before the reign of Tutankamun). And there were other peoples who imitated them by artificially prolonging their skulls by head-binding infants for long periods of time. What was interesting was that the people with the prolonged skulls were usually priests or had other high-ranking positions. Interesting, huh?
I will not speculate what where these people could have come from. However, I found an entire long publication on www.biped.info regarding this matter, exploring scientific findings linking the so called dolichocephalous anomaly: “The Dolichocephaloids – Missing Race of Our Human Family” (http://www.biped.info/articles/missingrace.html)
Here are a couple of photos from the article:
