Genetic detective work could snap the Greek link
By Elias Hazou
WHERE do you come from? Not in a trippy, philosophical sense, but rather, who are your ancestors? Knowledge of one’s past is often passed down by word of mouth, and sometimes if you’re lucky there are documents to look at. Tracing one’s lineage, in search perhaps of a famous ancestor or royalty, has become highly popular, and the Internet is full of sites promising to reproduce your family tree. Now science is joining the fray, supplementing stones-and-bones archaeology.
Conventional wisdom has it that we Cypriots are descended primarily from the ancient Greeks. That assumption, though still holding up, could now be challenged by DNA research into our genetic makeup.
It’s no secret of course that the many conquerors who passed through Cyprus - Franks, Venetians, Arabs and Turks - have left their genetic imprint on the island.
But now the Phoenicians, that long-lost civilisation of famous seafarers, have come into the picture, and in a big way.
Recent genetic research carried out in Lebanon and other locations around the Mediterranean basin has shown that one in 17 people in Cyprus may have a Phoenician direct male-line ancestor.
The project is the brainchild of Dr Pierre Zalloua and his research partner, National Geographic explorer Spencer Wells.
What has been discovered indicates that the genetic makeup of the Lebanese, especially those of the coastal areas, is Phoenician. Further, it was discovered that various percentages of the inhabitants of the islands of Malta, Sardinia, as well as parts of ancient Carthage in Tunisia, Gibraltar, Spain and the islands of the Aegean have Phoenician DNA running through their veins.
Zalloua and his team chose to work with the Y chromosome for this purpose, because its male specificity meant that it would have been carried by the predominantly male Phoenician traders.
The Y chromosome is passed from father to son only.
The reference of the genetic prototype for the Phoenician makeup is based on human remains discovered in Turkey, as well as a human jaw - perhaps up to 4,000 years old - found in a mountain cave at Raskifa, Lebanon.
Though the Y chromosome method has to date not been employed by Cypriot scientists to map out our ancestry, epidemiological studies have yielded some intriguing results.
The studies were initiated to answer the question why certain diseases that are common in central and northern Europe also occur in parts of Cyprus to a significant degree.
In doing so, they have inadvertently stumbled on a trail leading back to antiquity.
Constandinos Voskarides, Post-Doctorate Fellow with the Department of Biological Sciences, University of Cyprus, said the method could reveal a great deal about our past.
For example, cystic fibrosis - a hereditary disease affecting the mucus glands of the lungs, liver, pancreas, and intestines - is caused by a mutation on a certain gene. The disease is common in countries such as France, Germany and Russia.
Research into the disease in Cyprus has homed in on the village of Athienou, where a substantial percentage of the population carries the guilty gene. The evidence confirmed archeological evidence that the site was the location of a substantial settlement of the Franks.
The university is seeking funds to carry out research similar to that of the Genographic Project, sponsored by IBM and National Geographic, which explores early human migratory patterns using genetic markers submitted by thousands of individuals.
Voskarides told the Sunday Mail the results would be used to determine the prevalence of Arab, Turkish and Greek genetic markers on the Cypriot population. This is done by comparing the findings to an enormous DNA database already available.
Other uses would include exploring genetic differences between geographical regions, for example, between Nicosia and Paphos.
Past genetic studies, though on a limited scale, have suggested that Greek and Turkish Cypriots are genetically closer to each other than they are with their respective “mother countries”. Popular culture has added to this, with the argument that Greek and Turkish Cypriots “look a lot alike”.
But looks aren’t everything, says Voskarides.
“The scientific community certainly suspects that DNA affects a person’s physical traits, but to date we’ve been unable to isolate a specific gene for such-and-such attribute.
“Take pigmentation, which is governed by how much melanin there is in your skin. The old myth that humans are divided into three races - black, white and yellow - has collapsed. In fact, scientists will tell you there are about 1,000 different types of pigmentation.”
Depending on the outcome, this research could open a Pandora’s Box were it found that the Greek element is not as strong as once thought. No doubt certain circles would be embarrassed if the results were not the “right ones”.
Take neighbouring Lebanon, where Dr Zalloua’s findings have already caused a stir, as longstanding assumptions of Arab ancestry are now on shaky ground.
