Scientists Compared Sicilian DNA to Northern Italian DNA They Are Not the Same People

Sicilians are not Italians. And before you grab your keyboard to write in the comments that this is a provocation, let me explain. Because I'm not the one saying it. Genetics says it. Studies published in the most prestigious scientific journals in the world say it. An analysis endorsed by nature itself says it. Sicilians are not Italians, genetically speaking. They are something different. They are a unique mixture in the world. A combination that has been forming for 3,000 years on an island in the middle of the Mediterranean. An island that has been Greek, that has been Carthaginian, that has been Arab, that has been Norman, that has been Spanish, and only in the last 160 years Italian. And all those cultural layers have left deep marks on the DNA of its people. So deep that, according to the most rigorous genetic studies published to date, modern Sicilians are genetically more different from Northern Italians than Northern Italians are from Germans themselves. Yes, you heard that right. A Sicilian from Palermo and a Milanese from Northern Italy, who share a passport, language, flag, and national anthem, are genetically more distant from each other than a Milanese and a German from Munich. I'm not making that up. It has been measured. It has been calculated. It has been published. And when you understand why, when you understand the stories of the civilizations that passed through that island and left their mark on its inhabitants, when you understand the genetic magnitude of what Sicily is, then you will also understand why Sicilian culture, Sicilian food, Sicilian physical features, Sicilian surnames, and the Sicilian dialect are so profoundly different from the rest of Italy. Because genetically, they are not the same. They are what is now considered one of the most genetically mixed peoples in all of Europe. A kind of Mediterranean melting pot where, for 3,000 years, layer after layer of different peoples has been deposited, and where every layer is still alive today in the genome of every modern Sicilian.

And if by the end of the video you discover something about Sicilians that you didn't know, let me know in the comments. To understand why Sicilians are genetically different from Northern Italians, first you have to understand the geography. Sicily is the largest island in the Mediterranean. It is located right in the center of that sea, barely 160 kilometers from the African coast, just a few kilometers from the southern tip of the Italian peninsula, on the natural route between Europe, Africa, and the Middle East. That geographical position has made Sicily, for thousands of years, the crossroads of the Mediterranean. Everyone passed through there. Everyone conquered the island. Everyone left something behind. And all of that has remained biologically imprinted on its inhabitants. The genetic history of Sicily begins with its first inhabitants. Three prehistoric peoples lived on the island before any other civilization arrived. The Saccani the oldest, who occupied the center and west of the island. The Sacculi, who arrived from the Italian peninsula around 1,200 years before Christ, gave the island its name and settled in the east. And the Elimi in the far west, who according to tradition had come from Anatolia, possibly from defeated Troy. Those three peoples already made Sicily a genetically diverse island, even before the arrival of the great Mediterranean empires. But the massive genetic transformation began with the Greeks. Starting in the 8th century before Christ, the Greeks began colonizing the eastern and southern coast of Sicily. They founded cities such as Syracuse, Catania, Agrigento, Selinunte, and Messina. They created a Greek territory so large, so cultured, and so important that it was called Magna Graecia, Great Greece. Sicily became for several centuries one of the most Greek regions in the world, with Greek temples, Greek theaters, Greek philosophers, Greek dialects. And that massive colonization was not only cultural, it was also biological. Hundreds of thousands of Greeks crossed the Ionian Sea and settled permanently on the island. They had children. Those children had more children. And 2,700 years later, Greek DNA still dominates an important part of the modern Sicilian genome. How much exactly? Here comes the concrete figure. A fundamental study published in Nature in the European Journal of Human Genetics in 2009 analyzed the paternal lines, the Y-chromosome, of Sicilian men. The authors of the study, based on samples taken in multiple regions of Sicily, calculated with scientific precision that 37% of modern Sicilian paternal lineages are of Greek origin. 37%. Almost 4 out of every 10 Sicilian men carry in their Y-chromosome the direct genetic trace of those Greek colonists who arrived on the island 2,700 years ago. That is an enormous amount. To give you an idea, in northern mainland Italy, Greek influence on the Y-chromosome is practically non-existent. 3%. 5% at most. In Sicily, it is 37%. An enormous difference. And here it already begins to become clear why Sicilians are genetically different from the rest of Italians. But the genetic history of Sicily does not stop there. After the Greeks came the Romans. And although the Romans conquered the island in the 3rd century before Christ during the Punic Wars, they left a relatively smaller genetic mark. For one simple reason. The Romans did not massively colonize Sicily. They administered it, yes. They built infrastructure, yes. But they did not send waves of Roman colonists to settle on the island. The inhabitants remained mainly the descendants of the Greeks, the Sicani, the Siculi, and the Elimi. Roman DNA left a moderate mark, but not a transformative one. After the Romans came the next great change. The Arabs. In the year 827 after Christ, the Aghlabids, an Arab Berber group from North Africa, began the conquest of Sicily. The conquest lasted 70 years. And for the next 200 years, until the year 1061, Sicily was an Islamic emirate. Palermo became one of the most cultured, wealthiest, and most cosmopolitan cities in the Mediterranean. An Arab city in the heart of Italy. Mosques, minarets, bazaars, gardens. Everything built by the Muslim conquerors. And as with all the other conquerors, settlers also came. Arab and Berber families who settled permanently on the island, especially in the west, where they founded towns such as Masera del Vallo, which still today has a population with identifiable Arab descent. The genetic study from the European Journal of Human Genetics also measured the Arab and North African influence in modern Sicilian DNA. The Arab North African contribution to the Sicilian Y-chromosome is approximately 6%. It may seem small in absolute terms, but there are areas where it is much higher. In Southern Sicily, in the Ragusa region, that figure reaches 10%. And in the west, where the main Arab settlements were located, it reaches up to 14% in some families. For comparison, Arab North African influence in the DNA of Northern Italy is practically zero, less than 1% in most cases. Another massive genetic difference between Sicilians and Northern Italians. But the story does not end with the Arabs. In 1061, the Normans, direct descendants of the Vikings, who had settled in Northern France centuries earlier, conquered Sicily under the leadership of Roger de Hauteville. And here something fascinating happens. Those Normans, technically blonde-haired, blue-eyed Vikings according to the descriptions of the time, conquered a Mediterranean island populated by descendants of Greeks, Arabs, and North Africans. And they stayed. They founded a kingdom, the Norman Kingdom of Sicily. They brought with them nobles, soldiers, settlers, entire families. And they also left their genetic mark, a Nordic mark, a Viking mark, in the very center of the Mediterranean. Genetic studies identify the Norman mark in Sicily mainly through haplogroup B1, a marker characteristic of the peoples of Northern Europe, especially Scandinavia and the British Isles. In Northwestern Sicily, in the area around Palermo, especially in towns such as Cacamo, the frequency of this Nordic haplogroup comes to represent almost one-third of male genetic samples, 30%. An absolutely surprising figure for a Mediterranean island. Across the island as a whole, the Norman contribution to the Sicilian Y chromosome is estimated at between 8 and 20%. And that, on an island in Southern Italy, is genetically extraordinary. Modern Sicilians with Viking blood, Sicilians whose DNA partly matches the Northern Scottish DNA we have already seen in other videos on the channel. And as if all this were not enough, after the Normans came the Aragonese, the Castilians, and the French under the Angevin. All of them left some genetic mark, especially the migrations from the Iberian Peninsula during the 14th, 15th, and 16th centuries. When we add all these layers together what we get is an absolutely unique Sicilian genome. A mixture of Greeks, Arabs, Normans, Spaniards, on top of a prehistoric Mediterranean substrate, with continental Italian elements as well, with the presence of Albanian populations who took refuge in the 15th century, the Arberetia who still speak their Albanian language in some Sicilian villages, with Jewish traces from the Sephardic communities that lived on the island for centuries before their expulsion in 1492. Now let's compare this with Northern Italians. The inhabitants of Lombardy, Piedmont, Veneto, and Emilia-Romagna are genetically very different. Their DNA reflects Celtic influences from before Rome, Roman influences, Lombard influences, Frankish influences, Alpine influences. They have very little Greek DNA, almost no Arab DNA, practically no North African DNA. They share more DNA with the Swiss, the Austrians, the Southern Germans, and the French than with Sicilians themselves. And this is what modern genetic studies have demonstrated emphatically. The genetic distance between a Sicilian from Palermo and a Milanese from Lombardy is greater than the genetic distance between that Milanese and a German from Munich. Read that sentence again, because it is the key to this entire video. The genetic distance between a Sicilian and a Northern Italian is greater than the genetic distance between that Northern Italian and a German. That means that when a modern Sicilian and a modern Milanese meet and say, we are Italians, culturally it may be true. Linguistically, it may be true. Politically, it may be true. But biologically, no. Biologically, they are two different peoples with radically different evolutionary histories. Italian unification, which only took place in 1861, barely 160 years ago, did not change that genetic reality. Italy, as a political nation, is very young. But the genetic differences between its regions have been accumulating for 3,000 years. There is an absolutely fundamental study published in Scientific Reports, a journal from The Nature Group, in 2017. It was led by Alessandro Raviane, Ana Olivieri, and a team from the University of Pavia, in collaboration with scientists from Bologna and Cagliari. They analyzed the whole genome, not just the Y chromosome, of 560 people belonging to 23 different populations from southern Italy, Sicily, Greece, and the Balkans. And what they found was striking. Modern Sicilians form their own genetic cluster, their own well-defined group in the European genetic space. A group that is much closer to Greeks, Cypriots, and Southern Italians. When they created principal component graphs, those maps where populations are placed according to their genetic similarity, Sicilians appear grouped with the peoples of the eastern Mediterranean, not with their compatriots from the north. For the authors of the study, this reflects the deep legacy of the ancient Greek period, and later Mediterranean migrations. It is a mark that does not disappear, that does not become diluted in 160 years of political unification. That remains there, generation after generation, in every Sicilian child who is born and in every commercial DNA test that a Sicilian American takes in California or New York and looks at with surprise. This explains something that many Italian Americans descended from Sicilians have always felt but have rarely been able to articulate. When the grandson of a Sicilian immigrant who arrived in the United States at the beginning of the 20th century looks at old photographs of his grandfather, he sees features that are not exactly the features of the typical Italian shown in Hollywood movies. He sees darker skin, he sees deeper eyes, he sees noses, chins, facial shapes that have something of ancient Greece, something Arab, something more broadly Mediterranean. And when that same grandson takes a modern DNA test and gets 5% North African, 3% Caucasus, 7% Greek, and does not understand why, being Italian, he has that mixture, the answer is this, his family is Sicilian. And Sicilians are genetically a deep and unique mixture of the Mediterranean. They are not the standard version of the Italian that popular culture has sold for decades. There is another detail from the study that is fascinating and connects with previous videos on the channel. The authors found that within Sicily itself there is also enormous genetic heterogeneity. The east of the island, where the Greek colonists were mainly located, is genetically more Greek. The west, where the Phoenicians and Arabs dominated, is genetically more North African and Levantine. The northwest, where the Normans settled, has that Nordic mark we already mentioned. The Arboretia, the descendants of Albanian refugees, maintain their own identifiable Albanian genetic signature. And this means that not even within Sicily are Sicilians a uniform people. They are several peoples within the same people, several genomes within the same collective genome, several histories intertwined on a single island. When you ask a modern Sicilian what he feels, what identity he has, the answer is usually different from that of a northern Italian. A Milanese would say, I am Italian. A Sicilian would say, I am Sicilian. The difference is subtle but profound. And that identity difference, that feeling of being something distinct, is not only cultural. It has a biological basis. It has a genetic basis. It is written in their chromosomes, in their mitochondrial DNA, in their haplogroups. Sicilians feel that they are different because biologically they are. And science, after decades of studies, has confirmed what they always knew intuitively. There is one more fact I want to share with you because it is absolutely brutal. When researchers compared Sicilians with all European and Mediterranean populations in the principal component graphs of the scientific report study, they found that the population genetically closest to Sicilians was not northern Italians, not even continental southern Italians from Calabria or Apulia, although the distance with them is relatively smaller. The population genetically closest to Sicilians was Cypriots, the inhabitants of the island of Cyprus, at the opposite end of the Mediterranean, more than 2,000 kilometers away, speaking a completely different language, with a totally different political history. Sicilians and This gives you an idea of how deeply the Mediterranean has shaped the biological identity of Sicilians. And there is still more. The researchers also compared Sicilian DNA with modern Greek DNA, and they found something curious. Modern Sicilians share more DNA with modern Greeks from the Peloponnese, especially from eastern and central Greece, than with northern Italians. The Greek mark from 2,700 years ago, planted by the colonists of Magna Graecia, remains the dominant genetic component in modern Sicilian identity. Those Greek colonists did not leave. Their descendants never went away. They mixed with all the later peoples, yes, but the Greek base persisted and still persists. There are modern Sicilians who, if they took a DNA test comparing themselves only with ancient populations, would come out as 40% or more direct descendants of the ancient classical Greeks. And that would not be said by their surnames, nor their accent, nor their passport. Their blood says it. This has profound cultural implications. When a modern Sicilian cooks pasta with sardines and raisins, he is cooking a dish that combines ancient Greek ingredients with medieval Arab techniques. When a Sicilian uses words from his dialect such as Zibibo, Gebea, or Damusu, he is using words of Arab origin that have survived for 1,200 years. When a Sicilian looks at the architecture of the Palatine Chapel of Palermo, with its Greek Byzantine mosaics, its Arab arches, and its Norman structure all in one building, he is seeing the materialization in stone of his own genetic identity. Culture and genetics in Sicily go hand in hand. Both are products of the same historical process. And that is why both are so profoundly different from the rest of Italy. Because both come from 3,000 years of Mediterranean mixture, not from the Italian unification of the 19th century. To finish this journey, let me tell you one more fact that puts everything into perspective. The island of Sicily has approximately 5 million inhabitants today. Throughout the 20th century, another 4 or 5 million descendants of Sicilians emigrated to the United States, Argentina, Australia, Germany, and other European countries. The Sicilian diaspora is one of the most widespread in the world. And every one of those descendants, when they take a modern DNA test, finds this extraordinary mixture in their genome. A mixture that is, quite simply, unique in Europe. A mixture that tells the story of 3,000 years of migrations, conquests, cultural exchanges, and human mixing on a single island. A mixture that makes Sicilians something different. Something of their own. Something that does not fully fit into any rigid category. There is a fascinating phenomenon that has been observed in recent years with the popularization of commercial DNA tests such as Ancestry, 23, and Me, or MyHeritage. When 3rd or 4th generation Sicilian descendants, born in the United States or in other countries, take these tests out of curiosity, the results that appear on screen often surprise them. They expected a very high percentage of simply Italian. What they receive is an explosion of categories. Southern Italian, yes, but also Greek, also North African, also Caucasus, also Levantine, also Iberian, also Northern European. Many Sicilian Americans upload videos to YouTube reacting to these results, surprised, sometimes even unsettled. And all of that simply reflects the genetic reality of Sicily. It is not a test error. It is not an anomaly. It is exactly what 3,000 years of Mediterranean history have left in every Sicilian. A deep, multi-layered, fascinating mixture. A mixture that no other European people has in that specific magnitude and combination. When someone says that a Sicilian and a Northern Italian are the same, they are not necessarily telling a lie culturally, but they are ignoring 3,000 years of genetics. They are erasing, with a single stroke, the traces of the Greeks of Syracuse, the Arabs of Palermo, the Normans of Cacamo, the Phoenicians of Masara del Vallo, the Aragonese, the Aberration Albanians, the Cypriots, lost in time. They are reducing one of the most fascinating human mixtures that has ever existed in European history to a political label. And that, scientifically, does not hold up. The science is clear. Sicilians are not the same as Northern Italians. They are something unique. Something profoundly Mediterranean. Something that only Sicily, with its position at the center of that historic sea, could have produced. When a modern Sicilian looks out toward the Mediterranean Sea, when he sees the coast of Tunisia so close to the south, when he thinks about the Greek culture that filled his island thousands of years ago, when he hears in his own dialect words of Arab, Norman, Greek, and Spanish origin all mixed into the same sentence, what he is experiencing is not only culture. It is biology. It is his own genome speaking to him. Every cell in his body is a small museum of 3,000 years of Mediterranean history. Every chromosome is the trace of a different people who passed through his island and stayed. And that genetic mosaic, that biological kaleidoscope, is what defines Sicily. It is what makes it unique. It is what makes it simply not the same thing as the rest of Italy. Sicilians are Sicilians. And that, according to modern genetics, is its own category. Distinct, fascinating, and unique. 3,000 years of the Mediterranean written in the DNA of 5 million people living today on an island. And in just as many millions spread throughout the world, are the living legacy of one of the most complex and most beautiful human stories that exists. When you understand that, when you understand that Sicily is not just another region of Italy, but a people in itself, with its own deep genetic history, then you can appreciate why Sicilian culture is so different, so powerful, so persistent. It is not just culture. It is DNA. It is blood. It is 3,000 years of Mediterranean history still running, generation after generation, in every child of the island.
