Genetic studies

A 2008 study led by Pierre Zalloua found that six subclades of Haplogroup J-M172 (J2)—thought to have originated between the Caucasus Mountains, Mesopotamia and the Levant —were of a "Phoenician signature" and present amongst the male populations of coastal Lebanon as well as the wider Levant (the "Phoenician Periphery"), followed by other areas of historic Phoenician settlement, spanning Cyprus through to Morocco. This deliberate sequential sampling was an attempt to develop a methodology to link the documented historical expansion of a population with a particular geographic genetic pattern or patterns. The researchers suggested that the proposed genetic signature stemmed from "a common source of related lineages rooted in Lebanon ". Another study in 2006 found evidence for the genetic persistence of Phoenicians in the Spanish island of Ibiza.

In 2016, the rare U5b2c1 maternal haplogroup was identified in the DNA of a 2,500-year-old male skeleton excavated from a Punic tomb in Tunisia. The lineage of this "Young Man of Byrsa" is believed to represent early gene flow from Iberia to the Maghreb.

According to a 2017 study published by the American Journal of Human Genetics, present-day Lebanese derive most of their ancestry from a Canaanite -related population, which therefore implies substantial genetic continuity in the Levant since at least the Bronze Age. More specifically, the research of geneticist Chris Tyler-Smith and his team at the Sanger Institute in Britain, who compared "sampled ancient DNA from five Canaanite people who lived 3,750 and 3,650 years ago" to modern people, revealed that 93 percent of the genetic ancestry of people in Lebanon came from the Canaanites (the other 7 percent was of a Eurasian steppe population).

One 2018 study of mitochondrial lineages in Sardinia concluded that the Phoenicians were "inclusive, multicultural and featured significant female mobility", with evidence of indigenous Sardinians integrating "peacefully and permanently" with Semitic Phoenician settlers. The study also found evidence suggesting that south Europeans may have likewise settled in the area of modern Lebanon.

In a 2020 study published in the American Journal of Human Genetics, researchers have shown that there is substantial genetic continuity in Lebanon since the Bronze Age interrupted by three significant admixture events during the Iron Age, Hellenistic, and Ottoman period. In particular, the Phoenicians can be modeled as a mixture of the local Bronze Age population (63%–88%) and a population coming from the North, related to ancient Anatolians or ancient South-Eastern Europeans (12%–37%). The results show that a Steppe-like ancestry, typically found in Europeans, appears in the region starting from the Iron Age.
