| Fate of Ancient Canaanites Seen in DNA Analysis: They SurvivedBy NICHOLAS ST. FLEUR JULY 27, 2017 Remnants from an ancient Canaanite found in the Sidon excavation site.

The team then compared the ancient DNA with the genomes of 99 living people from Lebanon that the group had sequenced. It found that the modern Lebanese people shared about 93 percent of their ancestry with the Bronze Age Sidon samples. The Sidon excavation site in Lebanon.

Their writings may have been kept on papyrus, which did not stand the test of time as clay did. What is known about the Canaanites is that they lived and traded along the eastern coast of the present-day Mediterranean, a region that was known as the Levant.“What we see is that since the Bronze Age, this ancestry, or the genetics of the people there, didn’t change much,” Dr. Haber said. “It changed a little, but it didn’t change much and that is what surprised me.”At first the team was not sure if it would be able to retrieve DNA from the ancient skeletons, which were recovered from the hot and humid excavation site within the last 19 years. Dr. Haber had chosen more than two dozen bones from the site that looked promising and had them investigated for genetic material. It turned out that only five contained ancient DNA. All of those came from the petrous part of the temporal bone, which is the tough part of the skull behind the ear, from five different individuals. Ancient DNA recovered from bones in the excavation site was sequenced for a new study.CreditClaude Doumet-Serhal/Sidon ExcavationAfter extracting that DNA, the team members compared it with a database that contained genetic information from hundreds of human populations. They then further compared their results with the genomes of the modern-day Lebanese population sample, which revealed what happened to the ancient Canaanite population.“Genetics has the power to answer questions that historical records or archaeology are not able to answer,” Dr. Haber said.He said researchers thought that migrations, conquests and the intermixing of Eurasian people — like the Assyrians, Persians or Macedonians — with the Canaanites 3,800 to 2,200 years ago might have contributed to the slight genetic changes seen in modern Lebanese populations. Still, the Lebanese retain most of their ancestral DNA from the Canaanites.“It confirms the continuity of occupation and rooted tradition we have seen on-site, which was occupied from the 4th millennium B.C. right to the Crusader period,” Claude Doumet-Serhal, an archaeologist and director of the Sidon Excavation who is a co-author on the paper, said in an email.She said that the archaeologists had found about 160 burials to date at their excavation site, which is in the heart of modern Sidon. They include graves and burials where a person was placed in a large jar, and they date to between 1900 and 1550 B.C. The genetic results further support the archaeological findings.“We were delighted by the findings,” Dr. Doumet-Serhal said. “We are looking at the Canaanite society through 160 burials and at the same time uncovering a common past for all the people of Lebanon, whatever religion they belong to.” |
