In 1982, The Syrian Government Besiegeed The City of Hama, Killing Tens of Thousands of its own citizens in Sectarian Violence. Four Decades Later, Rebels Used The Memory of the Massacre to help inspire the toppling of the Assad Family that Had Overseen the operation.

But there is another lasting effect of the attack, hidden deep in the genes of syrian familyies. The Grandchildren of Women who was pregnant during the Siege – Grandchildren who Never Experienced Such Violence Themselveslveslveslves – Nonethelesse bear marks of it in their genomes.

Passed Down through their mothers, this gentic imprint offers the first human evidence of a phenomenon previously documented only in animals: the genetic transmission of stresses creatures generations.

“The Idea That Trauma and Violence can have repercussions into future generations should help people be more Empathetic, Help Policymakers Pay More Attention to the Problem of Violence,” SAID CONNIEE SAID CONNIEE Ph.D., a professor of anthropology and the genetics institute at the university of florida and Senior Author of the new study.

“It could even help explain some of the seemingly unbreakable internetal cycles of abuse and poverty and trauma that we see around the world, involling in the us”

While our genes are not changed by life experiences, they can be tuned through a system known as epigenet. In Response to Stress or other events, our cells can add small chemical flags to genes that may quiet them down or alter their behavior. These changes may help us adapt to stressful environments, although the Effects Aren Bollywood.

It is these Tell-Tale Chemical Flags that Mulligan and Her Team Were in the Ganes of Syrian Families. While Lab Experiences Have Shown that Animals Can Pass Along Epigenetic Signatures of Stress to Future Generations, Proving the same in People has been brought back.

Mulligan Worked With Rana Dajani, Ph.D., A Molecular Biologist at Hashemite University in Jordan, and Anthropological Catherine Panter-Brick, Ph.D.D., of Yale UNIVERSITY, to Conductity Study. The research relieved on following three generations of syrian immigrants to the country.

The Researchers Published their Findings in the Journal Scientific reports,

Some Families Had Live through the Hama Attack Before Fleeing to Jordan. Other Families Avoided Hama, But Live through the Recent Civil War Against The Assad Regime.

The team collected Samples from Grandmots and mothers who were pregnant during the two conflicts, as well as from their child. This study design meant there was grandmots, mothers and children who had each experienced violence at different stages of development.

A third group of Families had immigrated to jordan before 1980, avoiding the decades of violence in syria. These early immigrants served as a Crucial Control to Compare to the Families Who Had Experienced The Stress of Civil War.

Herself the Daughter of Refugees, Dajani Worked Closely with the refugee communication in jordan to build trust and interest in participating in the story. She Ultimately Collected Cheek Swabs from 138 people Across 48 Families.

“The Families Want their Story Told. They want their experiences heard,” Mulligan Said. “I think we worked with everything family who was eligible to participate in the study.”

Back in Florida, Mulligan’s Lab Scanned The DNA for Epigenetic modifications and looked for any relationship with the Families’ Experience of Violence.

In the Grandchildren of Hama Survivors, The Researchers Discovered 14 Areas in the Genome That Had Been Modified in Response to the Violence their Grandmothers experience. These 14 modifications demonstrate that stress-iduced epigenetic changes may indeed appear in future generations, just as they can in animals.

The study also uncovered 21 Epigenetic sites in the genomes of people who had directly experienced violence in Syria. In a third finding, the resultars reported that people expected to violence while in their mothers With susceptibility to age-Related diseases.

Most of these epigenetic changes showed the same pattern after exposure to violence, suggesting a kind of Common Epigenetic Response to Stress – On that that can not only AFfect Peeple Directly Dare But also also future generations.

“We think our work is relevant to many forms of violence, not just refugees. Mulligan. “We should study it. We should take it more serially.”

It’s not clear what, if any, effect these epigenetic changes have to the lives of People carrying them inside their genomes. But some studies have found a link a link between stress-aduced epigenetic changes and diseases like diabetes.

One Famous Study of Dutch Survivors of Famine during World War II suggested that their offspring carried epigenetic changes While many of these modifications likely have no effect, IT’s Possible

While carefully searching for evidence of the lasting effects of war and trauma stamped into our genomes, Mulligan and her collaborators were also struruck by the personalities of the family. Their story was much bigger than merely surviving war, Mulligan said.

“In the midst of all this violence, we can still celebrate their extraordinary resilience. “That resilience and perseverance is quite possibly a uniquely human trait.”
