Summary:

After centuries of mystery, scientists are edging closer to uncovering Leonardo da Vinci’s biological secrets. A massive 30-year effort has mapped his family across 21 generations, identified living male descendants, and even confirmed shared DNA markers that stretch back to the Renaissance. Meanwhile, excavations at a family tomb in Vinci could provide ancient remains for comparison, raising the possibility of reconstructing Leonardo’s genetic profile.

For more than 500 years, Leonardo da Vinci has been admired as a brilliant artist, inventor, and thinker whose talents seemed far ahead of his time. Now, an ambitious international effort known as the Leonardo DNA Project is bringing scientists closer than ever to uncovering the biological roots of his genius.

A newly published book, "Genìa Da Vinci. Genealogy and Genetics for Leonardo's DNA," brings together three decades of research led by Alessandro Vezzosi and Agnese Sabato of the Leonardo Da Vinci Heritage Association in Vinci. Supported by the Municipality of Vinci, the work reconstructs an extensive family tree stretching back to 1331. It spans 21 generations and includes more than 400 individuals, creating the foundation for an unprecedented attempt to rebuild Leonardo's genetic profile.

By carefully studying archival records and historical documents, the researchers were able to map out previously unknown branches of Leonardo's family. In the process, they identified 15 living male descendants linked directly through the paternal line to Leonardo's father and his half-brother, Domenico Benedetto.

DNA Testing Links Living Descendants

This discovery opened the door for genetic analysis. David Caramelli, who coordinates the anthropological and molecular aspects of the Leonardo DNA Project and leads the Department of Biology at the University of Florence, worked with forensic anthropologist Elena Pilli to analyze DNA from six of these descendants.

The results showed that segments of the Y chromosome matched across the participants. Because this chromosome is passed from father to son with little change, the findings confirm a continuous male lineage within the Da Vinci family dating back at least 15 generations.

Ancient Tomb Could Hold Crucial Evidence

Researchers have also identified a Da Vinci family tomb at the Church of Santa Croce in Vinci. Archaeological excavations are currently underway in collaboration with the University of Florence. The site is believed to contain the remains of Leonardo's grandfather Antonio, his uncle Francesco, and several half-brothers, Antonio, Pandolfo, and Giovanni.

Anthropologists Alessandro Riga and Luca Bachechi have recovered bone fragments from the site, some of which have been radiocarbon dated. One specimen, consistent in age with Leonardo's relatives, has already undergone paleogenomic testing. Early analysis suggests the individual was male.

"Further detailed analyses are necessary to determine whether the DNA extracted is sufficiently preserved," says Caramelli, who is also President of the University Museum System. "Based on the results, we can proceed with analysis of Y chromosome fragments for comparison with current descendants."

If the Y chromosome from these remains matches that of living descendants, it would strengthen historical records and family lineage reconstructions. It could also make it possible to analyze biological traces connected to Leonardo himself, including material left on manuscripts or artworks, potentially enabling scientists to reconstruct his DNA.

A Global Scientific Effort

The Leonardo da Vinci DNA Project began in 2016 and is coordinated from The Rockefeller University in New York. It brings together institutions including the J. Craig Venter Institute in California and the University of Florence, with support from foundations such as the Achelis and Bodman Foundation (New York) and the Richard Lounsbery Foundation (Washington, D.C.).

The project focuses on tracking the Y chromosome, which passes largely unchanged through generations of males.

"Our goal in reconstructing the Da Vinci family's lineage up to the present day, while also preserving and valuing the places connected to Leonardo, is to enable scientific research on his DNA," says Vezzosi. "Through the recovery of Leonardo's DNA, we hope to understand the biological roots of his extraordinary visual acuity, creativity, and possibly even aspect
