Traces of Leonardo da Vinci's DNA May Have Been Discovered on a Red Chalk Drawing Called 'Holy Child'

Researchers from the Leonardo da Vinci DNA Project (LDVP) that by analyzing the drafting of Holy Child and different Renaissance artifacts, specified arsenic letters written by a da Vinci relative, they person recovered immoderate Y chromosome DNA sequences that look to beryllium to a familial radical of radical with communal ancestors successful Tuscany, wherever the genius and Renaissance maestro was calved successful 1452. The findings, archetypal reported successful Science, could beryllium the archetypal clip scientists person identified DNA from da Vinci himself.

The DNA

Historical artifacts tin accumulate DNA from the situation and perchance connection utile accusation astir the radical who created and handled them. Gathering that worldly connected specified precious objects without damaging oregon contaminating them, though, is simply a analyzable challenge. Today, decisions astir the authorship of a enactment beryllium connected adept opinion—for example, connected however a brushstroke was created.

The LDVP researchers truthful utilized an highly gentle swabbing method to effort to cod biologic material. They past extracted tiny amounts of DNA, which provided utile information. "We recovered heterogeneous mixtures of non-human DNA," states the survey published successful the preprint diary bioRxiv, “and, successful a subset of samples, sparse male-specific quality DNA signals.”

The da Vinci Clue

From the investigation the researchers concluded that they recovered the closest lucifer wrong the wide E1b1b lineage connected the Y chromosome (whose sections are passed connected astir unchanged from begetter to son) that is present commonly recovered successful confederate Europe, Africa, and parts of the Middle East. Some of the DNA, they say, whitethorn person travel from Leonardo da Vinci himself.

“Across aggregate autarkic swabs from Leonardo da Vinci-associated items, the obtained Y chromosome marker information suggested assignments wrong the broader E1b1/E1b1b clade,” the survey reads. The results besides bespeak mixed DNA contributions assocaited with the root materials, though, accordant with modern handling.

“Together, these information show the feasibility arsenic good arsenic limitations of combining metagenomics and quality DNA marker investigation for taste practice science," the insubstantial reads, "providing a baseline workflow for aboriginal conservation subject studies and hypothesis-driven investigations of provenance, authentication and handling history.”

Further Investigation

While the researches person demonstrated an innovative approach, they admit that they didn't travel backmost with conclusive evidence. Although the information suggest that the DNA could beryllium Leonardo da Vinci's, asserting that immoderate hint of DNA successful the artifacts really belongs to him is precise complpicated. “Establishing an unequivocal individuality ... is highly complex,” David Caramelli, an anthropologist astatine the University of Florence and LDVP member, told Science.

This is due to the fact that scientists cannot verify the familial sequences of the artifacts by comparing them with DNA known to person been taken from Leonardo da Vinci himself; determination are inactive nary confirmed samples. Moreover, da Vinci had nary known nonstop descendants, and his burial tract was breached successful the aboriginal 19th century. Encouraged by the archetypal hint astir da Vinci's DNA, LDVP scientists present anticipation to person the custodians of Leonardo's works and notebooks to let them further sampling that could lick the case.
