Leonardo da Vinci may have living descendants: genetic analyses have confirmed the presence of the Y chromosome in six Tuscan men, all of whom are patrilineally related to their father or to a half-brother of the Renaissance genius. Five of them, aged 40 to 90, currently live in Tuscany, but none in Vinci. One of the six has recently passed away. The discovery is a critical step in the process of recovering Leonardo's DNA, an objective that the Leonardo DNA Project, an international initiative established by Rockefeller University in New York thirty years ago, is seeking to achieve. The book Genìa Da Vinci, which was presented in Florence by researchers Alessandro Vezzosi and Agnese Sabato, provides the detailed information. The book, which was published by Pontecorboli with the patronage of the Municipality of Vinci and the support of the Richard Lounsbery Foundation, provides an updated family tree of the Da Vinci family, which spans 21 generations and includes more than 400 individuals, beginning in 1331. Genetic studies conducted by anthropologists David Caramelli and Elena Pilli confirmed the Y chromosome's continuity dating back at least to the 15th generation. The next stage will be to match these findings to the human remains of the Da Vinci family, which are now being excavated in the church of Santa Croce in Vinci.
