Scientists map Leonardo da Vinci family tree for DNA project

Researchers have traced Leonardo da Vinci's family across 21 generations, identifying 15 living male descendants for genetic analysis. The Leonardo DNA Project aims to reconstruct the Renaissance genius's genetic profile using Y chromosome matches. Excavations at a family tomb in Vinci, Italy, are underway to recover ancient remains for comparison.

A new book, 'Genìa Da Vinci. Genealogy and Genetics for Leonardo's DNA,' details three decades of research by Alessandro Vezzosi and Agnese Sabato of the Leonardo Da Vinci Heritage Association in Vinci. Supported by the Municipality of Vinci, the study reconstructs a family tree from 1331, covering more than 400 individuals. It identifies 15 living male descendants linked through the paternal line to Leonardo's father and half-brother, Domenico Benedetto. DNA tests on six of these descendants, conducted by David Caramelli of the University of Florence and Elena Pilli, confirm matching Y chromosome segments, verifying a continuous male lineage over at least 15 generations. Caramelli noted, 'Further detailed analyses are necessary to determine whether the DNA extracted is sufficiently preserved.' Archaeological digs at the Da Vinci family tomb in the Church of Santa Croce in Vinci have uncovered bone fragments, including one radiocarbon-dated specimen from a male consistent with Leonardo's relatives. Anthropologists Alessandro Riga and Luca Bachechi are analyzing these for Y chromosome matches with living descendants. The Leonardo DNA Project, launched in 2016 and coordinated from The Rockefeller University in New York, involves institutions like the J. Craig Venter Institute and the University of Florence. Project director Jesse H. Ausubel said, 'Even a tiny fingerprint on a page could contain cells to sequence.' Vezzosi added, 'Through the recovery of Leonardo's DNA, we hope to understand the biological roots of his extraordinary visual acuity, creativity, and possibly even aspects of his health and causes of death.' The effort could enable DNA analysis from Leonardo's manuscripts or artworks, potentially revealing traits like left-handedness or health predispositions.

Ancient sheep DNA offers new clues to how a Bronze Age plague spread across Eurasia

Researchers analyzing ancient DNA say they have detected the plague bacterium Yersinia pestis in the remains of a domesticated sheep from Arkaim, a Bronze Age settlement in the southern Ural region of present-day Russia. The team reports this is the first known identification of a Bronze Age plague lineage in a nonhuman host from that period, a finding that could help explain how an early, pre-flea-adapted form of plague traveled widely across Eurasia.

Researchers have analyzed mitochondrial DNA from eight Neanderthal teeth found in Stajnia Cave in Poland, reconstructing the genetic profile of a small group that lived there around 100,000 years ago. The study, published in Current Biology, marks the first such multi-individual genetic picture from a single site north of the Carpathians. The findings show genetic links to Neanderthals across Europe and the Caucasus.

An international team of researchers has used ancient DNA to diagnose a rare genetic growth disorder in two individuals buried together over 12,000 years ago in southern Italy. The analysis reveals that the younger person suffered from acromesomelic dysplasia, while her likely mother had a milder form of short stature. This discovery highlights the deep history of rare genetic conditions in human populations.

A new book by bioethicist Daphne O. Martschenko and sociologist Sam Trejo explores the implications of polygenic scores in genetic testing, highlighting potential inequalities and myths surrounding genetics. Through their 'adversarial collaboration,' the authors debate whether such research can promote equity or entrench social divides. They call for stricter regulation to ensure responsible use.

Scientists have found genetic evidence that modern humans reached New Guinea and Australia around 60,000 years ago, backing the long chronology over more recent estimates. The international team, led by researchers at the University of Huddersfield and the University of Southampton, analyzed nearly 2,500 mitochondrial DNA genomes from Aboriginal Australians, New Guineans, and Southeast Asian populations. Their work suggests early migrants used at least two routes through Southeast Asia.
