Svante Pääbo is a Swedish geneticist who pioneered the field of paleogenetics, the study of ancient DNA. He is best known for leading the international effort that successfully sequenced the genome of Neanderthals and for the subsequent discovery of a previously unknown human relative, the Denisovan. His groundbreaking work, which revealed that early modern humans interbred with these now-extinct hominins, earned him the Nobel Prize in Physiology or Medicine in 2022. Pääbo is a director at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.

Early life and education

Svante Pääbo was born in Stockholm to Estonian chemist Karin Pääbo and Swedish biochemist Sune Bergström, who later won the Nobel Prize in Physiology or Medicine in 1982. He developed an early fascination with ancient Egyptian culture and archaeology. Pääbo began his university studies in history of science and Egyptology at Uppsala University before switching to medicine and later pursuing a PhD in molecular biology. His doctoral research, conducted under the supervision of Per Elias at Uppsala University, involved studying the Ebola virus protein and marked his initial foray into genetic techniques.

Career and research

After completing his PhD, Pääbo became a postdoctoral fellow at the Institute for Molecular Biology II in Zürich, Switzerland, and later at the University of California, Berkeley. In 1990, he was appointed as a professor at the University of Munich, where he began his seminal work on extracting DNA from ancient biological specimens. A major breakthrough came with his team's successful sequencing of mitochondrial DNA from a Neanderthal bone, published in the journal *Cell* in 1997. In 1997, he was recruited to help found the new Max Planck Institute for Evolutionary Anthropology in Leipzig, where he established and continues to lead the Department of Evolutionary Genetics.

Neanderthal genome project

Pääbo spearheaded the ambitious Neanderthal genome project, an international collaboration aiming to sequence the entire nuclear genome of our closest extinct relatives. The project faced immense technical challenges, including contamination with modern human DNA and the degraded state of ancient genetic material. His team developed stringent clean-room protocols and novel computational methods to overcome these hurdles. The first draft sequence of the Neanderthal genome, published in 2010 in the journal *Science*, provided definitive genetic evidence that Neanderthals interbred with ancestors of modern non-African populations, leaving a legacy of 1-2% Neanderthal DNA in people of Eurasian descent today.

Denisovan discovery

During the Neanderthal genome project, Pääbo's team analyzed a small finger bone fragment discovered in the Denisova Cave in the Altai Mountains of Siberia. The mitochondrial DNA sequence, published in 2010, was distinct from both modern humans and Neanderthals, indicating the existence of a previously unknown hominin group, named the Denisovan. Subsequent sequencing of the full Denisovan genome revealed that this group also interbred with modern humans, particularly with the ancestors of present-day populations in Melanesia and Southeast Asia. This discovery, alongside the Neanderthal findings, fundamentally reshaped the understanding of human evolution and migration.

Awards and honors

For his transformative contributions to science, Svante Pääbo has received numerous prestigious awards. These include the Gottfried Wilhelm Leibniz Prize (1992), the Louis-Jeantet Prize for Medicine (2005), the Kistler Prize (2009), and the Gruber Prize in Genetics (2013). He was elected a member of the Royal Swedish Academy of Sciences, the National Academy of Sciences of the United States, and a foreign member of the Royal Society. In 2022, he was awarded the Nobel Prize in Physiology or Medicine for his discoveries concerning the genomes of extinct hominins and human evolution.

Personal life

Svante Pääbo is married to Linda Vigilant, a primatologist and geneticist who is also a researcher at the Max Planck Institute for Evolutionary Anthropology. He has previously described himself as bisexual. Pääbo is an avid reader of science fiction and enjoys the music of Richard Wagner. He became a citizen of Germany in 2016 and continues his research and mentorship in Leipzig.
