Swedish geneticist who founded the study of ancient human DNA and sequenced the Neanderthal genome.
See it on the Life map →What happened
Pääbo (born 1955) first extracted DNA from an Egyptian mummy in 1985. Ancient DNA is broken into tiny fragments and easily swamped by modern contamination, so he developed clean-room methods. His team read Neanderthal mitochondrial DNA in 1997 and, at the Max Planck Institute for Evolutionary Anthropology in Leipzig, a draft Neanderthal genome in 2010, showing that non-Africans carry some Neanderthal DNA. That year his group also identified the Denisovans from a finger bone. He won the 2022 Nobel Prize in Physiology or Medicine.
Why it matters
He created paleogenomics, which revealed that our ancestors interbred with other human groups whose genes still affect health today.
Discoveries and legacy
Landmark papers in Cell (1997) and Science (2010); his memoir Neanderthal Man (2014); the 2022 Nobel citation, for discoveries on 'the genomes of extinct hominins and human evolution'.
Still debated
How long and in what climates DNA can survive, and what many inherited Neanderthal and Denisovan gene variants actually do in us.

▸Svante Pääbo sequenced the genome of NeanderthalsWell established
The connection
Svante Pääbo spent decades learning to extract and read the damaged, contaminated DNA in old bones. His team first read Neanderthal mitochondrial DNA in 1997, then a draft of the full genome in 2010, revealing that people outside Africa carry Neanderthal DNA.
When and how
University of Munich (1997 sequence, from the original Neander Valley bones) and the Max Planck Institute for Evolutionary Anthropology, Leipzig (2010 draft genome); Nobel Prize in Physiology or Medicine, 2022.
The evidence
Results were confirmed by higher-quality genomes from Siberian and Croatian Neanderthals and by other labs; damage patterns and contamination checks show the DNA is genuinely ancient.
Debates and open questions
How much Neanderthal DNA natural selection purged, and what the surviving Neanderthal gene variants do for health and traits today, are active research questions.
▸Svante Pääbo identified from DNA DenisovansWell established
The connection
A finger bone from Denisova Cave in Siberia was too small to identify by shape. Pääbo's team extracted its DNA and found a lineage unlike modern humans or Neanderthals. A nuclear genome later in 2010 showed it was a sister group of Neanderthals, now called Denisovans, whose DNA survives in some living people.
When and how
Bone excavated in 2008 by Russian archaeologists; DNA work at the Max Planck Institute in Leipzig, led by Johannes Krause and Pääbo, published in Nature in March and December 2010.
The evidence
A high-quality genome followed in 2012, and Denisovan DNA has since been found in teeth and cave sediments, and ancient proteins have identified Denisovan fossils from Tibet and China.
Debates and open questions
How many Denisovan groups existed and what they looked like; the 2025 Harbin skull identification is helping, as the Denisovans entry describes.
▸Svante Pääbo proved Interbreeding with Neanderthals & DenisovansWell established
The connection
Svante Pääbo's lab developed ways to recover and read fragile, contaminated ancient DNA. In 2010 it published a draft Neanderthal genome showing that non-Africans share extra DNA with Neanderthals, proving interbreeding. The same year it identified the Denisovans from a finger bone's DNA. He won the 2022 Nobel Prize in Physiology or Medicine.
When and how
Max Planck Institute for Evolutionary Anthropology, Leipzig, Germany; both genomes published in 2010, with Richard E. Green, David Reich and many colleagues.
The evidence
Published in Science and Nature in 2010 and confirmed by many later high-quality genomes; the Nobel committee cited his discoveries on extinct hominins.
Debates and open questions
His 1997 Neanderthal mitochondrial DNA had suggested no mixing, a view nuclear genomes reversed. Open questions now involve DNA from cave sediments and still-unknown 'ghost' groups.
