Swedish scientist and paleogeneticist Svante Paabo, whose efforts to crack the genomes of extinct creatures led to breakthroughs in the study of human evolution, won the 2022 Nobel Prize in Physiology or Medicine for his discoveries on Monday.
The prize, arguably among the most prestigious in the scientific world, is awarded by the Nobel Assembly of Sweden's Karolinska Institute and is worth 10 million Swedish crowns ($900,357).
It is the first of this year's batch of prizes.
"He was overwhelmed, he was speechless. Very happy," said Thomas Perlmann, secretary for the Nobel Committee for Physiology or Medicine, who called Paabo with the news.
"He asked if he could tell anyone and asked if he could tell his wife and I said that was OK. He was incredibly thrilled about this award," Perlmann said.
Paabo, son of the Nobel Prize-winning biochemist Sune Bergström, has been credited with transforming the study of human origins after developing approaches to allow for the examination of DNA sequences from archaeological and paleontological remains.
His key achievements include sequencing an entire Neanderthal genome to reveal the link between extinct people and modern humans.
He also brought to light the existence of a previously unknown human species called the Denisovans, from a 40,000-year-old fragment of a finger bone discovered in Siberia.
Created in the will of Swedish dynamite inventor and wealthy oil baron Alfred Nobel, the prizes for achievements in science, literature and peace have been awarded since 1901, though the economics prize is a later addition.
The COVID-19 pandemic has placed medical research at center stage with many expecting that the development of the vaccines that have allowed the world to regain some sense of normality may eventually be rewarded.
Still, it typically takes many years for any given research to be honored, with the committees charged with picking the winners looking to determine its full value with some certainty amongst what is always a packed field of contenders.
This year's festivities should in any case mark the return of the Nobel banquet in Stockholm after a two-year hiatus due to the pandemic, an event redolent of old-world pomp and glamour after years of social distancing.
Last year's medicine prize went to Americans David Julius and Ardem Patapoutian for the discovery of receptors in the human skin that sense temperature and touch, converting the physical impact into nerve impulses.
Past winners in the field include a string of famous researchers, notably Alexander Fleming, who shared the 1945 prize for the discovery of penicillin, and Robert Koch, who won already in 1905 for his investigations of tuberculosis.
