According to the organisation, the prize was given to Pbo for his discoveries concerning the genomes of extinct hominins and human evolution.
The prize was announced on Monday by the assembly at the institute. Pbo's research into ancient genes and the establishment of a new scientific discipline, paleogenomics, has been seminal in the quest to discover more about humankind's origins.
