The Discovery: Genomic Insights into Extinct Hominins
Svante Pääbo, a Swedish geneticist, made groundbreaking advancements in paleogenomics, the study of ancient DNA. Using innovative methods, Pääbo successfully extracted and sequenced DNA from ancient bones, which had previously been thought impossible due to degradation over millennia.
Key Discoveries:
- Neanderthal Genome Sequencing (2010)
Pääbo’s team sequenced the Neanderthal genome, revealing their genetic relationship to modern humans. - Denisovan Discovery (2010)
Pääbo identified a previously unknown hominin group, the Denisovans, from DNA extracted from a finger bone found in Siberia. - Interbreeding Evidence
His research demonstrated that modern humans interbred with Neanderthals and Denisovans, leaving traces of their DNA in present-day populations. (Source)
