The fact that we can retrieve a genome from a 40,000-year-old finger bone and learn that it belonged to a previously unknown group of humans—that’s the kind of thing that keeps me up at night, in a good way.

Analyse

Pääbo’s statement refers to the 2010 sequencing of a genome from a **41,000-year-old finger bone** found in Denisova Cave (Siberia), which revealed the **Denisovans**—a distinct hominin group unknown prior to genetic analysis. The discovery was published in *Nature* (Reich et al., 2010) and widely covered (e.g., *NYT*, *Science*), with Pääbo repeatedly expressing awe in interviews (e.g., *New Yorker* 2017, *Nobel Prize lectures*). The timeline, methodological rigor, and his personal reflections are consistently corroborated by primary sources and third-party reporting.

Achtergrond

Denisovans were identified solely through ancient DNA (aDNA) due to sparse fossil evidence, marking a paradigm shift in anthropology. Pääbo’s team pioneered techniques to extract and sequence degraded DNA from tiny samples, enabling discoveries like Neanderthal-Denisovan interbreeding. His work earned the **2022 Nobel Prize in Physiology or Medicine** for 'paleogenomics.'

Samenvatting verdict

Svante Pääbo’s 2010 discovery of Denisovans from a ~40,000-year-old finger bone is a well-documented, groundbreaking achievement in paleogenetics, and his quoted excitement aligns with public and scientific records.
