Denisovans were first identified in 2010 from DNA extracted from an ancient finger bone found in Denisova Cave, Siberia.

Notes on verification

Confirmed by original peer-reviewed Nature papers (Krause et al. 2010; Reich et al. 2010) and multiple independent secondary sources including Britannica and Wikipedia. Minor nuance that the bone was excavated in 2008 but genetically identified/announced in 2010 does not contradict the claim.
