**Max Planck Institute press coverage / phys.org** — Researcher quotes: Slon (“the first time we have found a direct, first-generation offspring”) and Pääbo (“I initially thought they must have screwed up in the lab”). ZooMS screening context.
**The Science Breaker (plain-language summary of Slon et al. 2018)** — Confirmed: protein analysis used to identify hominin bone; 2,000 fragments screened; nuclear DNA showing Neanderthal and Denisovan variants in equal proportions; model comparison showing first-generation hybrid fitted data best; mother more closely related to Croatian (Vindija) Neanderthal ~55,000 years ago than to Denisova Cave Neanderthal ~120,000 years ago; father carried Neanderthal DNA from approximately 10,000–15,000 years earlier (the primary study places this at 300–600 generations); mixing happened at least twice.
**Mental Floss — Denisovans facts** — Background on Denisovan discovery (2010 finger bone, Russian archaeologists Michael Shunkov and Anatoly Derevianko, DNA identification by Pääbo’s team); geographic range from Siberia through Southeast Asia; Denisovan DNA in modern humans including 3–6% in some Southeast Asian and Oceanic groups; EPAS1 gene in Tibetans; Neanderthals and Denisovans descending from *Homo heidelbergensis*; divergence ~400,000–500,000 years ago; Denisovan extinction ~30,000 years ago.
**zmescience.com — Denisova Cave chronology** — Denisovans in cave ~287,000–55,000 years ago (or at least 195,000 years ago per a second study); Neanderthals ~193,000–97,000 years ago; early Upper Palaeolithic bone points and pierced teeth 43,000–49,000 years ago; optical and radiocarbon dating methods; Robin Dennell quote on cold and warm period occupation.
