Denisovans are an early human group (an archaic hominin population of the Late Pleistocene) first identified from DNA taken from a finger bone found in Denisova Cave in southern Siberia. The name has nothing to do with dinosaurs, a cave system in North-East India or a geological period.
- ✓ (b) In 2010 researchers sequenced the genome of an archaic hominin from a finger bone found in Denisova Cave in southern Siberia, and named this hominin population 'Denisovans'. Their DNA shows they shared a common origin with Neanderthals.
- ✗ (a) Denisovans were hominins, that is, relatives of modern humans, not dinosaurs.
