Denisovan DNA in ancient humans: DNA segments inherited from Denisovans were identified in over 100 ancient human genomes from across Eurasia.

Varying levels of Denisovan ancestry: The earliest East Asians carried higher Denisovan ancestry than later East Asians.

Different histories of contact with Denisovans in East Asia: While the ancestors of mainland East Asians met Denisovans multiple times, one lineage that contributed to present-day Japanese reached coastal East Asia with minimal contact with Denisovans, if any.
