Ancestor:  Denisova 8; lived between 134,400 - 103,600 BCE.

And Yes! it's true; You Shared A Common Ancestor 705,000 BCE..

You and Denisova 8 share a common paternal line ancestor who lived around this time.

Every modern human shares this connection with Denisova 8.

Denisova 8 was an adult Denisovan man who lived between 134,400 and 103,600 BCE in the Altai Mountains region of southern Siberia, Russia. This region of Central Asia was quite temperate, and thus, Denisova 8 and his kin would have been well-adapted to cold living. Only his molar tooth (pictured) was ever recovered. It was unearthed in Denisova Cave from where the species Homo denisova got its name.

Not much is known about Denisovans, except we have learned that some humans today still carry small remnants of autosomal Denisovan DNA. Denisovan DNA occurs in highest frequency (~5%) among people of Papuan and Aboriginal Australian ancestry. This suggests that humans encountered Denisovans in South or Central Asia upon exiting Africa and mated with them before first migrating across Indonesia to Australia and Papua New Guinea some 50,000 years ago.

Deniosova 8 lived over 100,000 years ago, making it the oldest Y-chromosome DNA ever extracted and sequenced from a hominin species. Given its distinctiveness from human and Neanderthal genomes, ISOGG (International Society of Genetic Genealogy) assigned it the haplogroup name A0000 in 2019. A0000 diverged from Neanderthal and human Y chromosomes some 700,000 years ago.
