A road from Africa across Eurasia has revealed evidence of the extraordinary love between us modern humans and at least 4 ancient species of extinction.

New research by the Australian Ancient DNA Center at the University of Adelaide (Australia) redraws the map of a historical path that our Homo sapiens ancestors traveled 50,000-55,000 years ago, leaving Africa to other promising lands on the Eurasian continent. More specifically, that path marks countless love species of theirs and other homin belonging to the extinct species of his genus.According to the main author – Dr. João Teixeira, a group of adults from Central – North Central Africa has left their homeland to the north. In present-day Egypt, this group splits into two branches, one heading toward present-day Algeria, one moving to the Middle East and meeting Neaderthals in present-day Saudi Arabia – Iraq. Many heterosexual marriages happened. The Neaderthals became extinct shortly after (about 30,000-50,000 years ago) but they managed to leave their lineage in the genome of ancient Homo sapiens.

After that, the ancestors, with many individuals having crossed Neanderthals, split into two groups, one going towards Europe and staying, one moving to Southeast Asia. On the way, in today’s Iran-Pakistan region, our ancestors met a mysterious extinct species, temporarily called “Hominin extinct 1”, mixed with blood again.

This group continues on to what is probably near the border of today’s Myanmar Myanmar, branching again. The group heads north to meet the extinct Denisovans, which reside in present-day Tibet, and fall in love again.

The group turns south across Southeast Asia – which may have once remained a strip of land – to the area of Indonesia. They are called Australo – Papuan, ancestors of present-day Indonesians and Australians. The group met again and fell in love with another group of Denisovans.

Their descendants continue to split. A group with similar genetic characteristics to Filipinos now moves to the Philippines and mate with the Denisovans again; while the group headed towards Australia and on their way across the area around the island of Flores in present-day Indonesia, they mingled with the unidentified fourth extinct humanity, known as “extinct Hominin 2”.

The exciting research has just been published in the journal PNAS.
