Previously, ancient Eurasian genomes had revealed three ancestral populations that contributed to contemporary Europeans in varying degrees, says Manica.

«We were surprised by the results, because we expected a substantial fraction of the genome of the red wolf and eastern wolf, maybe 20 % to 30 %, would be derived from a long - distinct species, much as about 1 % to 4 % of [human] Eurasian genomes derive from Neanderthals,» said Wayne.

Manica says the Bantu expansion may well have helped carry the Eurasian genomes to the continent's furthest corners.

Earlier studies have shown that one to six percent of modern Eurasian genomes were inherited from ancient hominins, such as Neanderthal or Denisovans.

Co-author Andrea Manica, a population geneticist at the University of Cambridge in the United Kingdom, has posted a note online explaining that incompatibility between two software packages used to compare Mota's genome with the reference human genome led the software program to simply drop certain DNA variants, with the result that all living Africans seemed to have inherited more «Eurasian» DNA than they actually did.

A 2015 study in Genome Research, for example, estimated that 25 percent of modern Eurasian wolf DNA actually comes from interbreeding with domesticated dogs.

The ancient genome predates a mysterious migratory event which occurred roughly 3,000 years ago, known as the «Eurasian backflow», when people from regions of Western Eurasia such as the Near East and Anatolia suddenly flooded back into the Horn of Africa.

By comparing the ancient genome to DNA from modern Africans, the team have been able to show that not only do East African populations today have as much as 25 % Eurasian ancestry from this event, but that African populations in all corners of the continent — from the far West to the South — have at least 5 % of their genome traceable to the Eurasian migration.

«Genomes from this migration seeped right across the continent, way beyond East Africa, from the Yoruba on the western coast to the Mbuti in the heart of the Congo — who show as much as 7 % and 6 % of their genomes respectively to be West Eurasian,» said Marcos Gallego Llorente, first author of the study, also from Cambridge's Zoology DepaGenomes from this migration seeped right across the continent, way beyond East Africa, from the Yoruba on the western coast to the Mbuti in the heart of the Congo — who show as much as 7 % and 6 % of their genomes respectively to be West Eurasian,» said Marcos Gallego Llorente, first author of the study, also from Cambridge's Zoology Depagenomes respectively to be West Eurasian,» said Marcos Gallego Llorente, first author of the study, also from Cambridge's Zoology Department.

The genome sequence of a 24,000 - year - old Siberian individual has provided a key piece of the puzzle by demonstrating genomic signatures that are basal to present - day western Eurasians and close to modern Native Americans.

The researchers compared the genomes in these individuals to those from pure coyotes and Eurasian wolves.

A new genome analysis method has confirmed that Neanderthals interbred with ancestors of Eurasians, a new study reports.

To evaluate these options, the manuscript contrasts sequence information from Egyptian and Ethiopian genomes and with a panel of Eurasians, showing that Egyptians are the modern Africa population harboring the strongest signal of that past migration and, hence, favoring a northern exit as the most likely route out of Africa.

The international study showed that around 60 per cent of Eurasian grey wolf genomes carried small blocks of the DNA of domestic dogs, suggesting that wolves cross-bred with dogs in past generations.
