From Queen of Sheba's gift? Evidence of genetic mixing by Stephanie Pappas

Very King Solomon's Mines like.

The results revealed that the Ethiopian genome is less ancient than those of some South African populations, and that Ethiopian genes are quite diverse. Language hinted at genetics, the researchers found: Speakers of Semetic and Cushitic tongues were shown to have genomes about half comprised of genes from non-African origins. Other groups were characterized by mixes of eastern and western African genes.

Tracing the genomic changes, the researchers found that the non-African and African genes first mingled about 3,000 years ago rather than during more recent times, the researchers reported Thursday in the American Journal of Human Genetics. [ Most Tragic Love Stories in History ]

That timeline confirms what linguistic studies have suggested about links between the Middle East and Ethiopia during this time period, the researchers wrote. It also matches records and tales of the reign of the Queen of Sheba from about 1005 to 955 B.C., when trade routes were established and a royal son, perhaps, was born. Relations between the Horn of Africa and the Middle East would continue for centuries.

"These long-lasting links between the two regions are reflected in influences still apparent in the modern Ethiopian cultural, and, as we show here, genetic landscapes," the researchers wrote.
