That was a nice article. Scientists confirmed that there are close links between Ethiopia and groups outside of Africa, which is evidence of long-ago genetic mixing between Ethiopian populations and Syrian and Israeli people. Not surprising, of course. Already in the Naqada Period, merchants sailed from Egypt to Syria and Nubia. They continued to do so for centuries. It would have been real news if there had been no genetic mixing.
Unfortunately, scientists do not like to confirm what is already known. Or, to be more precise: they themselves have no problem with it, because a confirmation is also interesting, but their financers do not like it. So, the article is introduced by referring to the visit of the Queen of Sheba to Jerusalem (1 Kings 10.1-13). And voilà, all journalists copy it, although Sheba is not in Ethiopia but in Yemen. I expect that the scientists involved will, when they establish genetic mixing between the Levant and Belgium, refer to Rhabanus Maurus’ story that Joseph of Arimathea visited England.
Why is the Bible always quoted? If the Thera explodes in 1629 BCE, we get a press release that Moses, during his travel through the desert, followed a pillar of cloud by day and a pillar of fire by night (Ex. 13.21). If scientists tell about lack of oxygen causing people to hallucinate, they refer to Moses on the mountain (Ex. 19.3). If archaeologists find an extremely old sanctuary between Euphrates and Tigris, they start talking about the Garden of Eden (Gen. 2.8-14). The golden rule appears to be: by referring to the Bible, you will attract large crowds, and can look forward to a miraculous multiplication of funds.
Of course the Bible does mention that Moses followed a pillar of clouds, that Moses went up a mountain, and that God planted a garden between four rivers. The theories founded upon these stories may be nonsensical, but at least there are fitting quotes in the Bible. But there is not a single line in the Bible that can be used to bring the Yemenite Queen to Ethiopia. And the medieval legend that is adduced, is precisely that: a medieval legend.
If scientists start referring to the Queen of Sheba for the genetic mixing in Ethiopia, something is very seriously wrong. Quack historians at least quote things that are actually in the sources. Official scientists are not even interested in that.
