Are Falashans (Black Ethiopians) Jews? or Native Ethiopian tribe?

They are mixed native Black Ethiopians with immigrant Semitic Whites(Arabs and Jews).They claim Semitic heritage as Black because they believe Semitic Whites are Black-i.e.- the Semitic White Chaldeans. They practice the Jewish religion, not ethnicity. Many do express Semitic facial features, especially the raised hooked or pointed nose(versus the flat,wide Black African nose) and thin lips.Their only claim to being Jews by ethnicity is through admixture and by religion, practicing.In other words, they are Mulattos(Black/Semitic White mix) practicing Judaism(faith).Where and when the admixture occured is controversial. They, themselves, based on a legend of theirs, claim to be one of the lost tribes of Israel.They believe they are descendants resulting from the union of King Solomon and the Queen of Sheba whose son was Menelek I.It is also open to dispute whether the Queen of Sheba was Black or Semitic White(Arab) as she ruled over regions encomping both cultures and most likely was mixed.From what is known of her, she did not present Black features.Black features usually dominate in 1st generation mixes and apparently Menelek I one resembled his father, Solomon so much ,so he was recognizedimmediately, indicating most likely, since Black features were not apparent, the Queen of Sheba was Semitic White Arab or Semitic White /Ethiopian Black mix.
