Oh we'd have loved a disreputable amorous priest on a bicycle!

The programme I watched ('The Incredible Human Journey' with Dr Alice Roberts, who I think is brilliant as a presenter) showed how Neanderthals did indeed mate with Homo Sapiens, but this didn't happen with black Africans actually in Africa. I was rather pleased about this. The Neanderthals are perfectly acceptable to me as ancestors, but of course this resulted in much knuckle-dragging teasing by my daft 'pedigree' husband! :)
I agree with you Donuel, the commercial DNA testing one can buy is probably extremely inaccurate, and the results are no doubt produced merely to fascinate the unwary. What I'd love to find is some African DNA in me, as I've been drawn to Africa all my life from the age of about four.
I've just watched that trailer for 'Roots' Jim, and I think it would have me sobbing if I watched the whole thing. (The original version did) The main character actor looks quite like my husband and many slaves were exported from western Cote d'Ivoire, but much earlier than the period covered.
I believe Kunta Kinte was from Gambia, a country I know well. Fortunately, the Senoufo tribe were safely out of it up in the north of Ivory Coast, and I don't believe any of them were enslaved.

meself, we might be long-lost cousins!(waves in greeting) But only by marriage. A Scots Weir was the husband of one of us.
