I was torn between making this post on the DNA Forum, the Caribbean Forum, the African Forum, or the Main Forum. Deciding to err on the side of reaching the most readers, I decided to post here (realizing that it may be moved to a more appropriate forum).
Today, at 10A PST (not sure of the time in other time zones; check link below) the Sundance Channel is airing a film called "Motherland: A Genetic Journey." The film pertains to a study of the genetic ancestry of Britain's African-Caribbean community. Though it relates to Afro-Caribbean Britons, there certainly may be lessons to be learned by those of us who are also interested in DNA research, as it relates to genealogy.
If you miss it today, it will air at other future dates on Sundance. I am providing a link:
