Evidence that the nuclear family dates back to the Stone Age has been unearthed for the first time by scientists. Here is a link to the story in a British online journal called the Telegraph. Although the article does not go into detail about DNA, the study looked at mtDNA, yDNA and autosomal DNA from the site. Three males (a man and two young boys) were tested as Haplogroup R1a and determined to be father and sons from their yDNA. Today Haplogroup R1a is largely associated with Slavic populations in Eastern Europe and is not commonly found in the British Isles.
