In the study, published Tuesday (April 14) in the journal Antiquity, researchers analyzed the DNA of 22 people from five tombs in the county of Caithness and the Orkney Islands in northern Scotland. The tombs were used between 3800 and 3200 B.C., when prehistoric Scotland was transitioning from foraging to farming.
Using ancient DNA analysis, researchers have now been able to raise and answer questions about kinship in this period. For example "how often were tombs used to contain the remains of close genetic relatives? How often were individuals selected for inclusion because they were related along the male line?" study co-author Chris Fowler, an archaeologist at Newcastle University in the U.K., said in a statement.
In the tombs, the researchers found close genetic relatives, all of whom were linked along the male line. Two tombs held father-and-son pairs, and one contained brothers. Half brothers or paternal uncle-and-nephew pairs were found in two neighboring tombs. And one tomb — located in northeast Scotland on Loch Calder — contained the only evidence ever found of a father, son and grandson buried together in Neolithic Scotland.
"It is incredible to think that, over 5,000 years after these people were deposited in these tombs, we were able to reconstruct how they were related to each other through the analysis of ancient DNA," study lead author Vicki Cummings, an archaeologist at Cardiff University in Wales, said in the statement. "This study shows that the people building these monuments placed a particular emphasis on the male line."
The female skeletons that the researchers studied did not show any close connections. There were no mother-daughter or sister pairs in tombs, for example, and the closest genetic relationship between any two women was fifth-degree, which equates to first cousins once removed.

However, two females buried in tombs on an Orkney island were genetically related to males buried in mainland tombs, suggesting that women may have played a key role in maintaining "webs of descent" across the water, the researchers wrote in the study.
While experts had long assumed that Neolithic people in this area organized themselves along the male line, the new study confirms it.
"These results are consistent with the interpretation that patrilineal descent was traced in this region," Cummings said. "For the people introducing the Neolithic into Britain, this social connection may have been as important as pots, cows and axes."
