Çatalhöyük, a settlement in Turkey that dates back more than 9,000 years, has attracted intense interest for its structural complexity and hints of an egalitarian and possibly matriarchal society. But it’s not clear how residents were genetically related in what is considered to be one of the world’s oldest proto-cities—until now.
Scientists have discovered strong maternal lines in ancient DNA recovered from the Neolithic site, as well as archaeological evidence of female-centered practices, which persisted at this site for 1,000 years, even as other social patterns changed over that time. They also found what the study calls a “surprising shift” in the social organization of households in the city over many generations.
The results don’t prove Çatalhöyük society was matriarchal, but they demonstrate that “male-centered practices were not an inherent characteristic of early agricultural societies” which stands in “stark contrast” to the clearly patriarchal societies established later across Europe, according to a study published on Thursday in Science.
“Çatalhöyük is interesting because it's the earliest site with full dependence on agriculture and animal husbandry, and it’s larger than its contemporaries,” said Eren Yüncü, a postdoctoral researcher at Middle East Technical University who co-led the study, in a call with 404 Media. “Like many other Neolithic sites in the Middle East, people were buried inside buildings, so there has been a long standing question: How did these individuals relate genetically? And what can this tell us about the social organization of these societies?”
“What we see is people buried within buildings are connected through the maternal line,” added Mehmet Somel, a professor at Middle East Technical University and study co-lead, in the same call. “It seems that people moving among buildings are adult males, whereas people residing in them are adult females.”
Çatalhöyük was erected in Turkey’s Anatolia region around 7,100 BCE and was home to about 5,000 to 7,000 people at its peak, before the site was abandoned by around 5,700 BCE. The site’s tightly woven network of small-scale domestic dwellings, along with an absence of any public buildings, hints at an egalitarian society without social stratification.
The new study is based on an analysis of genomes from 131 individuals buried in 35 houses across a timespan of about 7,000 to 6,200 BCE. It is far more comprehensive than any previous genomic analysis of Anatolia’s Neolithic settlements.
“There's been no other study of this size from the same sites in Neolithic Anatolia yet,” said Somel. “The previous work we published had about ten to 15 individuals. Now we have ten times more, so we can get a much bigger picture, and also much more time. Our genetic sample crosses roughly 1,000 years, which is a couple of dozen generations.”
The social pattern of males moving into new locations while females remain in their natal homes is known as matrilocality. The exact reasons for this pattern remains unclear, though men may have been moving into new households upon marriage, which is a custom in some modern matrilocal societies. Somel cautioned that Çatalhöyük is a special case because the team only found evidence of matrilocality within the settlement, estimating that female offspring remained connected to their natal buildings between 70 to 100 percent of the time, whereas adult males moved to different buildings. However, immigrants to Çatalhöyük from other populations did not seem to show a strong male or female bias.
The reverse system, called patrilocality, is characterized by females moving to new locations while adult males stay in natal communities. Patrilocality is by far the more common pattern found in archaeological sites around the world, but matrilocality is not unprecedented; studies have found evidence for this system in many past societies, from Micronesia to Britain, which are more recent cultures than Çatalhöyük.
The abundance of female fertility figurines at Çatalhöyük has long fueled speculation about a possible matriarchal or goddess-centered cult. Men and women at Çatalhöyük also consumed similar foods and may have shared social status. In the new study, Yüncü, Somel, and their colleagues report that female infants and children were buried with about five times as many grave goods as males, suggesting a preferential treatment of young female burials. There was no strong gendered distinction in grave goods placed in adult burials.
The team was also surprised to discover that the social organization of households changed across time.
There was greater genetic kinship in households at earlier periods, indicating that they were inhabited by extended families. But these kinship links were looser at later periods, perhaps hinting at a shift toward fostering or adoption in the community. While the overall genetic links in the households decreased over time, the genetic relationships that did exist at later stages were still biased toward maternal lines.
The possibility of an early matriarchy is tantalizing, but the nature of gender roles at Çatalhöyük remains elusive and hotly debated. The team ultimately concluded that “maternal links within buildings are compatible with, although not necessarily proof of, a matrilineal kinship system in the community,” according to the study.
“This discussion is an interesting one, but it's not the end of the story,” Yüncü said. “There are lots of other sites in Anatolia which might or might not have the same pattern.”
“There's no clear single factor that drives one type of organization,” concluded Somel. “We need to do more studies to really understand this.”
