Selective funerary practices can inform about social relationships in prehistoric societies but are often difficult to discern. Here we present evidence for an age-specific practice at the Neolithic site of Çatalhöyük in Anatolia, dating to the 7th millennium BCE. Among ancient DNA libraries produced from 362 petrous bone samples, those of subadults contained three times higher average human DNA than those of adults. This difference in organic preservation was also confirmed by FTIR analysis. Studying similar datasets from seven prehistoric and historical sites, we found a similar age-related difference in only one cemetery. We propose that the organic preservation difference with age was caused by the special treatment of chosen corpses before interment, such as defleshing or drying, which was more frequently applied to Çatalhöyük adults and promoted organic decay.

Western Anatolia has been a crucial yet elusive element in the Neolithic expansion from the Fertile Crescent to Europe. Using 30 new palaeogenomes from Anatolia c.8000-6000 BCE we describe the early Holocene genetic landscape of Western Anatolia, suggesting population continuity since the late Upper Pleistocene. Our findings indicate that the Neolithisation of Western Anatolia in the 7th millennium BCE was a multifaceted process, characterised by the assimilation of Neolithic practices by indigenous groups and the influx of populations from the east, their admixed descendants eventually laying the foundations of Neolithic Southeast Europe. Intriguingly, the observed diversity in material culture among Aegean Early Neolithic communities correlates with their geographical distances but not their genetic differences, signifying a decoupling between cultural developments and genetic admixture processes.

Arguments have long suggested that the advent of early farming in the Near East and Anatolia was linked to a ‘Mother Goddess’ cult. However, evidence for a dominant female role in these societies has been scarce. We studied social organisation, mobility patterns and gendered practices in Neolithic Southwest Asia using 131 paleogenomes from Çatalhöyük East Mound (7100-5950 BCE), a major settlement in Central Anatolia with an uninterrupted occupation and an apparent egalitarian structure. In contrast to widespread genetic evidence for patrilocality in Neolithic Europe, the Çatalhöyük individuals revealed no indication of patrilocal mobility. Analysing genetic kin ties among individuals buried in the same house (co-burials) across 35 Çatalhöyük buildings, we identified close ties concentrated within buildings and among neighbours in Çatalhöyük’s Early period, akin to those in the preceding Pre-Pottery Neolithic in Southwest Asia. This pattern weakened over time: by the late 7th millennium BCE, subadults buried in the same building were rarely closely genetically related, despite sharing similar diets. Still, throughout the site’s occupation, genetic connections within Çatalhöyük buildings were much more frequently connected via the maternal than the paternal line. We also identified differential funerary treatment of female subadults compared to those of males, with a higher frequency of grave goods associated with females. Our results reveal how kinship practices changed while key female roles persisted over one thousand years in a large Neolithic community in western Eurasia.

Bioarchaeology, a highly contextualized study of human remains embedded in their cultural and natural settings, is a multidisciplinary study of past human biological variation that draws upon allied fields in the natural, social, and medical sciences, as well as the humanities. This chapter focuses on how human remains enhance their knowledge about the lives of past people, and hence provides a deep temporal context for a better understanding of the world as it exists today. Bioarchaeologists direct most of their attention to human remains from the Holocene. Case reports of single, or perhaps a few, skeletons have always been an important part of bioarchaeology. This is especially true of paleopathology, where the identification of specific diseases, such as tuberculosis, has long been of interest. Patterning in age‐at‐death in large and well‐characterized skeletal samples provides perspectives on population structure and change that cannot be obtained from other sources.

Around 10,000 y ago in southwest Asia, the cessation of a mobile lifestyle and the emer-gence of the first village communities during the Neolithic marked a fundamental change in human history. The first communities were small (tens to hundreds of individuals) but remained semisedentary. So-called megasites appeared soon after, occupied by thousands of more sedentary inhabitants. Accompanying this shift, the material culture and ancient ecological data indicate profound changes in economic and social behavior. A shift from residential to logistical mobility and increasing population size are clear and can be explained by either changes in fertility and/or aggregation of local groups. However, as sedentism increased, small early communities likely risked inbreeding without maintaining or establishing exogamous relationships typical of hunter-gatherers. Megasites, where large populations would have made endogamy sustainable, could have avoided this risk. To examine the role of kinship practices in the rise of megasites, we measured strontium and oxygen isotopes in tooth enamel from 99 individuals buried at Pınarbası, Boncuklu, and Catalh€oy€uk (Turkey) over 7,000 y. These sites aregeographically proximate and, critically, span both early sedentary behaviors (Pınarbas ̧ıand Boncuklu) and the rise of a local megasite (Catalh€oy€uk). Our data are consistent with the presence of only local individuals at Pınarbası and Boncuklu, whereas at Catalh€oy€uk, several nonlocals are present. The Catalh€oy€uk data stand in contrast to other megasites where bioarchaeological evidence has pointed to strict endogamy. These different kinship behaviors suggest that megasites may have arisen by employing unique, community-specific kinship practices.

Climate change is a significant threat to human health, especially for societies already confronted with rising social inequality, political and economic uncertainty, and a cascade of concurrent environmental challenges. Archaeological data about climate and environmental change provide a source of evidence about the potential challenges we face and the long-term outcomes of different short-term adaptive strategies employed in the past. Bioarchaeologists and paleopathologists study human health in the Holocene using evidence from archaeological human skeletons and mummified remains. Our research provides a basis for understanding the health impacts of past climate and environmental change within an evolutionary and biocultural framework. Here we provide bioarchaeological case studies from the published literature and discuss their relevance to research priorities outlined in the United Nations Sustainable Development Goals. We discuss the impact of environmental marginalization, famine and nutritional insufficiency, infectious disease, violence, and migration in the past. Although the magnitude and the pace of current global warming exceed the parameters of climate change experienced by past societies, bioarchaeology provides valuable insights into how variation in human historical and socio-cultural circumstances shaped epidemiological patterns across the millennia. It also provides clarity on the constraints of modernity, including limits to mobility and increasingly high levels of structural inequality. By demonstrating how past human societies perceived and experimented with solutions to climate and environmental challenges, bioarchaeology contributes to current prediction, planning, and policy-making efforts for a more equitable and sustainable future.
