Human history was transformed with the advent of agriculture in the Fertile Crescent with wheat as one of the founding crops. Although the Fertile Crescent is renowned as the center of wheat domestication, archaeological studies have shown the crucial involvement of Catalhoyuk in this process. This site first gained attention during the 1961-65 excavations due to the recovery of primitive hexaploid wheat. However, despite the seeds being well preserved, a detailed archaeobotanical description of the samples is missing. In this article, we report on the DNA isolation, amplification and sequencing of ancient DNA of charred wheat grains from Catalhoyuk and other Turkish archaeological sites and the comparison of these wheat grains with contemporary wheat species including T. monococcum, T. dicoccum, T. dicoccoides, T. durum and T. aestivum at HMW glutenin protein loci. These ancient samples represent the oldest wheat sample sequenced to date and the first ancient wheat sample from the Middle East. Remarkably, the sequence analysis of the short DNA fragments preserved in seeds that are approximately 8400 years old showed that the Catalhoyuk wheat stock contained hexaploid wheat, which is similar to contemporary hexaploid wheat species including both naked (T. aestivum) and hulled (T. spelta) wheat. This suggests an early transitory state of hexaploid wheat agriculture from the Fertile Crescent towards Europe spanning present-day Turkey.


Exploring the evolutionary history of Anatolian neolithic sheep using modern and ancient genomics
Yurtman, Erinç; Somel, Mehmet; Department of Biology (2019)
The transition from hunting-gathering to sedentism happened in West Asia in the early Holocene, eventually giving way to the establishment of agriculture and livestock breeding. In this process, domestication of wild animals played crucial role for human settlements. The domestication center of sheep, among the main four livestock species, is thought to have been within Anatolia. Previous archaeozoological studies also suggested that after domestication this species migrated with human populations to other ...

The Neolithic Transition to village life and food production first emerged in the Fertile Crescent (c.10th and early 9th millennium BCE) and fundamentally reshaped human history. Although this transition involved major changes in human lifestyle, the social organization and traditions of the earliest sedentary communities is poorly understood. Here, we investigate genetic relatedness patterns among co-buried individuals within domestic structures in Neolithic Anatolia by studying 22 newly generated ancient ...
Phylogenetic relationships among Triticum L. and Aegilops L. species as genome progenitors of bread wheat based on sequence diversity in trnT-F region of chloroplast DNA

Cultivated wheat, (Triticum aestivum L.), is one of the most important food crops in the world. The Aegilops L. genus is frequently utilized by plant breeders for improving the current wheat cultivars due to their close relationships. Therefore, understanding the phylogenetic relationships among the species of these genera is not only valuable for plant taxonomy, but also for plant breeding efforts. The presented phylogenetic analysis was based on the sequences of trnT-F chloroplast DNA containing three non...
Archaeogenomic analysis of population genetic relationships and kinship patterns in the sedentary societies from neolithic anatolia
Yaka, Reyhan; Somel, Mehmet; Özer, Füsun; Department of Molecular Biology and Genetics (2020-1-12)
The Neolithic way of life first emerged in the Fertile Crescent (c.10thand early 9thmillennium cal BCE) and quickly spread to neighbouring regionssuch as Central Anatoliaand Cyprus,and eventually further westwards. This transition involved to fundamental changes in human lifestyle,with the first emergence of villages during the early Neolithicandthe later the growing reliance on farming and herdingduring the late Neolithic periods. Changes in the social organization of sedentary communi...

Over multiple millennia, from the earliest traces of long-term occupation of camp sites (ca 20,000 BC) to the development of full-scale farming (ca 8000–6000 BC), the Neolithic transition in southwest Asia gradually shaped human societies in dramatic ways (Nadel 2002; Maher et al. 2012; Asouti, Fuller 2013). Here we present recent insights from ancient genomics studies into these societies while focusing on two questions: the population processes driving cultural change in Neolithic central Anatolia and gen...
