From bowls to pots: The dairying revolution in Northwest Turkey, a view from Barcin Höyük, 6600 to 6000 BCE.

Research has identified Northwest Turkey as a key region for the development of dairying in the seventh millennium BCE, yet little is known about how this practice began or evolved there. This research studies Barcin Höyük, a site located in Bursa's Yenisehir Valley, which ranges chronologically from 6600 BCE, when the first evidence of settled life appears in the Marmara Region, to 6000 BCE, when Neolithic habitation at the site ceases. Using pottery sherds diagnostic by vessel category and type, this paper aims at identifying which ones may have been primarily used to store, process, or consume dairy products. Organic residue analysis of selected samples helped address the process of adoption and intensification of milk processing in this region over time. The lipid residue data discussed in this paper derive from 143 isotopic results subsampled from 173 organic residues obtained from 805 Neolithic potsherds and suggest that bowls and four-lugged pots may have been preferred containers for processing milk. The discovery of abundant milk residues even among the earliest ceramics indicates that the pioneer farmers arrived in the region already with the knowhow of dairying and milk processing. In fact, these skills and the reliance on secondary products may have given them one of the necessary tools to successfully venture into the unfarmed lands of Northwest Anatolia in the first place.

An early Prussian study on the composition of milk from 1871.

Connections between the 2 scientific fields of physiology and dairy science have existed for a very long time-since the 19th century. One possible explanation for this circumstance could have been the necessity for financial support, which might have played a significant role for many theoretical physiologists to conduct studies on dairy products. This study discusses a correspondence written by the physiologist R. Gscheidlen to J. A. Winter, the main editor of the German (previously Saxon) journal "Schmidt's Yearbooks on the Entire Field of Domestic and Foreign Medicine" ("Schmids Jahrbücher der in-und ausländischen gesammten Medicin"). Gscheidlen submitted a review manuscript on the composition of milk to Winter's journal. In that work, which was published later as the first issue's very first article of the first volume (of in total 4 quarterly volumes) in 1871, Gscheidlen mainly refers to Eduard Kemmerich, who later became a pioneer of cattle breeding in Argentine. Therefore, studies on dairy products and on dairy science, although regularly not very significant from a theoretical and physiological point of view, obviously had concrete implications for practical purposes. Furthermore, other parts of Winter's journal, volume 1871, indicate that Gscheidlen tried to connect these studies with his early theoretical works on physiological metabolism. These theoretical studies included experiments that already explored basic principles of the urea cycle from today's point of view. Of course, these works, which were partly carried out on animals, must have been extravagant and expensive. For that reason, it is possible to assume that early dairy science and other scientific fields in Germany around 1870, which were linked to the developing food industry, had a very significant influence on the advances in theoretical metabolism physiology.
