=== Archaeobotanical methodology ===
|Turkey
In the early 1970s Hillman recognised that traditional crop-processing in the mostly unmechanised village of Asvan led to distinctive, consistent assemblages of crop seeds, chaff and weed seeds that could also be recognised in archaeobotanical samples.<ref>{{Cite journal|last=Hillman|first=Gordon|date=1973-12|title=Crop Husbandry and Food Production: Modern Basis for the Interpretation of Plant remains|url=https://doi.org/10.2307/3642543|journal=Anatolian Studies|volume=23|pages=241–244|doi=10.2307/3642543|issn=0066-1546}}</ref> Contemporary analysis of archaeobotanical samples by [[Robin Dennell]] and others had recognised this variation, with the implication that ancient seed assemblages could not be treated uncritically as representative of crop use, but had not identified the close association with crop processing stages.<ref name=":0">{{Citation|last=Fuller|first=Dorian Q|title=Routine Activities, Tertiary Refuse, and Labor Organization:: Social Inferences from Everyday Archaeobotany|date=2014|url=http://www.jstor.org/stable/j.ctt1814hr4.14|work=Ancient Plants and People|pages=174–217|series=Contemporary Trends in Archaeobotany|publisher=University of Arizona Press|isbn=9780816527106|access-date=2018-08-06|last2=Stevens|first2=Chris|last3=McClatchie|first3=Meriel}}</ref> Further fieldwork by [[Glynis Jones (archaeologist)|Glynis Jones]] in Greece put Hillman's results onto a firmly quantified basis, and this mode of interpretation of plant remains - in terms of crop processing stages such as winnowing and sieving - is now a standard component of archaeobotany, particularly in the Old World.<ref name=":0" /> Many of Hillman's students carried out ethnoarchaeological work, for example Sarah Mason and Mark Nesbitt in Turkey<ref name=":2">{{Citation|last=Mason|first=Sarah|title=Acorns as food in southeast Turkey:: Implications for prehistoric subsistence in Southwest Asia|date=2009|url=http://www.jstor.org/stable/j.ctt1cfr8jt.16|work=From Foragers to Farmers|pages=71–85|series=Papers in Honour of Gordon C.

Hillman stressed the importance of first-hand knowledge of the ecology of wild food plants. The results of his botanical fieldwork were most fully explored for the site of [[Tell Abu Hureyra|Abu Hureyra]], for which his 1996 paper and 2000 book make extensive use of current day plant distribution to model the availability of wild cereals and other foodstuffs in the [[Epipalaeolithic Near East|Epipalaeolithic]] period.<ref>{{cite book |last=Hillman |first=Gordon |editor-last=Harris |editor-first=David R. |title=The origins and spread of agriculture and pastoralism in Eurasia |publisher=UCL Press |date=1996 |pages=159-203 |chapter=Late Pleistocene changes in wild plant-foods available to hunter-gatherers of the northern Fertile Crescent: possible preludes to cereal cultivation |isbn=978-1857285383}}</ref> Hillman also carried out experimental harvesting of wild cereals, leading to highly influential work with the geneticist Stuart Davies on modelling the potential speed of [[wheat]] domestication.<ref>{{Cite journal|last=HILLMAN|first=GORDON C.|last2=DAVIES|first2=M.

Current interpretations of archaeological data by [[Dorian Fuller]] and others point instead to a prolonged process of domestication<ref>{{Cite journal|last=Fuller|first=D.

Difficulty in identifying the fragmented plant remains characteristic of early sites led Hillman to build an excellent seed reference collection.

Two important sets of archaeological food remains came to Hillman's laboratory and sparked his wider interest in ancient food. The stomach contents of [[Lindow Man]] dated to the Iron Age, about 2000 year ago. Analysis by Hillman's student Tim Holden found Hillman collaborated with food scientists Tony Leeds and Peter Ellis at [[King's College London]], leading to nutritional analyses of acorns<ref name=":2" /> and sea club-rush (''Bolboschoenus maritimus'') tubers<ref>{{Cite journal|last=Wollstonecroft|first=Michèle M.|last2=Ellis|first2=Peter R.|last3=Hillman|first3=Gordon C.|last4=Fuller|first4=Dorian Q.|date=2008-06-06|title=Advances in plant food processing in the Near Eastern Epipalaeolithic and implications for improved edibility and nutrient bioaccessibility: an experimental assessment of Bolboschoenus maritimus (L.)

Despite taking early retirement in his mid-fifties, Hillman published over 80 papers (many very long), two co-authored books (''Village on the Euphrates. From foraging to farming at Abu Hureyra'', 2000; ''Wild food'', 2007), and one co-edited book (''Foraging and farming: the evolution of plant exploitation'', 1989).<ref>{{Cite web|url=http://www.homepages.ucl.ac.uk/~tcrndfu/hillman.htm|title=Gordon C.
