n the middle of March 2009, a group of 22 archaeologists, archaeobotanists, archaeozoologists, a geneticist, and a physical anthropologist took a six-day trip. We stayed in the same geographic location — a lovely hacienda near Merida in the Yucatan of Mexico. We were well cared for and fed. But it was an intense and demanding journey and, at the same time, one of those rare opportunities for like-minded individuals (we use that term loosely) to get together and explore a subject of shared interest, even fascination.
The focal point of the conference was the origins of agriculture. We hoped to bring together new data and new ideas to push our understanding of this remarkable phenomenon further along. The transition from hunting to farming is perhaps the most important in our human past. Virtually everything we know and do today stems from this extraordinary transformation.
A multitude of new developments concerned with the origins and spread of agriculture have taken place in recent years. New fieldwork and new sites in new and old places, more radiocarbon dates, and new methods have documented earlier transitions to agriculture in parts of Asia, the south Pacific and the Americas. Studies of microscopic plants remains, especially starch grains and phytoliths, have revolutionized identification of domesticated plants. Advances in the genetics of domestication, utilizing ancient DNA to examine the relationships among prehistoric domestics, are beginning to resolve standing questions about where and when. There are at least 10 different places now around the globe with reasonable claims to being an original center of domestication. The time is ripe to assemble his new information, to sift and winnow, to summarize our current understanding of the origins and spread of agriculture, and to move ahead.
Our group came to the conference with a number of biases — there was an Old World bias, an East Asia bias, a plant bias, a male bias, an age bias, one wag even suggested an anti-camel bias. Some might conclude that our conference was not successful. At the end of our time together, we did not learn why agriculture developed. We did not even agree on whether its causes are global or local. There were two groups, particularists and globalists, who saw explanations of the origins of agriculture largely from one of these two perspectives.
During the meeting itself and looking back now, however, there is a strong feeling that the conference was indeed a success and that each of us came away better informed about the prehistoric transition to farming. A number of factors were involved in that success. The participants were passionate, the ideas powerful, the information thought-provoking. We came to learn new facts, examine a wide range of variables, and use our knowledge to evaluate current explanations and to explore new ideas for understanding what took place at the origins of agriculture. Above all we wanted to think in new directions about this large, complex, and obstinate issue. Specific, individual knowledge and bias were critical for our discussions.
Our goal for the conference was to develop and explore a rich and productive dialog among scholars from diverse branches of archaeology and related disciplines focused on the beginnings of farming. That happened. One of the more important aspects of our meeting was the leveling of disciplines that took place. Archaeobotanists, archaeozoologists, and archaeologists, all more or less equally represented, broke down the walls that sometimes hinder discussion among these specialties and moved onto new ground. We were further informed by the presence of a human demographer and an expert on ancient DNA.
We were a volatile mix of scholars, from many times and places. There was for the first time at an international meeting a major emphasis on the origins of agriculture in East Asia. Lesser known regions such as Papua New Guinea, Africa, and Eastern North America were included in our discussions. Lots of new information was presented from East Asia, Africa, Central and South America. The antiquity of domestication has been pushed deeper into the past in many areas. Today, an eerie synchronicity in the timing of the first domesticates around the end of the Pleist
