Chickens to chili peppers
Date:4/17/2014

Suddenly there was a word for chili peppers. Information about archaeological remains of ancient chili peppers in Mexico along with a study of the appearance of words for chili peppers in ancient dialects helped researchers to understand where jalapeos were domesticated and highlight the value of multi-proxy data analysis. Their results are from one (Kraig Kraft et al.) of nine papers presented in a special feature issue of the Proceedings of the National Academy of Sciences on plant and animal domestication edited by Dolores Piperno, staff scientist emerita at the Smithsonian Tropical Research Institute and Curator of South American Archaeology at the National Museum of Natural History and Greger Larson of Durham University in England.

Humans evolved about 200,000 years ago. We spent 95 percent of human history as hunter-gatherers. Why did agriculture begin to emerge in human cultures about 12,000 years ago? Was it the result of a prime mover: divine inspiration, environmental change or population growth? What cultural and natural processes led to the domesticated species that supply most of the world's foods today? The complexity of these questions requires multidisciplinary research. Bringing together scientists from a wide range of disciplines involved in domestication studies, Larson and Piperno organized a meeting funded and hosted by the National Evolutionary Synthesis Centre in 2011. The PNAS special feature is a result of the meeting.

"Having archaeologists and geneticists talking to and collaborating with each other and a suite of new techniques to play with is radically changing the way we think about domestication," said Piperno.

The overview paper (Larson and Piperno et al.) that introduces the special issue emphasizes the need to use both archaeological and genetic evidence to sort out the unique processes of domestication that occurred at about the same time around the world from "predomestication cultivation"p
