Project Title: Tracing the influence of cultivation on the whakapa of endemic NZ plants with molecular markers

The domestication of plants and animals was the most important development in human history during the past 13 000 years. Most crops are thousands of years old, with aspects of their initial domestication indeterminable. However, the relatively recent settlement of New Zealand by Maori provides a unique opportunity to investigate the early phase of crop domestication. We shall use genetic analyses of four endemic New Zealand plants cultivated by Maori to examine recent domestication: karaka, rengarenga, whau, and coastal kowhai. Prior to human arrival these species are thought to have been restricted to the northern North Island. Their occurrence in the southern North Island, the South Island, and distant Chatham and Kermadec Island groups, which is strongly associated with M?ori archaeological sites, is considered to result from translocations as part of their cultivation. Our analyses will reveal information about the number of times each species was brought into cultivation and the way in which domestication has reduced genetic diversity in the cultivated populations. Our genetic data, combined with traditional oral histories, where available, will reflect and illuminate pre-European Maori settlement routes and mobility.
