Hayden (1990) argued that early cultigens and trade items had more prestige value than utility, and suggested that agriculture began because the powerful used its products for competitive feasting and accrual of wealth. These wild relatives are sources of genes to improve crops for higher yield and disease and pest resistance, among other traits. Get PDF (14 MB) Abstract. In large measure these advances are attributable to new methods for documenting domestication in plants and animals.

Notably, a few isolates from the Canadian Arctic formed a monophyletic group within the D 4 subgenotype from indigenous populations in Australia and Remote Oceania. They also show that the sweet potato most likely arrived in Polynesia by long-distance dispersal in pre-human times.
