History, Language & Culture Papua New Guinea

Archaeological evidence indicates that humans first arrived in Papua New Guinea around 42,000 to 45,000 years ago. They were descendants of migrants out of Africa, in one of the early waves of human migration.

Agriculture was independently developed in the New Guinea highlands around 7000 BC, making it one of the few areas in the world where people independently domesticated plants. A major migration of Austronesian-speaking peoples to coastal regions of New Guinea took place around 500 BC. This has been correlated with the introduction of pottery, pigs, and certain fishing techniques.

In the 18th century, traders brought the sweet potato to New Guinea, where it was adopted and became a staple food. Portuguese traders had obtained it from South America and introduced it to the Moluccas. The far higher crop yields from sweet potato gardens radically transformed traditional agriculture and societies. Sweet potato largely supplanted the previous staple, taro, and resulted in a significant increase in population in the highlands.

Although by the late 20th century headhunting and cannibalism had been practically eradicated, in the past they were practised in many parts of the country as part of rituals related to warfare and taking in enemy spirits or powers. In 1901, on Goaribari Island in the Gulf of Papua, missionary Harry Dauncey found 10,000 skulls in the island's long houses, a demonstration of past practices. According to Marianna Torgovnick, writing in 1991, "The most fully documented instances of cannibalism as a social institution come from New Guinea, where head-hunting and ritual cannibalism survived, in certain isolated areas, into the Fifties, Sixties, and Seventies, and still leave traces within certain social groups.
