Scientists unearth ancient Papua New Guinea artifacts in the highlands of the island that settle a longstanding archaeological argument regarding the emergence of complex culture on the island.

About 10,000 years ago, the climate changed to better suit the planting of crops and the Neolithic revolution that brought about agriculture emerged in different parts of the world at different times. In Europe and Asia it is known that at this time cultural complexity developed as people began settling and living together on farms.

But archaeologists have now discovered buried artifacts on the island of Papua New Guinea, which suggest ancient people began farming and making tools, arts and crafts around the same time as their Eurasian contemporaries.
