New Zealand's capital city is Wellington, while its most populous city is Auckland.Sometime between 12 CE, Polynesians settled in the islands that later were named New Zealand and developed a distinctive Māori culture.New Zealand is situated some 1,500 kilometres (900 mi) east of Australia across the Tasman Sea and roughly 1,000 kilometres (600 mi) south of the Pacific island areas of New Caledonia, Fiji, and Tonga.

“He did a good job of excavating, but he interpreted it totally wrong,” says Tom Higham, a 46-year-old archaeological scientist at the University of Oxford's Radiocarbon Accelerator Unit.

Space is filled with cosmic rays, which hit the upper layers of the Earth’s atmosphere.

Atomic nuclei, hit by these rays, fragment and smaller particles (neutrons) are created. The impact of a neutron upon a nitrogen-14 (14N) atom results in the removal of a proton and the formation of a particle of carbon-14.

Then, in the twentieth century, carbon dating found the bones to be about 22,000 years old — even though much of Britain was encased in ice and seemingly uninhabitable for part of that time.

When Higham eventually got the bones, his team came up with a more likely scenario: they were closer to 33,000 years old and one of the earliest examples of ceremonial burial in Western Europe.

This carbon dioxide becomes incorporated in plants through the process of photosynthesis, and into animals via the food chain.
