The University announced Libby's results in a news release issued in connection with the article.Libby collaborated extensively with Oriental Institute archaeologist Robert Braidwood in conducting C-14 tests on artifacts of known age from Mesopotamia and Western Asia, including wood from an Egyptian mummy's casket.Geologists measure the abundance of these radioisotopes instead to date rocks.It was while working in the Kent Laboratory building in the 1940s that researchers developed radiocarbon dating—an innovative method to measure the age of organic materials.Over time, carbon-14 decays radioactively and turns into nitrogen.

This work enabled Libby and postdoctoral associate James Arnold to publish a carbon-14 atomic calendar in the Dec. They documented the viability of the technique with this article, which compared the ages of samples of known age with the ages as determined by their radiocarbon content.Archaeologists testing the ages of artifacts from multiple sites across the Eastern and Western hemispheres found that civilization originated simultaneously around the world rather than in Europe.
