Archaeologists excavating a cave in South Korea have found evidence that suggests human beings were using sophisticated techniques to catch fish as far back as 29,000 years ago, much earlier than experts previously thought. Carbon dating procedures on the fourteen limestone sinkers, unearthed in the eastern county of Jeongseon in June, have pushed back "the history of fishing by nets by some 19,000 years," Yonsei University Museum director Han Chang-gyun told AFP. Previously, researchers had excavated sinkers in Japan's Fukui Prefecture and South Korea's Cheongju city, but those discoveries were all dated back to the Neolithic Era and believed to be around 10,000 years old, Han said.
