Can carbon dating go
which published the findings in its most recent issue.They began to cross-reference the reports from carbon-dating analysis with the actual ages of living organisms."It would help show whether or not modern man was around at the same time as the last of the Neanderthals," he said."That's a huge question."There's another big question in Guilderson's field: what about dating things to 55,000 years ago – 10 half-lives of carbon-14 – or even further back?
Y., reported today in the British journal Nature that some estimates of age based on carbon analyses were wrong by as much as 3,500 years.Scientists are debating whether they have enough information to do that."There's still enough wiggle room for lots of argument," Guilderson said. Since 1947, scientists have reckoned the ages of many old objects by measuring the amounts of radioactive carbon they contain.New research shows, however, that some estimates based on carbon may have erred by thousands of years.
