Edited by Greg Neyman. Hovind claims that living snails were carbon dated at 2, and 27, years old. Doesn't carbon dating or potassium argon dating prove the Earth is millions of years old? Both samples come from instances where "dead carbon" has been incorporated into the shells by the snails. The snails lived in an environment where ancient limestones contributed dead carbon.
Whenever the worldview of evolution is questioned, the topic of carbon dating always comes up. Here is how carbon dating works and the assumptions it is based upon. Radiation from the sun strikes the atmosphere of the earth all day long. This energy converts about 21 pounds of nitrogen into radioactive carbon
In Brazilian archaeological shellmounds, many species of land snails are found abundantly distributed throughout the occupational layers, forming a contextualized set of samples within the sites and offering a potential alternative to the use of charcoal for radiocarbon dating analyses. In order to confirm the effectiveness of this alternative, one needs to prove that the mollusk shells reflect the atmospheric carbon isotopic concentration in the same way charcoal does. The obtained dates fit the SH bomb curve within less than 15 years range, showing that certain species from the Thaumastus and Megalobulimus genera are reliable representatives of the atmospheric carbon isotopic ratio and can, therefore, be used to date archaeological sites in South America. Archaeological shellmounds are the testimony of the hunter-fisher-gatherer populations who first occupied the Brazilian coast. The archaeological remains usually recovered in such sites are charcoal fragments scattered or associated with hearths , human bones, lithic tools e.
Most everyone has heard of Carbon dating on the news or elsewhere sometime in the past years. In this article I hope to explain the theoretical and physical science behind Carbon dating, and discuss how it affects our lives and the validity of the process. Scientists use Carbon dating for telling the age of an old object, whose origin and age cannot be determined exactly by normal means.
