Dating is not necessary to demonstrate that evolution is a fact.Chronological sequence is all that is really required.In a separate article (Radiometric dating), we sketched in some technical detail how these dates are calculated using radiometric dating techniques.As we pointed out in these two articles, radiometric dates are based on known rates of radioactivity, a phenomenon that is rooted in fundamental laws of physics and follows simple mathematical formulas.Thus radioactive dating relies purely on assumptions.
This assumption is backed by numerous scientific studies and is relatively sound.
At the same time, the environment constantly produces new carbon-14, so that the percentage of carbon-14 in all living plants and animals remains fairly constant.
When an animal dies, it stops taking in new carbon.
Scientists place great faith in this dating method, and yet more than 50% of radiocarbon dates from geological and archaeological samples of northeastern North America have been deemed unacceptable after investigation.
While there is no proof that the rates were different in the past than they are today, there is also no proof that they were the same.
