Although Boltwood's resulting estimates for things like the age of Earth¿which he placed at around 2.2 billion years¿have since been significantly revised, he indicated correctly that our planet was far older than people had imagined possible.

In the decades that followed, scientists made important new discoveries about the structure and behavior of atoms, and they refined their existing dating techniques.

This was dealt with in the chapter by that name (chapter 1).

Second, generation of living organisms from non-living matter, or origin of life.

(Hint: It¿s not just carbon-dating anymore.) These days hardly a week goes by without important discoveries concerning the history of life on Earth making headlines.

Indeed, just last month researchers described a fossil that pushes the origins of key mammal features back some 45 million years.

The application of radiometric dating techniques began early in the 20th century.

The quantitative methods provided by these techniques had the potential for dating divisions of the geologic time scale and for estimating the age of the Earth itself.

Possible other sources of correlation Anomalies of radiometric dating Why a low anomaly percentage is meaningless The biostrategraphic limits issue Preponderance of K-Ar dating Excuses for anomalies Need for a double-blind test Possible changes in the decay rate Isochrons Atlantic sea floor dating Dating Meteorites Conclusion Gentry's radiohaloes in coalified wood Carbon 14 dating Tree ring chronologies Coral dating Varves Growth of coral reefs Evidence for catastrophe in the geologic column Rates of erosion Reliability of creationist sources Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium.It lists the succession of rock depositions that are recognized on and immediately beneath the Earth's surface.The standard stratigraphic column, based on fossil plant and animal assemblages from different European strata, is used to date fossils in strata from other parts of the Earth and is the foundation of the geologic time scale.This is an important topic, for evolutionists want the history of earth to span long ages in the hopes that this will make the origin and evolution of life more likely.Yes, an understanding of dating methods is important, but we should keep in mind that whether or not these dating methods are accurate, really has no direct relation to whether evolution has ever occurred or could occur. Evolution can only occur by a sequence of, first, production of matter from nothing, or origin of matter.

We are told that of all the radiometric dates that are measured, only a few percent are anomalous.
