Radiocarbon dating of rock
Age estimates can be cross-tested by using different isotope pairs.Results from different techniques, often measured in rival labs, continually confirm each other. It’s astonishing how much information exists about organizations dedicated to worthy causes. A Google search on charitable giving will produce countless websites.Today, innovative techniques provide further confirmation and understanding of the history of life.
Current understanding of the history of life is probably close to the truth because it is based on repeated and careful testing and consideration of data.Fossils can also show us how major crises, such as mass extinctions, happened, and how life recovered after them.If the fossils, or the dating of the fossils, could be shown to be inaccurate, all such information would have to be rejected as unsafe.Darwin and his contemporaries could never have imagined the improvements in resolution of stratigraphy that have come since 1859, nor guessed what fossils were to be found in the southern continents, nor predicted the huge increase in the number of amateur and professional paleontologists worldwide.
All these labors have not led to a single unexpected finding such as a human fossil from the time of the dinosaurs, or a Jurassic dinosaur in the same rocks as Silurian trilobites.The fossil record is fundamental to an understanding of evolution.
