Is dating fossils accurate
To present the fossil evidence as a relatively smooth transition leading to modern humans is akin to intellectual dishonesty. 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.
For example, it has been known since the s that the famous Cretaceous-Tertiary boundary, the line marking the end of the dinosaurs, was 65 million years old. Christians should not be afraid of radiometric dating methods. The first radiometric dates, generated about , showed that the Earth was hundreds of millions, or billions, of years old.
Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods. For many more examples of the consistancy of dating the same rocks with multiple methods, see Consistent Radiometric Dates by Joe Meert, a Geologist at the University of Florida. Phylogenetic trees are the family trees of particular groups of plants or animals, showing how all the species relate to each other.
It is impossible to give an evolutionary sequence to the human fossils because there is a coverage gap involving the dating methods which evolutionists believe are the most reliable—radiocarbon and potassium-argon K-Ar. Living penguins have been carbon dated and the results said that they had died 8, years ago! The average 14C estimated age for all the layers from these three time periods was approximately 50, years.
From the s onwards, geologists noted how fossils became more complex through time. They also give correlating dates of rocks when the proper methods of sampling are used. Mistakes are sometimes made but are usually caught by the various checks employed in the well-designed experiment.

Since such isotopes are thought The number of neutrons in the nucleus can vary in any given type of atom. Get the latest answers emailed to you or sign up for our free print newsletter. The objective was to gather data commonly ignored or censored by evolutionary standards of dating. Results from different techniques, often measured in rival labs, continually confirm each other.

Riddle, Does radiometric dating prove the earth is old? Living penguins have been carbon dated and the results said that they had died 8, years ago!

To do this, scientists use the main isotope of carbon, called carbon 12 C.
