Radiometric dating methods geology

New discoveries have filled in the gaps, and shown us in unimaginable detail the shape of the great ‘tree of life’.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.

Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods.

Some critics, particularly religious fundamentalists, argue that neither fossils nor dating can be trusted, and that their interpretations are better.

Other critics, perhaps more familiar with the data, question certain aspects of the quality of the fossil record and of its dating.

These skeptics do not provide scientific evidence for their views.

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.

The rejection of the validity of fossils and of dating by religious fundamentalists creates a problem for them: Fossil sequences were recognized and established in their broad outlines long before Charles Darwin had even thought of evolution.

Early geologists, in the 1700s and 1800s, noticed how fossils seemed to occur in sequences: certain assemblages of fossils were always found below other assemblages. Since 1859, paleontologists, or fossil experts, have searched the world for fossils.

In the past 150 years they have not found any fossils that Darwin would not have expected.

These demonstrate that, of course, we do not know everything (and clearly never will), but we know enough.

  1. Since 1984, Generation 1 Optimus Prime has received the largest number of toys for any single Transformers character, a testament to the character's enduring popularity and status as a hero to many fans.

  2. This is despite the reality that factors other than religious motivation likely played a major part in Mateen’s horrific act.
