What does absolute dating achieve in the context of fossils?

Absolute dating achieves specific age determination based on a chronology, allowing scientists to pinpoint a fossil's age within a specific timeframe. This method relies on techniques such as radiometric dating, which measures the decay of isotopes in minerals and organic materials. By determining the numerical age of fossils, researchers can place them accurately within the geological time scale, enabling a clearer understanding of the timeline of life on Earth and the evolution of species.

In contrast, comparative age analysis of different fossils, assessment of prehistoric environments, and identification of evolutionary relationships among species focus on relative dating, ecological contexts, or phylogenetic studies, rather than assigning a precise numerical age to a fossil. These methods are valuable but serve different purposes in the study of paleontology.
